Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application(); 
            // creating Excel Application
            Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);

            //Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();


            Microsoft.Office.Interop.Excel.Worksheet objSheet = new Microsoft.Office.Interop.Excel.Worksheet();
            Microsoft.Office.Interop.Excel.Workbook objWorkBook = null;


            //// creating new WorkBook within Excel application

            //Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);

 // 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

            objSheet = objWorkBook.Sheets["Sheet1"] as Microsoft.Office.Interop.Excel.Worksheet;

            objSheet = objWorkBook.ActiveSheet as Microsoft.Office.Interop.Excel.Worksheet;



            // changing the name of active sheet

            objSheet.Name = "Exported from gridview";

 // storing header part in Excel

            for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
            {

                objSheet.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;

            }


 // storing Each row and column value to excel sheet

            for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
            {

                for (int j = 0; j < dataGridView1.Columns.Count; j++)
                {

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

                }

            }

// save the application

            workbook.SaveAs("c:\\output.xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing) ;

推荐答案

文档说明你需要 12 参数正在传递''only'' 11 ），请参阅 MSDN [ ^ ]。

The documentation states it takes 12 arguments while you are passing ''only'' 11), see MSDN[^].
