问题描述
我无法将数据导出到Excel中。下面似乎呈现GridView的到我的视图,而不是提示用户使用Excel,而我已经安装在我的机器上打开。
I am having trouble exporting data to Excel. The following seems to render the gridview into my View, instead of prompting the user to open with Excel, which I have installed on my machine.
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");
}
我在做什么错了?
What am I doing wrong?
推荐答案
我想你的code和它工作得很好。
正在没有任何问题,创建的文件,这是code我用(这是你的code,我只是改变了数据源进行测试):
I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):
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");
}
