Best Overloaded match has some invalid arguments: string.Replace

Why is the following acceptable to Visual Studio 2005:

   string tmp = tf.InputField.Name;
   if (tmp.Replace(" ", string.Empty) == "xyz") {
      string x = string.Empty;
   }

But this produces a best overloaded match error:

   if (tf.InputField.Name.Replace(" ", string.Empty) == "xyz") {
      string x = string.Empty;
   }

tf.InputField.Name is of type string.

I've tried casting variations and using "" instead of string.Empty but still no luck.

Thanks in advance.

The problem was other variables not declared properly, I believe. Once I cleaned them up, the following statement worked"

   if (tf.InputField.Name.Replace(" ", "") == "xyz")
