Any differnces in results?

Is there any significant difference between the following, or pitfalls to look for …in both cases setup is called before dosomethingelse from other points in the main program

 static Bitmap wxyz;
public static void setupConfig()
{ 
wxyz= new Bitmap(100,200);
wxzy.Clear();
}

public static void nowDoSomethingElse()
{
wxyz.Drawtext(blah blah)
}


 static Bitmap wxyz = new Bitmap(100, 200);
public static void setupConfig()
{ 
wxzy.Clear();
}

public static void nowDoSomethingElse()
{
wxyz.Drawtext(blah blah)
}
