如何在不显示保存对话框的情况下保存Excel文件

您好，我尝试用自动保存路径的方式保存excel文件，但是当我保存它时，我会弹出另存为该代码的地方。我如何用我异常需要的路径保存此文件

      Microsoft.Office.Interop.Excel.Application oXL;
                Microsoft.Office.Interop.Excel._Workbook oWB;
                Microsoft.Office.Interop.Excel._Worksheet oSheet;
                Microsoft.Office.Interop.Excel.Range oRng;
                object misvalue = System.Reflection.Missing.Value;
                try
                {
                    //Start Excel and get Application object.
                    oXL = new Microsoft.Office.Interop.Excel.Application();
                    oXL.Visible = true;

                    //Get a new workbook.
                    oWB = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Add(""));
                    oSheet = (Microsoft.Office.Interop.Excel._Worksheet)oWB.ActiveSheet;

                    //Add table headers going cell by cell.
                    oSheet.Cells[1, 1] = "First Name";
                    oSheet.Cells[1, 2] = "Last Name";
                    oSheet.Cells[1, 3] = "Full Name";
                    oSheet.Cells[1, 4] = "Salary";

                    //Format A1:D1 as bold, vertical alignment = center.
                    oSheet.get_Range("A1", "D1").Font.Bold = true;
                    oSheet.get_Range("A1", "D1").VerticalAlignment =
                        Microsoft.Office.Interop.Excel.XlVAlign.xlVAlignCenter;

                    // Create an array to multiple values at once.
                    string[,] saNames = new string[5, 2];

                    saNames[0, 0] = "John";
                    saNames[0, 1] = "Smith";
                    saNames[1, 0] = "Tom";
                    saNames[1, 1] = "Brown";

                    oXL.Visible = true;
                    oXL.UserControl = true;

oWB.SaveAs("c://Vova/test34545.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing,
false, false, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
oWB.Close();
