怎么将DataTable的数据导出到Excel中

Answer 1

下面的函数作用，将DataTable导出到EXCEL文件：
private void DataTabletoExcel(System.Data.DataTable tmpDataTable,string strFileName)
{
if (tmpDataTable == null)
{
return;
}
int rowNum = tmpDataTable.Rows.Count;
int columnNum = tmpDataTable.Columns.Count;
int rowIndex = 1;
int columnIndex = 0;

Excel.Application xlApp = new Excel.ApplicationClass();

xlApp.DefaultFilePath = "";
xlApp.DisplayAlerts = true;
xlApp.SheetsInNewWorkbook = 1;

Excel.Workbook xlBook = xlApp.Workbooks.
