writing output to directory where exe is opened from

Question

I have a form exe. now on button click i want it to save a file to where it has been opened from, e.g. if i give this exe to you and you copy it to c

Answer 1

myVar.Save(@"test.xml");

This should write test.xml to the directory your exe runs from.

Note that in case of writing to c:\ root folder might require elevated administrator permissions.

You didn't specify the type of myVar, but this might be helpful:

using System.IO;

class Program
{
    static void Main(string[] args)
    {
        File.WriteAllText("HelloWorld", "test.txt");
    }
}

This creates test.txt file with HelloWorld content, the file is saved in the executable directory.
