Namespace:  System.Collections.Generic
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Private Function Equals ( _
    x As Object, _
    y As Object _
) As Boolean Implements IEqualityComparer.Equals

bool IEqualityComparer.Equals(
    Object x,
    Object y
)

Parameters

Return Value

Type: System.Boolean
true if the specified objects are equal; otherwise, false.

Implements

IEqualityComparer.Equals(Object, Object)

Exceptions

Exception Condition
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 nulla null reference (Nothing in Visual Basic) is allowed and does not generate an exception.
