Question

我有一个网格视图。我试图在excel中导出。代码如下：

public override void VerifyRenderingInServerForm(Control gvReport1)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        string attachment = "attachment; filename=Report.xls";
        Response.ClearContent();
        Response.AddHeader("content-disposition", attachment);
        Response.ContentType = "application/vnd.ms-excel";
        Response.Charset = "";
        this.EnableViewState = false;
        StringWriter stw = new StringWriter();
        HtmlTextWriter htextw = new HtmlTextWriter(stw);
        gvReport1.RenderControl(htextw);
        Response.Write(stw.ToString());
        Response.End();
    }

现在的问题是excel文件正在打开，但数据没有显示出来。我猜数据没有被读取，更奇怪的是我有两个网页。在第一个网页中，导出到Excel的工作正常，但在第二个页面上它不起作用。

可能有一种更优雅的方式......

有。

看看这个： Export to Excel library

这是一个完全免费的库，它使用Microsoft的Open XML库来创建真正的Excel 2007 .xlsx文件。

您所有所要做的就是调用一个“ CreateExcelDocument ”函数，然后传入DataTable，DataSet或List＆lt;＆gt;其中包含用于填充GridView的数据。

// Step 1: Create a DataSet, and put some sample data in it DataSet ds = CreateSampleData(); // Step 2: Create the Excel .xlsx file try { string excelFilename = "C:\\Sample.xlsx"; CreateExcelFile.CreateExcelDocument(ds, excelFilename); } catch (Exception ex) { MessageBox.Show("Couldn't create Excel file.\r\nException: " + ex.Message); return; }

享受，祝你好运！

Answer 2

Response.Write(stw.ToString());

不正确，这只会返回类型名称，您需要先将RenderControl的输出写入字符串，然后使用Response.Write（）写入字符串内容。

编辑：以下是如何获取渲染控件内容的示例：

     // Obtain the content about to be rendered.
     var ms = new MemoryStream();
     var w = new StreamWriter(ms);
     var r = new StreamReader(ms);
     using (var htmlw = new HtmlTextWriter(w))
     {
        gvReport1.RenderControl(htmlw);
        htmlw.Flush();
     }

     ms.Position = 0;
     var content = r.ReadToEnd();
     r.Close();

可能有一种更优雅的方式......
