Returns

bool

true if the current object is equal to the other parameter; otherwise, false.

Equals(object)

Determines whether the specified object is equal to the current object.

public override bool Equals(object obj)

Parameters

obj object

The object to compare with the current object.

Returns

bool

true if the specified object is equal to the current object; otherwise, false.
