问题描述

如何在窗口应用程序中从Gridview导出记录c＃
在Excel文件中记录不显示... 

 private void btn_Export_Click（object sender，EventArgs e）
 {
 
 Microsoft.Office.Interop.Excel ._Application excel = new Microsoft.Office.Interop.Excel.Application（）; 
 Microsoft.Office.Interop.Excel._Workbook workbook = excel.Workbooks.Add（Type.Missing）; 
 Microsoft.Office.Interop.Excel._Worksheet worksheet = null; 
 
尝试
 {
 
 worksheet = workbook.ActiveSheet; 
 
 worksheet.Name =ExportedFromDatGrid; 
 
 int cellRowIndex = 1; 
 int cellColumnIndex = 1; 
 
 //遍历每一行并从每列读取值。 
 for（int i = 0; i< dataGridView.Rows.Count  -  1; i ++）
 {
 for（int j = 0; j< dataGridView.Columns.Count; j ++ ）
 {
 // Excel索引从1,1开始。由于第一行将具有列标题，因此添加条件检查。 
 if（cellRowIndex == 1）
 {
 worksheet.Cells [cellRowIndex，cellColumnIndex] = dataGridView.Columns [j] .HeaderText; 
} 
 else 
 {
 worksheet.Cells [cellRowIndex，cellColumnIndex] = dataGridView.Rows [i] .Cells [j] .Value.ToString（）; 
} 
 cellColumnIndex ++; 
} 
 cellColumnIndex = 1; 
 cellRowIndex ++; 
} 
 
 //获取要从用户保存的Excel的位置和文件名。 
 SaveFileDialog saveDialog = new SaveFileDialog（）; 
 saveDialog.Filter =Excel文件（* .xlsx）| * .xlsx |所有文件（*。*）| *。*; 
 saveDialog.FilterIndex = 2; 
 
 if（saveDialog.ShowDialog（）== System.Windows.Forms.DialogResult.OK）
 {
 workbook.SaveAs（saveDialog.FileName）; 
 MessageBox.Show（导出成功）; 
} 
} 
 catch（System.Exception ex）
 {
 MessageBox.Show（ex.Message）; 
} 
最后
 {
 excel.Quit（）; 
 workbook = null; 
 excel = null; 
} 
 
 
}
