EqualityComparer<T>.Equals Method (T, T)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
When overridden in a derived class, determines whether two objects of type T are equal.
Namespace: System.Collections.Generic
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public MustOverride Function Equals ( _
x As T, _
y As T _
) As Boolean
public abstract bool Equals(
T x,
T y
)
Return Value
Type: System.Boolean
true if the specified objects are equal; otherwise, false.
Implements
Remarks
The Equals 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.
Notes to Inheritors
Implementations are required to ensure that if the Equals 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.
