Question

In a C# program, I have an error check that gets repeated a lot:

try 
{
  File.Move(searchfolder + question1 +"_"+ filestring +".txt", 
            searchfolder + question1 +".txt");
}
catch (Exception ex) 
{
  File.AppendAllText(adminfolder + question1 +"_l.txt", "!"); 
  side.Value = Convert.ToString(ex) + "[Check-In error at "
                               + Convert.ToString(MYLINE) +"] "+ side.Value;
}

MYLINE is some number, and MYLINE is the only thing that changes across my program.

So a normal C++ #define macro would make this much simpler to work with (I would just write the full “#define CHECKIN(MYLINE) …” once at the top of the program).

How would a pro deal with this in C#?

Well, perhaps, but since C# doesn’t have a concept of macros… just use a method:

static class FileMover
{
    public static void MoveMyFile(string myline)
    {
        // your existing code here
    }
}

On a side note, there is glaring problem in your code. In your catch block you call File.AppendAllText()… which, of course, can throw an exception as well. You need to account for that.
