Open excel file in new window (i.e. not an existing Excel instance)

Question

I'm trying to ensure that an excel file passed to my application is opened in it's own window rather than an existing Excel instance. Is there a way of telling the Process to do this? The following code always uses an existing instance if present.

Process process = new Process();
process.StartInfo.FileName = myExcelFile;
process.Start();

thanks

Matt

Try the following.

Process process = new Process();
Process.Start("Excel.exe", myExcelFile);

Other option is, if you use Interop (i.e. Microsoft.Office.Interop.Excel.dll ), you can do it as follows. This will always open the file in a new instance.

Excel.Application excelApp = new Excel.Application();
excelApp.Visible = true;
string workbookPath = (@"C:\Sample.xlsx");
Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(workbookPath,
    0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",
    true, false, 0, true, false, false);
