Question

I have code in C# like this.

xlWorkBook = xlApp.Workbooks.Open("data.xls", 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);

I have data.xls file where .exe are located.

When I compile and then run .exe, I’m receiving error that data.xls could not be found.

What I do wrong?

Answer 1

If your xls will always be in the same location as your .exe, you can use this to get a path that won’t be hardcoded to the build directory:

string directory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
string path = Path.Combine(directory, "data.xls");
