这里我用gridview数据创建excel文件,代码如下

Response.ClearContent();
            Response.Buffer = true;
            Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "Customers.xls"));
            Response.ContentType = "application/ms-excel";
            StringWriter sw = new StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);
            GridView1.AllowPaging = false;           
            //Change the Header Row back to white color
            GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");
            //Applying stlye to gridview header cells
            for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
            {
                GridView1.HeaderRow.Cells[i].Style.Add("background-color", "#df5015");
            }
            GridView1.RenderControl(htw);
            Response.Write(sw.ToString());
            Response.End();

它运行正常,但是如果我将gridview属性设置为 AllowPaging =&#34; true&#34; ,excel文件只包含分页1数据,这里我如何导出从gridview到excel的所有数据。

在您的aspx页面中,设置网格的 AllowPaging =“true”

在您的代码隐藏文件中更改您的代码,

GridView1.AllowPaging = false;    
// BIND YOUR GRID HERE AGAIN

Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "Customers.xls"));
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);

//Change the Header Row back to white color
GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");
//Applying stlye to gridview header cells
for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
{
GridView1.HeaderRow.Cells[i].Style.Add("background-color", "#df5015");
}
GridView1.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();

我假设您使用存储在public string GetImagefromWord(string filePath) { Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application(); object miss = System.Reflection.Missing.Value; Microsoft.Office.Interop.Word.Document docs = word.Documents.Open(filePath, miss, miss, miss, miss); foreach (Microsoft.Office.Interop.Word.Row aRow in docs.Tables[0].Rows) { foreach (Microsoft.Office.Interop.Word.Cell aCell in aRow.Cells) { string xml = aCell.Range.XML; XmlDocument xdoc = new XmlDocument(); xdoc.LoadXml(xml); ****//xpictNode-Node of word XML having Image**** string imageType = xpictNode.Attributes["w:name"].Value.Substring(xpictNode.Attributes["w:name"].Value.LastIndexOf('.') + 1); string path = Path.GetDirectoryName(Application.ExecutablePath); byte[] byteBuffer = Convert.FromBase64String(xdoc.xpictNode.InnerText); MemoryStream memoryStream = new MemoryStream(byteBuffer); string img = "&nbsp;&nbsp;<img src= data:image/bmp;base64," + Convert.ToBase64String(File.ReadAllBytes(GetImageString(memoryStream, path, imageType))) + " />"; //Function GetImageString() is shown above } } } GridViewDataSet中的数据填充DataTable

如果是这样,只需获取该变量,并将其传递给我的“导出到Excel”C#库,它将为您创建一个真实的.xlsx文件,并可以将其直接传递到您的网页List<>

可以在此处找到“导出到Excel”类的完整源代码:

Export to Excel

您不希望这样做的唯一原因是,如果您特别希望自己的Excel包含class Employee; List<Employee> listOfEmployees = new List<Employee>(); ... GridView1.DataSource = listOfEmployees; ... // The following ASP.Net code gets run when I click on my "Export to Excel" button. protected void btnExportToExcel_Click(object sender, EventArgs e) { // It doesn't get much easier than this... CreateExcelFile.CreateExcelDocument(listOfEmployees, "Employees.xlsx", Response); } 中显示的值,而不是通过GridView修改它们功能

我的建议只会导出绑定到GridView的原始数据。
