如何使用 IronXL 以 C# 建立 CSV 檔案

// Import the IronXL library
using IronXL;

class Program
{
    static void Main()
    {
        // Load an existing workbook
        WorkBook wb = WorkBook.Load("Normal_Excel_File.xlsx"); // You can import .xls, .csv, or .tsv files

        // Save the workbook to a CSV file. This will save the first worksheet as a CSV.
        wb.SaveAsCsv("SaveAsCSV.csv", ","); // This will output: SaveAsCSV.Sheet1.csv

        // Alternative: Save a specific worksheet as CSV
        WorkSheet sheet = wb.GetWorkSheet("Sheet1");
        sheet.SaveAsCsv("SpecificSheet.csv", ",");

        // You can also use different delimiters
        wb.SaveAsCsv("TabDelimited.csv", "\t"); // Tab-delimited
        wb.SaveAsCsv("PipeDelimited.csv", "|"); // Pipe-delimited
    }
}
