Running an Excel Macro via C#: Run a macro from one workbook on another?

I found a solution that I'd like to share. First, I removed the bit where I opened Worksheet01. I then had my automated script save the .CSV to My Documents. I then used the code I had to open Worksheet01 to open the downloaded file. The key thing at this point is that Worksheet01 is in the Documents folder with Worksheet02. Lastly I used the code to run the macro from Worksheet01, which runs on Worksheet02.

    public void WebTest_CodedStep()
    {
        // Object for missing (or optional) arguments.
        object oMissing = System.Reflection.Missing.Value;

        // Create an instance of Microsoft Excel
        Excel.ApplicationClass oExcel = new Excel.ApplicationClass();

        // Make it visible
        oExcel.Visible = true;

        // Define Workbooks
        Excel.Workbooks oBooks = oExcel.Workbooks;
        Excel._Workbook oBook = null;

        // Get the file path
        string path = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
        path = path + "\\Worksheet02.csv";

        //Open the file, using the 'path' variable
        oBook = oBooks.Open(path, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing,  oMissing, oMissing, oMissing, oMissing, oMissing, oMissing);

        // Run the macro, "First_Macro"
        RunMacro(oExcel, new Object[]{"Worksheet01.xlsm!First_Macro"});

        // Quit Excel and clean up.
        oBook.Close(false, oMissing, oMissing);
        System.Runtime.InteropServices.Marshal.ReleaseComObject (oBook);
        oBook = null;
        System.Runtime.InteropServices.Marshal.ReleaseComObject (oBooks);
        oBooks = null;
        oExcel.Quit();
        System.Runtime.InteropServices.Marshal.ReleaseComObject (oExcel);
        oExcel = null;

        //Garbage collection
        GC.Collect();
    }

    private void RunMacro(object oApp, object[] oRunArgs)
    {
        oApp.GetType().InvokeMember("Run", System.Reflection.BindingFlags.Default | System.Reflection.BindingFlags.InvokeMethod, null, oApp, oRunArgs);
    }

I ran this C# VSTO code to invoke a VBA Macro, this is the syntax I use:

this.Application.Run("mymacro");

Edit:

Macros are Workbook wide, perhaps you need to make Sheet2 the active worksheet before running the macro, eg:

foreach (Worksheet worksheet in workbook.Sheets.ComLinq<Worksheet>())
{
    if (worksheet.Name == "Sheet2") worksheet.Activate();
}
