注解

操作失败时CreateUser会引发类的MembershipCreateUserException实例。

备注

如果不熟悉 ASP.NET 的成员身份功能，请参阅“成员身份简介”，然后再继续操作。有关与成员身份相关的其他主题的列表，请参阅使用成员身份管理用户。

该 StatusCode 属性指示异常的原因，以便可以适当地处理它。

构造函数

MembershipCreateUserException()	初始化 MembershipCreateUserException 类的新实例。
MembershipCreateUserException(MembershipCreateStatus)	使用指定的 StatusCode 值初始化 MembershipCreateUserException 类的新实例。
MembershipCreateUserException(SerializationInfo, StreamingContext)	用提供的序列化信息和上下文初始化 MembershipCreateUserException 类的新实例。
MembershipCreateUserException(String)	初始化 MembershipCreateUserException 类的新实例，并将 Message 属性设置为所提供的 `message` 参数值。
MembershipCreateUserException(String, Exception)	初始化 MembershipCreateUserException 类的新实例，并将 Message 属性设置为提供的 `message`，将 InnerException 属性设置为提供的 `innerException`。

属性

Data	获取键/值对的集合，这些键/值对提供有关该异常的其他用户定义信息。 (继承自 Exception)
HelpLink	获取或设置指向与此异常关联的帮助文件链接。 (继承自 Exception)
HResult	获取或设置 HRESULT（一个分配给特定异常的编码数字值）。 (继承自 Exception)
InnerException	获取导致当前异常的 Exception 实例。 (继承自 Exception)
Message	获取描述当前异常的消息。 (继承自 Exception)
Source	获取或设置导致错误的应用程序或对象的名称。 (继承自 Exception)
StackTrace	获取调用堆栈上的即时框架字符串表示形式。 (继承自 Exception)
StatusCode	获取对异常原因的描述。
TargetSite	获取引发当前异常的方法。 (继承自 Exception)

方法

Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetBaseException()	当在派生类中重写时，返回 Exception，它是一个或多个并发的异常的根本原因。 (继承自 Exception)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetObjectData(SerializationInfo, StreamingContext)	使用将目标对象序列化所需的数据填充 SerializationInfo。
GetType()	获取当前实例的运行时类型。 (继承自 Exception)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	创建并返回当前异常的字符串表示形式。 (继承自 Exception)

事件

SerializeObjectState

已过时。

当异常被序列化用来创建包含有关该异常的徐列出数据的异常状态对象时会出现该问题。
