Determines whether the specified objects are equal.

public:
 bool Equals(T x, T y);

public bool Equals (T x, T y);

public bool Equals (T? x, T? y);

abstract member Equals : 'T * 'T -> bool

Public Function Equals (x As T, y As T) As Boolean

Parameters

x: T

The first object of type T to compare.

y: T

The second object of type T to compare.

Returns

Boolean

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

Remarks

Implement this method to provide a customized equality comparison for type T.

Notes to Implementers

Implementations are required to ensure that if the Equals(T, T) method returns true for two objects x and y, then the value returned by the GetHashCode(T) method for x must equal the value returned for y.

The Equals(T, T) 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.
