WebSecurity 属性 - HasUserId


❮ WebSecurity

定义

HasUserId 属性是一个布尔值,指示当前用户在 WebSecurity 数据库中是否拥有用户 ID。

如果当前用户拥有用户 ID,则属性值为布尔 true。默认为 false


C# 和 VB 语法

WebSecurity.HasUserId

示例

C# 示例

@{
bool value;
value=WebSecurity.HasUserId;
}
<p>用户是否拥有 ID:@value</p>

VB 示例

@Code
Dim value as Boolean
value=WebSecurity.HasUserId
End Code

<p>用户是否拥有 ID:@value</p>

备注

HasUserID 属性是只读的。无法通过代码更改。

HasUserId 属性仅验证用户在 WebSecurity 数据库中是否拥有 ID。它不验证用户帐户是否有效(已确认),也不验证用户是否已登录。

使用 IsConfirmed() 方法验证用户是否已确认。

使用 IsAuthenticated 属性验证用户是否已登录。


错误和异常

如果以下情况发生,则对 WebSecurity 对象的任何访问都会引发 InvalidOperationException 异常

  • 尚未调用 InitializeDatabaseConnection() 方法
  • SimpleMembership 未初始化(或在网站配置中禁用)
