DefaultWorkSheet：處理單張工作表檔案時的快速存取
First() 或 FirstOrDefault()，適用於工作表名稱可能改變情況的安全選項

獲得 ExcelSheet workSheet 後，您可以從中獲取任何型別的資料並在其上執行所有的 Excel 函式。如需更複雜的工作表操作，請參閱在 C# 中打開 Excel 工作表的指南。

如何存取 WorkSheet 的資料？

資料可以通過此過程從 ExcelSheet workSheet 中存取：

我可以從儲存格中讀取哪些資料型別？

using IronXL;

// Accessing data as a string
string dataString = workSheet["A1"].ToString();

// Accessing data as an integer
int dataInt = workSheet["B1"].Int32Value;

using IronXL;

// Accessing data as a string
string dataString = workSheet["A1"].ToString();

// Accessing data as an integer
int dataInt = workSheet["B1"].Int32Value;

Imports IronXL

' Accessing data as a string
Dim dataString As String = workSheet("A1").ToString()

' Accessing data as an integer
Dim dataInt As Integer = workSheet("B1").Int32Value

Imports IronXL

' Accessing data as a string
Dim dataString As String = workSheet("A1").ToString()

' Accessing data as an integer
Dim dataInt As Integer = workSheet("B1").Int32Value

IronXL 為不同的資料型別提供多種值存取器：

StringValue：讀取文字資料
Int32Value：讀取整數
DoubleValue：讀取小數
DateTimeValue：讀取日期
BoolValue：讀取真/假值

如何一次讀取多個儲存格？

您還可以從特定欄位的多個儲存格中獲取資料：

foreach (var cell in workSheet["A2:A10"])
{
    Console.WriteLine("Value is: {0}", cell.Text);
}

foreach (var cell in workSheet["A2:A10"])
{
    Console.WriteLine("Value is: {0}", cell.Text);
}

For Each cell In workSheet("A2:A10")
	Console.WriteLine("Value is: {0}", cell.Text)
Next cell

For Each cell In workSheet("A2:A10")
	Console.WriteLine("Value is: {0}", cell.Text)
Next cell

這將顯示從 A2 儲存格到 A10 儲存格的值。要了解更高級的範圍選擇技巧，請參閱選擇範圍教程。

完整的實現看起來如何？

這裡提供了上述細節的完整程式碼範例：

using IronXL;
using System;

// Load an Excel file
WorkBook workBook = WorkBook.Load("sample.xlsx");
WorkSheet workSheet = workBook.GetWorkSheet("Sheet1");

如何將 Excel WorkSheet 讀取為 DataTable？

using IronXL，可以輕鬆地將 Excel WorkSheet 作為 DataTable 來處理。當您需要將 Excel 資料整合進現有資料處理流水線或將資料綁定到 UI 控件時，此功能特別有用。

基本轉換方法是什麼？

using IronXL;
using System.Data;

// Convert worksheet to DataTable
DataTable dt = workSheet.ToDataTable();

using IronXL;
using System.Data;

// Convert worksheet to DataTable
DataTable dt = workSheet.ToDataTable();

Imports IronXL
Imports System.Data

' Convert worksheet to DataTable
Dim dt As DataTable = workSheet.ToDataTable()

Imports IronXL
Imports System.Data

' Convert worksheet to DataTable
Dim dt As DataTable = workSheet.ToDataTable()

如何使用第一行作為欄名？

要將 ExcelSheet 的第一行用作 DataTable ColumnName：

using IronXL;
using System.Data;

// Convert worksheet to DataTable with the first row as column names
DataTable dt = workSheet.ToDataTable(true);

using IronXL;
using System.Data;

// Convert worksheet to DataTable with the first row as column names
DataTable dt = workSheet.ToDataTable(true);

Imports IronXL
Imports System.Data

' Convert worksheet to DataTable with the first row as column names
Dim dt As DataTable = workSheet.ToDataTable(True)

Imports IronXL
Imports System.Data

' Convert worksheet to DataTable with the first row as column names
Dim dt As DataTable = workSheet.ToDataTable(True)

ToDataTable() 的布林參數將第一行設定為 DataTable 的欄名。預設情況下，其值為 False。這在處理包含標頭的結構化資料時特別有用。

如何遍歷 DataTable？

using IronXL;
using System;
using System.Data;

// Load the Excel workbook
WorkBook workBook = WorkBook.Load("sample.xlsx");

// Get the specified WorkSheet
WorkSheet workSheet = workBook.GetWorkSheet("Sheet1");

// Convert WorkSheet to DataTable
DataTable dt = workSheet.ToDataTable(true); // Use first row as column names

// Iterate through rows and columns and display data
foreach (DataRow row in dt.Rows) // Access rows
{
    for (int i = 0; i < dt.Columns.Count; i++) // Access columns of corresponding row
    {
        Console.Write(row[i] + " ");
    }
    Console.WriteLine();
}

using IronXL;
using System;
using System.Data;

// Load the Excel workbook
WorkBook workBook = WorkBook.Load("sample.xlsx");

// Get the specified WorkSheet
WorkSheet workSheet = workBook.GetWorkSheet("Sheet1");

// Convert WorkSheet to DataTable
DataTable dt = workSheet.ToDataTable(true); // Use first row as column names

