Determines whether the specified objects are equal.

 virtual bool System.Collections.IEqualityComparer.Equals(System::Object ^ x, System::Object ^ y) = System::Collections::IEqualityComparer::Equals;

bool IEqualityComparer.Equals(object x, object y);

abstract member System.Collections.IEqualityComparer.Equals : obj * obj -> bool
override this.System.Collections.IEqualityComparer.Equals : obj * obj -> bool

Function Equals (x As Object, y As Object) As Boolean Implements IEqualityComparer.Equals

Parameters

x: Object

The first object to compare.

y: Object

The second object to compare.

Returns

Boolean

true if the specified objects are equal; otherwise, false.

Implements

Equals(Object, Object)

Exceptions

ArgumentException

x or y is of a type that cannot be cast to type T.

Remarks

This method is a wrapper for the Equals(T, T) method, so obj must be cast to the type specified by the generic argument T of the current instance. If it cannot be cast to T, an ArgumentException is thrown.

Comparing null is allowed and does not generate an exception.
