Remarks

This class represents the roles of the current user.

Constructors

GenericPrincipal(IIdentity, String[])

Initializes a new instance of the GenericPrincipal class from a user identity and an array of role names to which the user represented by that identity belongs.

Properties

Claims

Gets a collection that contains all of the claims from all of the claims identities associated with this claims principal.

(Inherited from ClaimsPrincipal)
CustomSerializationData

Contains any additional data provided by a derived type. Typically set when calling WriteTo(BinaryWriter, Byte[]).

(Inherited from ClaimsPrincipal)
Identities

Gets a collection that contains all of the claims identities associated with this claims principal.

(Inherited from ClaimsPrincipal)
Identity

Gets the GenericIdentity of the user represented by the current GenericPrincipal.

Methods

(Inherited from ClaimsPrincipal)
Clone()

Returns a copy of this instance.

(Inherited from ClaimsPrincipal)
CreateClaimsIdentity(BinaryReader)

Creates a new claims identity.

(Inherited from ClaimsPrincipal)
Equals(Object)

Populates the SerializationInfo with data needed to serialize the current ClaimsPrincipal object.

(Inherited from ClaimsPrincipal)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
HasClaim(Predicate<Claim>)

Determines whether any of the claims identities associated with this claims principal contains a claim that is matched by the specified predicate.

(Inherited from ClaimsPrincipal)
HasClaim(String, String)

Determines whether any of the claims identities associated with this claims principal contains a claim with the specified claim type and value.

(Inherited from ClaimsPrincipal)
IsInRole(String)

Determines whether the current GenericPrincipal belongs to the specified role.

MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
ToString()
