Determines whether the specified objects are equal.
Assembly: mscorlib (in mscorlib.dll)
x and y are of different types and neither one can handle comparisons with the other.
Implement this method to provide a customized equality comparison for objects.Notes to Implementers
The method is reflexive, symmetric, and transitive. That is, it returns true if used to compare an object with itself; true for two objects x and y if it is true for y and x; and true for two objects x and z if it is true for x and y and also true for y and z.
Implementations are required to ensure that if the method returns true for two objects x and y, then the value returned by the GetHashCode method for x must equal the value returned for y.
The following code example demonstrates the implementation of a case-insensitive IEqualityComparer. In this example, the CaseInsensitiveComparer.Compare method is used to determine whether two objects are equal, based on the provided CultureInfo.
