Returns a value that indicates whether this instance is equal to a specified object.

Namespace:   System.Data
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

public override bool Equals(
	object obj
)

Parameters

obj
Type: System.Object

An Object to compare with this instance.

Return Value

Type: System.Boolean

true if this instance and obj have equal values; otherwise, false.

Temporary keys have different comparison semantics than permanent keys:

  • Temporary keys use reference equality. That is, two references to the exact same temporary EntityKey instance are equal but no other EntityKey instances are equal.

  • Permanent keys determine equality based on the values of the contained key properties and the EntitySet. That is, you can have two separate EntityKey instances that are equal if their EntitySet objects are the same and their key values are equal.

In addition, temporary keys have no EntitySet or key values, but permanent keys do.
