ClaimSet Class

Represents the collection of claims that are associated with an entity.

Namespace: System.IdentityModel.Claims
Assembly: System.IdentityModel (in system.identitymodel.dll)

public abstract class ClaimSet : IEnumerable<Claim>, IEnumerable
public abstract class ClaimSet implements IEnumerable<Claim>, 
	IEnumerable
public abstract class ClaimSet implements IEnumerable<Claim>, 
	IEnumerable
Not applicable.

After the ClaimSet class has been created, it cannot be changed.

Examining the content of a ClaimSet for particular types of claims is a common task when using claim-based authorization. To examine a ClaimSet for the presence of particular claims, use the FindClaims method. The method provides better performance than iterating directly over the ClaimSet.

public class MyServiceAuthorizationManager : ServiceAuthorizationManager
{
 
   protected override bool CheckAccessCore(OperationContext operationContext)
    {                
        // Extract the action URI from the OperationContext. Match this against the claims
        // in the AuthorizationContext.

        string action = operationContext.RequestContext.RequestMessage.Headers.Action;
        Console.WriteLine("action: {0}", action);

        // Iterate through the various claim sets in the AuthorizationContext.
        foreach(ClaimSet cs in operationContext.ServiceSecurityContext.AuthorizationContext.ClaimSets)
        {
            // Examine only those claim sets issued by System.
            if (cs.Issuer == ClaimSet.System)
            {
                // Iterate through claims of type "http://example.org/claims/allowedoperation".
                foreach (Claim c in cs.FindClaims("http://example.org/claims/allowedoperation", 
                    Rights.PossessProperty))
                {
                    // Write the claim resource to the console.
                    Console.WriteLine("resource: {0}", c.Resource.ToString());

                    // If the claim resource matches the action URI then return true to allow access.
                    if (action == c.Resource.ToString())
                        return true;
                }
            }
        }
        
        // If this point is reached, return false to deny access.
        return false;                 
    }