// Iterate through rows and columns and display data
foreach (DataRow row in dt.Rows) // Access rows
{
    for (int i = 0; i < dt.Columns.Count; i++) // Access columns of corresponding row
    {
        Console.Write(row[i] + " ");
    }
    Console.WriteLine();
}

Imports IronXL
Imports System
Imports System.Data

' Load the Excel workbook
Dim workBook As WorkBook = WorkBook.Load("sample.xlsx")

' Get the specified WorkSheet
Dim workSheet As WorkSheet = workBook.GetWorkSheet("Sheet1")

' Convert WorkSheet to DataTable
Dim dt As DataTable = workSheet.ToDataTable(True) ' Use first row as column names

' Iterate through rows and columns and display data
For Each row As DataRow In dt.Rows ' Access rows
    For i As Integer = 0 To dt.Columns.Count - 1 ' Access columns of corresponding row
        Console.Write(row(i) & " ")
    Next
    Console.WriteLine()
Next

Imports IronXL
Imports System
Imports System.Data

' Load the Excel workbook
Dim workBook As WorkBook = WorkBook.Load("sample.xlsx")

' Get the specified WorkSheet
Dim workSheet As WorkSheet = workBook.GetWorkSheet("Sheet1")

' Convert WorkSheet to DataTable
Dim dt As DataTable = workSheet.ToDataTable(True) ' Use first row as column names

' Iterate through rows and columns and display data
For Each row As DataRow In dt.Rows ' Access rows
    For i As Integer = 0 To dt.Columns.Count - 1 ' Access columns of corresponding row
        Console.Write(row(i) & " ")
    Next
    Console.WriteLine()
Next

使用上述程式碼可以存取 WorkSheet 的每個儲存格值並按需要使用。如需了解更高階的 DataTable 操作，請參考導入和匯出為 DataSet 的指南。

如何將 Excel 檔案讀取為 DataSet？

IronXL 提供了一個簡單的函式來將整個 Excel 檔案（WorkBook）作為 DataSet 使用。使用 ToDataSet 方法將整個工作簿轉換為 DataSet。
在此範例中，我們將看到如何將 Excel 檔案用作 DataSet。

如何將工作簿轉換為 DataSet？

using IronXL;
using System;
using System.Data;

// Load the Excel workbook
WorkBook workBook = WorkBook.Load("sample.xlsx");

// Convert the WorkBook to a DataSet
DataSet ds = workBook.ToDataSet();

// Iterate through tables in the DataSet and display table names
foreach (DataTable dt in ds.Tables)
{
    Console.WriteLine(dt.TableName);
}

using IronXL;
using System;
using System.Data;

// Load the Excel workbook
WorkBook workBook = WorkBook.Load("sample.xlsx");

// Convert the WorkBook to a DataSet
DataSet ds = workBook.ToDataSet();

// Iterate through tables in the DataSet and display table names
foreach (DataTable dt in ds.Tables)
{
    Console.WriteLine(dt.TableName);
}

Imports IronXL
Imports System
Imports System.Data

' Load the Excel workbook
Dim workBook As WorkBook = WorkBook.Load("sample.xlsx")

' Convert the WorkBook to a DataSet
Dim ds As DataSet = workBook.ToDataSet()

' Iterate through tables in the DataSet and display table names
For Each dt As DataTable In ds.Tables
    Console.WriteLine(dt.TableName)
Next

Imports IronXL
Imports System
Imports System.Data

' Load the Excel workbook
Dim workBook As WorkBook = WorkBook.Load("sample.xlsx")

' Convert the WorkBook to a DataSet
Dim ds As DataSet = workBook.ToDataSet()

' Iterate through tables in the DataSet and display table names
For Each dt As DataTable In ds.Tables
    Console.WriteLine(dt.TableName)
Next

上述程式碼的輸出如下所示：

如何跨所有工作表存取每個儲存格值？

在上述範例中，我們可以輕鬆地將 Excel 檔案解析為 DataSet，並將 Excel 檔案的每個 DataTable 作為 DataTable 使用。深入了解如何在此處解析 Excel 為 DataSet，其中有程式碼範例。

讓我們再看一個如何存取所有 ExcelSheets 的每個儲存格值的範例。在這裡，我們可以存取 Excel 檔案每個 ExcelSheet 的每個儲存格值。

using IronXL;
using System;

// Load the Excel workbook
WorkBook workBook = WorkBook.Load("sample.xlsx");

// Iterate through every WorkSheet in the WorkBook
foreach (WorkSheet workSheet in workBook.WorkSheets)
{
    Console.WriteLine($"Worksheet: {workSheet.Name}");

    // Access each filled cell value on the current WorkSheet
    foreach (var cell in workSheet.FilledCells)
    {
        Console.WriteLine($"{cell.Address}: {cell.Text}");
    }
}

using IronXL;
using System;

// Load the Excel workbook
WorkBook workBook = WorkBook.Load("sample.xlsx");

// Iterate through every WorkSheet in the WorkBook
foreach (WorkSheet workSheet in workBook.WorkSheets)
{
    Console.WriteLine($"Worksheet: {workSheet.Name}");

    // Access each filled cell value on the current WorkSheet
    foreach (var cell in workSheet.FilledCells)
    {
        Console.WriteLine($"{cell.Address}: {cell.Text}");
    }
}

使用上述範例，方便地存取 Excel 檔案每個 ExcelSheet 的每個儲存格值。這種方法特別適合處理帶有多張工作表的工作簿，其中資料分佈在不同的標籤中。
