ClaimsIdentity.TryRemoveClaim Method

.NET Framework 4.5

Attempts to remove a claim from the claims identity.

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

abstract TryRemoveClaim : 
        claim:Claim -> bool  
override TryRemoveClaim : 
        claim:Claim -> bool


Type: System.Security.Claims.Claim

The claim to remove.

Return Value

Type: System.Boolean
true if the claim was successfully removed; otherwise, false.

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.

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
