我尝试过：

What I have tried:

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  
worksheet = workbook.Sheets["Sheet1"];
worksheet = workbook.ActiveSheet;
// changing the name of active sheet  
worksheet.Name = "Exported from gridview";
// storing header part in Excel  
for (int i = 1; i < dataGridView4.Columns.Count+1; i++)
{
	worksheet.Cells[1, i] = dataGridView4.Columns[i - 1].HeaderText;
}
// storing Each row and column value to excel sheet  
for (int i = 0; i < dataGridView4.Rows.Count - 1; i++)
{
	for (int j = 0; j < dataGridView4.Columns.Count; j++)
	{
		worksheet.Cells[i + 2, j + 1] = dataGridView4.Rows[i].Cells[j].Value.ToString();
	}
}
// save the application  
workbook.SaveAs("Desktop:\\output.xls", Type.Missing);

推荐答案

如果你想把它保存在其他地方，改变这一行。



之后，查询/询问有关用户输入或传递参数的问题。

Change this line, if you want to save it somewhere else.

After that, lookup / ask questions about "user input", or "passing parameters".

workbook.SaveAs("Desktop:\\output.xls", Type.Missing);
