Build a valid file name

I could not find anything in AX building a true valid file name. That is, just the name of the file itself, not the path.

So I came up with this:

public static Filename buildValidFilename(str  _filename)
{
    #xppTexts
    #define.LeftSquareBracket('[')
    #define.RightSquareBracket(']')

    Filename  validFilename;
    str       invalidFileNameChars;

    new InteropPermission(InteropKind::ClrInterop).assert();

    // Remove the characters that .NET defines as invalid
    invalidFileNameChars = new System.String(System.IO.Path::GetInvalidFileNameChars());
    validFilename = System.Text.RegularExpressions.Regex::Replace(_filename, #LeftSquareBracket + invalidFileNameChars + #RightSquareBracket, #emptyString);

    // Remove the characters that .NET doesn't remove
    invalidFileNameChars =  @'"\\/:*?\<>|' + "'";
    validFilename = System.Text.RegularExpressions.Regex::Replace(validFilename, #LeftSquareBracket + invalidFileNameChars + #RightSquareBracket, #emptyString);

    CodeAccessPermission::revertAssert();

    return validFilename;
}
