Why does ReSharper think that “thread.Name == null” is always false? [closed]

问题:

I am writing a helper method for conveniently setting the Name of a Thread:

public static bool TrySetName(this Thread thread, string name) {     try     {         if (thread.Name == null)         {             thread.Name = name;             return true;         }         return false;     }     catch (InvalidOperationException)     {         return false;     } } 

It's working as intended. ReSharper, however, claims that the condition is always false and the corresponding code is heuristically unreachable. That's wrong. A Thread.Name is always null until a string is assigned.

So, why does ReSharper think it is? And is there some way to tell ReSharper it isn't (other than // ReSharper disable ...)?

I'm using ReSharper 5.1.3.

This was fixed in 6+ of RS I think. See here.

It appears to be a bug in R#, fixed in v6.
