我无法将数据导出到Excel。以下似乎将gridview渲染到我的View中，而不是提示用户使用我在我的机器上安装的Excel进行打开。
Public ActionResult ExportToExcel()
{
var products = this.Repository.Products.ToList();
var grid = new GridView();
grid.DataSource = from p in products
select new
{
Id = p.Id,Name = p.Name
};
grid.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition","attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return View("MyView");
}
我究竟做错了什么？
解决方法
我已经尝试了你的代码，它的工作正常。
该文件正在创建没有任何问题，这是我使用的代码(这是你的代码，我只是更改了数据源进行测试)：

public ActionResult ExportToExcel()
{
var products = new System.Data.DataTable("teste");
products.Columns.Add("col1",typeof(int));
products.Columns.Add("col2",typeof(string));
products.Rows.Add(1,"product 1");
products.Rows.Add(2,"product 2");
products.Rows.Add(3,"product 3");
products.Rows.Add(4,"product 4");
products.Rows.Add(5,"product 5");
products.Rows.Add(6,"product 6");
products.Rows.Add(7,"product 7");
var grid = new GridView();
grid.DataSource = products;
grid.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition","attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return View("MyView");
}
