Apply attribute to property get/set methods via batch file.

Question

I'm trying to automate the generation and cleanup of partial classes created using the .net framework's XSD too. My main problem is that [System.Diagnostics.DebuggerStepThroughAttribute()] affects the code in my partial class as well as the automatically generated one. I can delete the offending attribute in the same batch file that I use to create the files.

However I don't want to be stepping into all of the autogenerated file's properties. I can stop the debugger from entering each property by applying [System.Diagnostics.DebuggerStepThrough()] to the get and set methods. Can I do this via a batch file? without needing to install/configure a third party scripting language to do the text processing?

Example property with attributes added:

public string FileFormatVersion
{
    [System.Diagnostics.DebuggerStepThrough()]
    get { 
    return this.fileFormatVersionField;
    }
    [System.Diagnostics.DebuggerStepThrough()]
    set
    {
        this.fileFormatVersionField = value;
    }
}

Answer 1

I know you'd like to use a .bat file but I really think python or another scripting language is your best bet here.

Answer 2

setlocal enabledelayedexpansion
set outfile=%1.copy
del "%outfile%"
for /f "delims=" %%x in (%1) do (
    set line=%%x
    if "!line: =!"=="get{" (
     echo [System.Diagnostics.DebuggerStepThrough^(^)]>>%outfile%
    )
    if "!line: =!"=="set{" (
     echo [System.Diagnostics.DebuggerStepThrough^(^)]>>%outfile%
    )
    echo.%%x>>%outfile%
)

This is simplistic, and won't handle cases like properties that already have the attribute added. It also might choke on some lines of code, but I haven't found a line that does yet.

[Edit] Made the changes mentioned below, except for the extra echo indentation (would just look ugly on this page).
