C-sharp : Incorrect comparison with NULL

Classification

CWE
CWE-754

Overview



The application compares the object to null using Equals(). Expression obj.Equals(null) always returns false.

According to msdn, all implementations of Equals() must not throw exceptions; they should always return a value. For example, if obj is null, the Equals() method should return false instead of throwing an ArgumentNullException.
