我正在尝试使用DisplayName属性来修改导出到Excel文件的数据中的列标题。我想要＆＃34;我的名字＆＃34;但得到＆＃34; MyName＆＃34;。数据是从查询返回的数据，转换为List，然后转换为DataTable，然后导出到Excel。
我还能尝试什么？
有some discussion here表示正在添加此功能。
使用.NET Framework 4
public class MyExcelViewModel
{
private string myName;
//[System.ComponentModel.DisplayName("Mine Name")] // no effect
//[System.ComponentModel.DataAnnotations("My Name")] // doesn't compile
//[System.ComponentModel.DisplayNameAttribute("My Name")] // no effect
[Display(Name = "My Name")] // no effect
public string MyName { get; set; }
}
public class MyController : Controller
// initialize exportList
IList<MyExcelViewModel> exportList = new List<MyExcelViewModel>(fromQueryList.Count);
foreach (var value in fromQueryList)
{
exportList.Add(new MyExcelViewModel());
}
DataTable dataTable = ConvertListToDataTable(exportList); // convert to DataTable
Export_EPPlus(dataTable); // export
private void Export_EPPlus(DataTable dataTable)
{
using (ExcelPackage package = new ExcelPackage())
{
ExcelWorksheet worksheet = package.Workbook.Worksheets.Add(" Results");
// Load the datatable into the sheet, starting from cell A1.
worksheet.Cells["A1"].LoadFromDataTable(dataTable, true);
worksheet.View.FreezePanes(2, 1); // freeze first row & column
worksheet.Row(1).Style.Font.Bold = true;
worksheet.Cells[worksheet.Dimension.Address].AutoFitColumns(); // autofit column width
for (int rowNumber = worksheet.Dimension.Start.Row; rowNumber <= worksheet.Dimension.End.Row; rowNumber++)
{
int rowIndex = rowNumber % 2; // even => 0, odd => 1
ExcelRow excelRow = worksheet.Row(rowNumber);
ExcelFill excelFillRow = excelRow.Style.Fill;
excelFillRow.PatternType = ExcelFillStyle.Solid;
switch (rowIndex)
{
case 0:
excelFillRow.BackgroundColor.SetColor(System.Drawing.Color.White);
break;
case 1:
excelFillRow.BackgroundColor.SetColor(System.Drawing.Color.LightGray);
break;
}
}
try
{
// Write to client
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment; filename="Results-EPPlus.xlsx");
Response.BinaryWrite(package.GetAsByteArray());
}
catch (Exception ex)
{
System.Diagnostics.Trace.WriteLine("MyController.Export_EPPlus(): exception: " + ex);
}
}
}
public static DataTable ConvertListToDataTable<T>(this IList<T> data)
