使用如下代码，可将Datagridview的内容存入Excel表中：

using Microsoft.Office.Core;
                                using Excel= Microsoft.Office.Interop.Excel;

Excel.Application excelApp = new Excel.Application();

excelApp.Application.Workbooks.Add(true);

object misValue = System.Reflection.Missing.Value;

if(File.Exists("D:\\List.xls"))

{

File.Delete("D:\\List.xls");

excelApp.ActiveWorkbook.SaveAs(@"D:\List.xls", misValue, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);

}

else

{

excelApp.ActiveWorkbook.SaveAs(@"D:\List.xls", misValue, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);

}

string myPath = "D:\\List.xls";

excelApp.Workbooks.Open(myPath);

for (int i = 0; i < dataGridView1.ColumnCount; i++)

{

for (int j = 0; j < dataGridView1.RowCount - 1; j++)

{

excelApp.Cells[j + 2, i + 1] = dataGridView1[i, j].Value.ToString();

}

excelApp.Cells[1, i + 1] = dataGridView1.Columns[i].HeaderText;

}

excelApp.Visible = true;
