ClaimsIdentity.RemoveClaim Method

.NET Framework 4.6 and 4.5

Attempts to remove a claim from the claims identity.

Namespace:  System.Security.Claims
Assembly:  mscorlib (in mscorlib.dll)

abstract RemoveClaim : 
        claim:Claim -> unit  
override RemoveClaim : 
        claim:Claim -> unit


Type: System.Security.Claims.Claim

The claim to remove.


The claim cannot be removed.

It is possible that the claim cannot be removed because it is not owned by the identity. For example, this would be the case for role claims that are owned by the principal. Unlike the TryRemoveClaim method, which returns a Boolean value that indicates whether the claim has been removed, RemoveClaim throws an exception if the claim could not be removed

The specified claim is matched by object reference (ReferenceEquals).

This method has the SecurityCritical attribute applied to control which entities can remove claims from the identity. Further down the pipe, authorization decisions are made based on the claims that are present in the Claims collection.

.NET Framework

Supported in: 4.6, 4.5

  • SecurityCriticalAttribute 

    requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
