SamlAttribute Class

Represents an attribute that is associated with the subject of a SamlAttributeStatement.

Namespace:  System.IdentityModel.Tokens
Assembly:  System.IdentityModel (in System.IdentityModel.dll)

public class SamlAttribute

The SamlAttribute class corresponds to the <saml:Attribute> XML element that is defined in the OASIS SAML 1.1 specification.

A SamlAttribute instance contains PossessProperty claims for the subject of a SamlAttributeStatement. For example, a SamlAttribute might contain an Over21 claim, whose type would be specified in the Namespace property and whose resource would be specified as a member of the collection in the AttributeValues property. When the CreatePolicy method is called, this Over21 claim is added to the authorization policy that is returned by returned from by the SamlAttributeStatement. When the AttributeValues property contains multiple elements then one claim is returned for each element.

SamlAttribute position in the SAML object hierarchy is:

        // Copy Name claims from the incoming credentials into the set of claims to be issued.
        IEnumerable<Claim> nameClaims = claimSet.FindClaims(ClaimTypes.Name, Rights.PossessProperty);
        if (nameClaims != null)
        {
            foreach (Claim nameClaim in nameClaims)
            {
