我正在尝试从页面导出网格视图的数据。但是当我将数据导出到excel文件时，它会导出整个页面。我只想导出网格视图的数据。我已经通过几个链接，但没有发现我自己满意。以下是我的导出代码。
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
using (StringWriter sw = new StringWriter())
{
HtmlTextWriter hw = new HtmlTextWriter(sw);
//To Export all pages
gvWorkOrder.AllowPaging = false;
this.LoadData();
gvWorkOrder.HeaderRow.BackColor = Color.White;
foreach (TableCell cell in gvWorkOrder.HeaderRow.Cells)
{
cell.BackColor = gvWorkOrder.HeaderStyle.BackColor;
}
foreach (GridViewRow row in gvWorkOrder.Rows)
{
row.BackColor = Color.White;
foreach (TableCell cell in row.Cells)
{
if (row.RowIndex % 2 == 0)
{
cell.BackColor = gvWorkOrder.AlternatingRowStyle.BackColor;
}
else
{
cell.BackColor = gvWorkOrder.RowStyle.BackColor;
}
cell.CssClass = "textmode";
}
}
gvWorkOrder.RenderControl(hw);
//style to format numbers to string
string style = @"<style> .textmode { } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
这是我的aspx页面。

安装软件包 ExcelLibrary.SpreadShee t 并创建如下方法。 您需要根据要导出到Excel工作表的记录创建数据表。
public string Export(DataTable dt)
{
Workbook workbook = new Workbook();
Worksheet sheet = new Worksheet(WorkSheetName);
workbook.Worksheets.Add(sheet);
// Adding Columns in Sheet
int c = 0, r = 0;
foreach (DataColumn column in dt.Columns)
{
sheet.Cells[r, c] = new Cell(column.ColumnName);
c++;
}
// Adding Records into sheet
r = 1;
for (int i = 0; i < dt.Rows.Count; i++)
{
for (c = 0; c < dt.Columns.Count; c++)
{
object o = dt.Rows[i][c];
int ii;
if (o == DBNull.Value)
sheet.Cells[r, c] = new Cell("");
else if (int.TryParse(o.ToString(), out ii))
sheet.Cells[r, c] = new Cell(ii);
else
sheet.Cells[r, c] = new Cell(o);
}
r++;
}
// Append Extra rows to comfort Open excel > 2003
if (dt.Rows.Count < MinRow)
{
r++;
for (int i = 0; i < MinRow; i++)
{
for (c = 0; c < 50; c++)
{
sheet.Cells[r, c] = new Cell("");
}
r++;
}
}
string fileName = Guid.NewGuid().ToString("N") + ".xls";
if (!Directory.Exists(DestinationRootFolder))
{
Directory.CreateDirectory(DestinationRootFolder);
}
workbook.Save(fileName);
return fileName;
}
此函数将返回创建的excel文件的路径。你可以用它来回复写下载开始。
HttpResponse httpResponse = Response;
httpResponse.Clear();
HttpContext.Current.Response.ContentType = "application/ms-excel";
httpResponse.AddHeader("content-disposition", "attachment;filename=" + tName);
using (MemoryStream memoryStream = new MemoryStream())
{
try
{
using (FileStream fileStream = new FileStream(fName, FileMode.Open))
{
fileStream.CopyTo(memoryStream);
}
memoryStream.WriteTo(httpResponse.OutputStream);
}
finally
{
memoryStream.Close();
File.Delete(fName);
}
}
httpResponse.End();
注意：您需要在目录中写入权限才能编写此excel文件。

我有一个将GridView数据导出（或转换）为Excel文件的示例。
我使用iTextSharp使它工作。这是我的代码：Exporting GridView to Excel。
