有一个构造函数，它将为您完成:

There is a constructor, which will do it for you:

public ClaimsPrincipal(IEnumerable<ClaimsIdentity> identities)

但是，其语义是不确定的.到目前为止，Microsoft尚未使用过它，而且我从未能够将其序列化为可互操作的SAML令牌……我不确定SesAM会如何使用它.

However, the semantics of this are undefined. Microsoft hasn't used it so far and I was never able to serialize it into an interoperable SAML token...... I am not sure what SesAM will do with it.
