Steps to Read Excel Files using IronXL
Now, let's go through the steps to read an Excel file using IronXL in our C# Console Application. The following code snippet allows you to read Excel files in the C# console application:
using IronXL;
class Program
{
public static void Main()
{
// Specify the path to the Excel file
string excelFilePath = "path/to/your/excel/file.xlsx";
// Create a WorkBook object by loading an existing Excel file
WorkBook workBook = WorkBook.Load(excelFilePath);
// Access the first worksheet in the workbook
WorkSheet workSheet = workBook.WorkSheets[0];
// Iterate through each row in the worksheet
foreach (var row in workSheet.Rows)
{
// Iterate through each cell in the row
foreach (var cell in row)
{
// Print the text of the cell followed by a tab
Console.Write(cell.Text + "\t");
}
// Move to the next line after each row
Console.WriteLine();
}
// Close the workbook to free resources
workBook.Close();
}
}
using IronXL;
class Program
{
public static void Main()
{
// Specify the path to the Excel file
string excelFilePath = "path/to/your/excel/file.xlsx";
// Create a WorkBook object by loading an existing Excel file
WorkBook workBook = WorkBook.Load(excelFilePath);
// Access the first worksheet in the workbook
WorkSheet workSheet = workBook.WorkSheets[0];
// Iterate through each row in the worksheet
foreach (var row in workSheet.Rows)
{
// Iterate through each cell in the row
foreach (var cell in row)
{
// Print the text of the cell followed by a tab
Console.Write(cell.Text + "\t");
}
// Move to the next line after each row
Console.WriteLine();
}
// Close the workbook to free resources
workBook.Close();
}
}
Imports Microsoft.VisualBasic
Imports IronXL
Friend Class Program
Public Shared Sub Main()
' Specify the path to the Excel file
Dim excelFilePath As String = "path/to/your/excel/file.xlsx"
' Create a WorkBook object by loading an existing Excel file
Dim workBook As WorkBook = WorkBook.Load(excelFilePath)
' Access the first worksheet in the workbook
Dim workSheet As WorkSheet = workBook.WorkSheets(0)
' Iterate through each row in the worksheet
For Each row In workSheet.Rows
' Iterate through each cell in the row
For Each cell In row
' Print the text of the cell followed by a tab
Console.Write(cell.Text & vbTab)
Next cell
' Move to the next line after each row
Console.WriteLine()
Next row
' Close the workbook to free resources
workBook.Close()
End Sub
End Class
This C# code snippet demonstrates how to use the IronXL library to read data from an Excel file and display it in a console application. The following Excel file will be read and displayed on the console window:
Now, let's break down the code step by step:
Importing the IronXL Namespace
using IronXL;
using IronXL;
Imports IronXL
This line imports the IronXL namespace, which contains classes and methods for working with any Excel document.
Main Method
public static void Main() {
// Main method where the program execution begins
}
public static void Main() {
// Main method where the program execution begins
}
Public Shared Sub Main()
' Main method where the program execution begins
End Sub
The Main method is the entry point of the application. We will write the above code snippet in this main method.
Excel File Path
string excelFilePath = "path/to/your/excel/file.xlsx";
string excelFilePath = "path/to/your/excel/file.xlsx";
Dim excelFilePath As String = "path/to/your/excel/file.xlsx"
This line specifies the path to the Excel file that you want to read. Replace "path/to/your/excel/file.xlsx" with the actual path to your Excel file.
Load Excel File
WorkBook workBook = WorkBook.Load(excelFilePath);
WorkBook workBook = WorkBook.Load(excelFilePath);
Dim workBook As WorkBook = WorkBook.Load(excelFilePath)
The WorkBook.Load() method is used to load the Excel file specified by excelFilePath into a WorkBook (Excel) object named workBook.
Accessing Worksheet
WorkSheet workSheet = workBook.WorkSheets[0];
WorkSheet workSheet = workBook.WorkSheets[0];
Dim workSheet As WorkSheet = workBook.WorkSheets(0)
This line accesses the first Excel sheet in the workbook (workBook.WorkSheets [0]) and assigns it to an Excel WorkSheet object named workSheet.
Iterating Through Rows and Columns
foreach (var row in workSheet.Rows)
{
foreach (var cell in row)
{
Console.Write(cell.Text + "\t");
}
Console.WriteLine();
}
foreach (var row in workSheet.Rows)
{
foreach (var cell in row)
{
Console.Write(cell.Text + "\t");
}
Console.WriteLine();
}
Imports Microsoft.VisualBasic
For Each row In workSheet.Rows
For Each cell In row
Console.Write(cell.Text & vbTab)
Next cell
Console.WriteLine()
Next row
These nested foreach loops iterate through each row and column in the worksheet. For each cell, the cell's text value (cell.Text) is printed to the console, followed by a tab character ("\t"). After printing all cells in a row, a newline character is printed to move to the next row.
Closing the Workbook
workBook.Close();
workBook.Close();
workBook.Close()
Finally, the workBook.Close() method is called to close the workbook and release any resources associated with it.

Output
Upon running the application, the data from Excel file will be printed on the console window:
