wpf文本框数据导出excel

以下是将 WPF 文本框中的数据导出到 Excel 的示例代码：

private void ExportToExcel_Click(object sender, RoutedEventArgs e)
{
    Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
    excel.Visible = true;
    Microsoft.Office.Interop.Excel.Workbook workbook = excel.Workbooks.Add(System.Reflection.Missing.Value);
    Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.ActiveSheet;

    worksheet.Cells[1, 1] = "Column 1 Header";
    worksheet.Cells[1, 2] = "Column 2 Header";
    worksheet.Cells[1, 3] = "Column 3 Header";

    int rowIndex = 2;
    foreach (object item in ListBox1.Items)
    {
        if (item is MyDataClass)
        {
            MyDataClass data = item as MyDataClass;
            worksheet.Cells[rowIndex, 1] = data.Column1;
            worksheet.Cells[rowIndex, 2] = data.Column2;
            worksheet.Cells[rowIndex, 3] = data.Column3;
            rowIndex++;
        }
    }

    workbook.SaveAs("ExportedData.xlsx", Microsoft.Office.Interop.Excel.XlFileFormat.xlOpenXMLWorkbook, System.Reflection.Missing.Value,
        System.Reflection.Missing.Value, false, false, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
        Microsoft.Office.Interop.Excel.XlSaveConflictResolution.xlUserResolution, true, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value);
}

在这里，我们使用 Microsoft.Office.Interop.Excel 库来创建一个新的 Excel 文件，并将 WPF ListBox 中的数据导出到该文件中。请注意，这只是一个示例，你需要根据你自己的需求进行修改。
