Remarks

Use the ClaimTypes class to search for a particular type of claim in a ClaimSet or to create a claim. To search for a particular type of claim in a ClaimSet, use the FindClaims(String, String) method and use the properties of this class to specify the claim type for the claimType parameter. When the constructor for the Claim class is used to create a new claim, use the properties of the ClaimTypes class to specify the claimType parameter. For many of the claim types, the Claim class has static properties that return a claim of a specific type. For instance, the CreateHashClaim(Byte[]) method returns a claim using the Hash claim type.
