public:
 override System::Web::Security::MembershipUser ^ CreateUser(System::String ^ username, System::String ^ password, System::String ^ email, System::String ^ passwordQuestion, System::String ^ passwordAnswer, bool isApproved, System::Object ^ providerUserKey, [Runtime::InteropServices::Out] System::Web::Security::MembershipCreateStatus % status);

public override System.Web.Security.MembershipUser CreateUser(string username, string password, string email, string passwordQuestion, string passwordAnswer, bool isApproved, object providerUserKey, out System.Web.Security.MembershipCreateStatus status);

override this.CreateUser : string * string * string * string * string * bool * obj * MembershipCreateStatus -> System.Web.Security.MembershipUser

Public Overrides Function CreateUser (username As String, password As String, email As String, passwordQuestion As String, passwordAnswer As String, isApproved As Boolean, providerUserKey As Object, ByRef status As MembershipCreateStatus) As MembershipUser

参数

username: String

新用户的用户名。

password: String

新用户的密码。

email: String

新用户的电子邮件地址。

passwordQuestion: String

新用户的密码问题。

passwordAnswer: String

新用户的密码答案。

isApproved: Boolean

是否批准新用户进行验证。

providerUserKey: Object

唯一 Guid 标识 SQL Server 数据库中的成员身份用户。

status: MembershipCreateStatus

其中一个 MembershipCreateStatus 值，指示用户是否已成功创建。

MembershipUser

新 MembershipUser 创建的用户的对象。如果未创建用户，此方法将 null返回。

示例

下面的代码示例为配置为使用表单身份验证和 <a0/> 的 ASP.NET 应用程序创建一个新用户。如果未成功创建用户，则会向用户显示一条消息。否则，用户将被重定向到应用程序的登录页。

注释

此示例使用Membership类调用SqlMembershipProvider指定为 defaultProvider Web.config 文件中的指定项。如果需要以类型 SqlMembershipProvider的形式访问默认提供程序，则可以强制转换 Provider 类的属性 Membership 。若要以特定提供程序类型的形式访问其他配置的提供程序，可以使用其配置的名称访问它们，Providers Membership并将它们强制转换为特定的提供程序类型。

注解

类调用 Membership 此方法，以在 ASP.NET 应用程序的配置文件中指定的 SQL Server 数据库中创建新用户。

新用户通过配置的 ApplicationName标识。

RequiresUniqueEmail如果该属性设置为 true，或者null为email参数指定了空字符串（“”），则用户创建将失败。如果将 RequiresUniqueEmail 属性设置为 true 该属性，并且为 email 参数指定的值是已配置 ApplicationName数据库中现有用户的电子邮件地址的副本，则创建用户也会失败。

用户名的最大长度为 256 个字符。电子邮件地址的最大长度为 256 个字符。密码在明文中或经过哈希处理或加密后的最大长度为 128 个字符。

导致用户创建失败的其他条件：

参数 password 是 null剪裁后的空字符串。
参数的 password 长度小于属性中指定的 MinRequiredPasswordLength 值。
参数中的 password 非字母字符数小于属性中指定的 MinRequiredNonAlphanumericCharacters 值。
该 password 参数不会在属性中 PasswordStrengthRegularExpression 传递正则表达式。
自定义密码验证代码在事件期间 ValidatingPassword 取消了用户创建。
该 RequiresQuestionAndAnswer 属性是 true ， passwordAnswer 并且参数是 null 剪裁后的空字符串。
参数 passwordAnswer 为空字符串。
参数 passwordAnswer 长度超过 128 个字符。
该 RequiresQuestionAndAnswer 属性是 true ，密码问题是剪裁后为 null 空字符串。
参数 passwordQuestion 为空字符串。
参数 passwordQuestion 长度超过 256 个字符。
参数 providerUserKey 设置为类型以外的 System.Guid对象。
该 providerUserKey 参数是现有用户密钥的副本。
该 username 参数是现有用户名的副本。

从所有字符串参数值中剪裁前导空格和尾随空格。
