我在将所有数据导出到Excel文件时遇到问题。我只设法从gridview的第一页导出数据。我是否知道导出数据的正确方法,包括其他页面中的数据?非常感谢。
protected void bn_export_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition","attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
gv_getGameDetails.AllowPaging = false;
//Change the Header Row back to white color
gv_getGameDetails.HeaderRow.Style.Add("background-color", "#FFFFFF");
gv_getGameDetails.HeaderRow.Cells[0].Style.Add("background-color", " #262626");
gv_getGameDetails.HeaderRow.Cells[1].Style.Add("background-color", " #262626");
gv_getGameDetails.HeaderRow.Cells[2].Style.Add("background-color", " #262626");
gv_getGameDetails.HeaderRow.Cells[3].Style.Add("background-color", " #262626");
this.RemoveControls(gv_getGameDetails);
gv_getGameDetails.RenderControl(hw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();

这可能会有所帮助。它重复所有列和行并导出到Excel工作表。您需要添加Microsoft.Office.Interop.Excel
private void button2_Click(object sender, EventArgs e)
{
// creating Excel Application
Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
// creating new WorkBook within Excel application
Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);
// creating new Excelsheet in workbook
Microsoft.Office.Interop.Excel._Worksheet worksheet = null;
// see the excel sheet behind the program
app.Visible = true;
// get the reference of first sheet. By default its name is Sheet1.
// store its reference to worksheet
try
{
//Fixed:(Microsoft.Office.Interop.Excel.Worksheet)
worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets["Sheet1"];
worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.ActiveSheet;
// changing the name of active sheet
worksheet.Name = "YourChosenSheetName";
// storing header part in Excel
for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
{
worksheet.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;
}
// storing Each row and column value to excel sheet
for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
{
for (int j = 0; j < dataGridView1.Columns.Count; j++)
{
worksheet.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
}
}
// save the application
string fileName = String.Empty;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "Excel files |*.xls|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
fileName = saveFileDialog1.FileName;
//Fixed-old code :11 para->add 1:Type.Missing
workbook.SaveAs(fileName, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
}
else
return;
// Exit from the application
//app.Quit();
}
catch (System.Exception ex)
{
}
finally
{
app.Quit();
workbook = null;
app = null;
}
}
