Where does StreamWriter creates text file in Mono Framework - C#

Question

I created a C# application in Visual C#. The application uses StreamWriter to write text files. The path of the text file is given application directory.

StreamWriter sw = new StreamWriter(Application.StartupPath + @"\myTExtFile.txt", true);
        sw.Write((Keys)num);
        sw.Close();

Now when I run the compiled .exe application in Windows, it runs successfully creating the text file. But when I try to run it on Mac with Mono Framework, it doesn't create the text, although it runs successfully without any error.

The application must be creating the text file, but I am unable to locate it.

Try debugging and looking at the Application.StartupPath property

or:

    var fullPath = Path.Combine (Application.StartupPath, "myTExtFile.txt");
    Console.WriteLine (fullPath);

BTW: Use Path.Combine vs. string concatenation as it is xplat-based and you do not have to deal with path separators.
