我正在使用以下函数导出 Excel 文件。它工作正常。我将 SQL 数据库中的记录检索到数据表并导出 Excel 表。
public ActionResult ExporttoExcel()
{
DataTable dt = new DataTable();
SqlConnection con = new SqlConnection("Connection string here");
con.Open();
SqlCommand cmd = new SqlCommand("select * from Exportxcel", con);
dt.Load(cmd.ExecuteReader());
int total = 0;
foreach (DataRow row in dt.Rows)
{
int salaryvalue = Convert.ToInt32(row["Salary"]);
total = salaryvalue + total;
}
dt.Rows.Add(new object[] { "", "Total", total });
if (dt.Rows.Count > 0)
{
string filename = "ExcelExport.xls";
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
DataGrid dgGrid = new DataGrid();
dgGrid.DataSource = dt;
dgGrid.DataBind();
dgGrid.RenderControl(hw);
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
Response.Write(tw.ToString());
Response.End();
}
return View(dt);
}
我的问题是我需要在值绑定之前添加两个标题？如何做到这一点？我需要添加标题，作者如下屏幕截图。如何做到这一点？
