注解

重写 UserNameSecurityTokenAuthenticator 类，以便根据用户名和密码对安全令牌进行身份验证。

Windows Communication Foundation 附带以下类，这些类支持对安全令牌进行身份验证 UserNameSecurityToken 。

类型	描述
CustomUserNameSecurityTokenAuthenticator	使应用程序可以为用户名和密码提供自定义身份验证方案。身份验证方案是使用派生自 UserNamePasswordValidator 类的类提供的。
WindowsUserNameSecurityTokenAuthenticator	将用户名和密码作为 Windows 帐户进行身份验证。

大多数自定义身份验证方案可以使用 CustomUserNameSecurityTokenAuthenticator 类和实现派生自 UserNamePasswordValidator 类的类。但是，如果需要额外的灵活性，则可以从 UserNameSecurityTokenAuthenticator 类派生类并重写 ValidateUserNamePasswordCore 方法。

构造函数

UserNameSecurityTokenAuthenticator()

初始化 UserNameSecurityTokenAuthenticator 类的新实例。

方法

CanValidateToken(SecurityToken)	获取一个值，该值指示指定的安全令牌是否可由该安全令牌身份验证器进行验证。 (继承自 SecurityTokenAuthenticator)
CanValidateTokenCore(SecurityToken)	获取一个值，该值指示指定的安全令牌是否可由该安全令牌身份验证器进行验证。
Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示当前对象的字符串。 (继承自 Object)
ValidateToken(SecurityToken)	对指定的安全令牌进行身份验证，并返回该安全令牌的授权策略集。 (继承自 SecurityTokenAuthenticator)
ValidateTokenCore(SecurityToken)	对指定的安全令牌进行身份验证，并返回该安全令牌的授权策略集。
ValidateUserNamePasswordCore(String, String)	如果在派生类中重写，则对指定的用户名和密码进行身份验证，并且返回 UserNameSecurityToken 安全令牌的授权策略集。
