我在将数据导出到 Excel 时遇到问题。以下似乎将 gridview 渲染到我的 View 中,而不是提示用户使用 Excel 打开,我已经安装在我的机器上。
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?
最佳答案
我试过你的代码,它工作得很好。
创建文件没有任何问题,这是我使用的代码(这是您的代码,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");
}
关于asp.net-mvc - 使用 ASP.NET MVC 4 C# 将数据导出到 Excel 文件正在呈现到 View 中,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/16346227/
