DataGridView 导出到Excel代码
方法一（推荐使用这个方法，因为他可以另存为，哪个更快就要使用者测试了，这里只提供方法）：
/// <summary>
/// 收费项目---Excel
/// </summary>
private void BtnExcel_Click(object sender, EventArgs e)
{
if (DgvFeeInspection.Rows.Count == 0)
{
CountdownMsgFrm.ShowMsg("无法进行导出，请确定您已经查询出数据！");
return;
}
FunFee.ExportExcel("收费项目" + DateTime.Now.ToString("yyyy-MM-dd") + "", DgvFeeInspection);
}
/// <summary>
/// 导出到Excel方法
/// </summary>
/// <param name="fileName"></param>
/// <param name="myDGV"></param>
public void ExportExcel(string fileName, DataGridView myDGV)
{
string saveFileName = "";
SaveFileDialog saveDialog = new SaveFileDialog();
saveDialog.DefaultExt = "xls";
saveDialog.Filter = "Excel文件|*.xls";
saveDialog.FileName = fileName;
saveDialog.ShowDialog();
saveFileName = saveDialog.FileName;
if (saveFileName.IndexOf(":") < 0) return; //被点了取消
Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
if (xlApp == null)
{
MessageBox.Show("无法创建Excel对象，可能您的机子未安装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
//写入标题
for (int i = 0; i < myDGV.ColumnCount; i++)
{
worksheet.Cells[1, i + 1] = myDGV.Columns[i].HeaderText;
}
//写入数值
for (int r = 0; r < myDGV.Rows.Count; r++)
{
for (int i = 0; i < myDGV.ColumnCount; i++)
{
worksheet.Cells[r + 2, i + 1] = myDGV.Rows[r].Cells[i].Value;
}
System.Windows.Forms.Application.DoEvents();
}
worksheet.Columns.EntireColumn.AutoFit();//列宽自适应
//if (Microsoft.Office.Interop.cmbxType.Text != "Notification")
//{
// Excel.Range rg = worksheet.get_Range(worksheet.Cells[2, 2], worksheet.Cells[ds.Tables[0].Rows.Count + 1, 2]);
// rg.NumberFormat = "00000000";
//}
if (saveFileName != "")
{
try
{
workbook.Saved = true;
workbook.SaveCopyAs(saveFileName);
//fileSaved = true;
}
catch (Exception ex)
{
//fileSaved = false;
MessageBox.Show("导出文件时出错,文件可能正被打开！\n" + ex.Message);
}
}
xlApp.Quit();
GC.Collect();//强行销毁
//if (fileSaved && System.IO.File.Exists(saveFileName)) System.Diagnostics.Process.Start(saveFileName); //打开EXCEL
CountdownMsgFrm.ShowMsg(fileName + "生成成功!");
}
方法二：
DataGridView控件的数据导出到Excel代码,
/// <summary>
/// 将DataGridView控件中数据导出到Excel
/// </summary>
/// <param name="gridView">DataGridView对象</param>
/// <param name="isShowExcle">是否显示Excel界面</param>
/// <returns></returns>
public bool ExportDataGridview(DataGridView gridView, bool isShowExcle)
{
if (gridView.Rows.Count == 0)
return false;
//建立Excel对象
Excel.Application excel = new Excel.Application();
excel.Application.Workbooks.Add(true);
excel.Visible = isShowExcle;
//生成字段名称
for (int i = 0; i < gridView.ColumnCount; i++)
{
excel.Cells[1, i + 1] = gridView.Columns[i].HeaderText;
}
//填充数据
for (int i = 0; i < gridView.RowCount - 1; i++) //循环行
{
for (int j = 0; j < gridView.ColumnCount; j++) //循环列
{
if (gridView[j, i].ValueType == typeof(string)) //判断DataGirdView中数据的类型
{
excel.Cells[i + 2, j + 1] = "'" + gridView[j, i].Value.ToString();
}
else
{
excel.Cells[i + 2, j + 1] = gridView[j, i].Value.ToString();
}
}
}
return true;
}
private void button1_Click(object sender, EventArgs e)
{
this.ExportDataGridview(dataGridView1, true);
}
