源代碼：
private void ExportExcel(string fileName, DevExpress.XtraGrid.Views.Grid.GridView myDGV)
{
string saveFileName = "";
SaveFileDialog saveDialog = new SaveFileDialog();
saveDialog.DefaultExt = "xlsx";
saveDialog.Filter = "Excel文件|*.xlsx";
saveDialog.FileName = fileName;
saveDialog.ShowDialog();
saveFileName = saveDialog.FileName;
if (saveFileName.IndexOf(":") < 0) return; //被點了取消
Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
if (xlApp == null)
{
MessageBox.Show("無法創建Excel對象，可能您的機子未安裝Excel");
return;
}
Microsoft.Office.Interop.Excel.Workbooks workbooks = xlApp.Workbooks;
Microsoft.Office.Interop.Excel.Workbook workbook = workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet);
Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];//取得sheet1
int j = 0;//篩選掉隱藏的列
//寫入標題
for (int i = 0; i < myDGV.Columns.Count; i++)
{
//myDGV.Columns[i].HeaderText;
if (myDGV.Columns[i].Visible == true)
{
worksheet.Cells[1, j + 1] = myDGV.Columns[i].Caption;
j++;
}
}
//寫入數值
for (int r = 0; r < myDGV.RowCount; r++)
{
int k = 0;//篩選掉隱藏的列
for (int i = 0; i < myDGV.Columns.Count; i++)
{
if (myDGV.Columns[i].Visible == true)
{
worksheet.Cells[r + 2, k + 1] = myDGV.GetRowCellValue(r, myDGV.Columns[i]);
k++;
}
}
System.Windows.Forms.Application.DoEvents();
}
worksheet.Columns.EntireColumn.AutoFit();//列寬自適應
if (saveFileName != "")
{
try
{
workbook.Saved = true;
workbook.SaveCopyAs(saveFileName);
}
catch (Exception ex)
{
MessageBox.Show("導出文件時出錯,文件可能正被打開！\n" + ex.Message);
}
}
xlApp.Quit();
GC.Collect();//強行銷毀
MyCommon.ShowMessageBox(this, fileName + ".xlsx 導出成功", "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
//導出按鈕事件
private void button3_Click(object sender, EventArgs e)
{
//第一個是名稱，第二個是gridview
ExportExcel("測試", gridView1);
}
需要注意的是：在導出中gridview中的列要按順序排列出來，要和前台顯示保持一致，這里增加了隱藏列的方法，可以將隱藏的列篩選出來，office中2010以下的版本需要修改
saveDialog.DefaultExt = "xls";
saveDialog.Filter = "Excel文件|*.xls";
以上的版本就不用修改了，動態創建出來了；
