我有一个数据网格视图,我已导出到Excel工作表。代码运行良好,但当另存为对话框出现并保存文件时,我找不到文件,也没有出现错误。
private void button1_Click(object sender, EventArgs e)
{
try
{
using (new ExcelUILanguageHelper())
{
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "Execl files (*.xls)|*.xls";
saveFileDialog.FilterIndex = 0;
saveFileDialog.RestoreDirectory = true;
saveFileDialog.CreatePrompt = true;
saveFileDialog.Title = "Export Excel File To";
Excel.ApplicationClass ExcelApp = new Excel.ApplicationClass();
ExcelApp.Application.Workbooks.Add(Type.Missing);
ExcelApp.Columns.ColumnWidth = 30;
for (int i = 0; i < DGData.Rows.Count; i++)
{
DataGridViewRow row = DGData.Rows[i];
for (int j = 0; j < row.Cells.Count; j++)
{
ExcelApp.Cells[i + 1, j + 1] = row.Cells[j].ToString();
}
}
ExcelApp.ActiveWorkbook.SaveCopyAs(saveFileDialog.ShowDialog());
ExcelApp.ActiveWorkbook.Saved = true;
ExcelApp.Quit();
}
}
catch (Exception ex)
{
MessageBox.Show("Cancelled Operation");
this.Close();
}
}
答案 0 :(得分:5)
致电时
saveFileDialog.ShowDialog()
它返回一个DialogResult而不是所选的文件名。 SaveCopyAs方法需要一个文件名。
查看SaveFileDialog here的教程,了解如何获取所选文件名。它应该是这样的:
private void Form1_DoubleClick(object sender, System.EventArgs e)
{
if( this.saveFileDialog1.ShowDialog() == DialogResult.OK )
{
MessageBox.Show("The Save button was clicked or the Enter key was pressed" +
"\nThe file would have been saved as " +
this.saveFileDialog1.FileName);
}
else
MessageBox.Show("The Cancel button was clicked or Esc was pressed");
}
