SecurityPermission 构造函数

定义

命名空间:

System.Security.Permissions

程序集:

System.Security.Permissions.dll

包:

System.Security.Permissions v8.0.0

初始化 SecurityPermission 类的新实例。

重载

SecurityPermission(PermissionState)	根据指定，使用受限制或不受限制的权限初始化 SecurityPermission 类的新实例。
SecurityPermission(SecurityPermissionFlag)	初始化具有指定标志初始设置状态的 SecurityPermission 类的一个新实例。

SecurityPermission(PermissionState)

Source:

SecurityPermission.cs

根据指定，使用受限制或不受限制的权限初始化 SecurityPermission 类的新实例。

public:
 SecurityPermission(System::Security::Permissions::PermissionState state);

public SecurityPermission (System.Security.Permissions.PermissionState state);

new System.Security.Permissions.SecurityPermission : System.Security.Permissions.PermissionState -> System.Security.Permissions.SecurityPermission

Public Sub New (state As PermissionState)

参数

state

PermissionState

PermissionState 值之一。

例外

ArgumentException

state 参数不是 PermissionState 的有效值。

注解

创建完全受限 (None) 或 Unrestricted 对所有安全权限的访问权限。

SecurityPermission(SecurityPermissionFlag)

Source:

SecurityPermission.cs

初始化具有指定标志初始设置状态的 SecurityPermission 类的一个新实例。

public:
 SecurityPermission(System::Security::Permissions::SecurityPermissionFlag flag);

public SecurityPermission (System.Security.Permissions.SecurityPermissionFlag flag);

new System.Security.Permissions.SecurityPermission : System.Security.Permissions.SecurityPermissionFlag -> System.Security.Permissions.SecurityPermission

Public Sub New (flag As SecurityPermissionFlag)

参数

flag

SecurityPermissionFlag

权限的初始状态使用由 SecurityPermissionFlag 定义的任何权限位的位 OR 组合来表示。

例外

ArgumentException

flag 参数不是 SecurityPermissionFlag 的有效值。

示例

下面的代码示例演示如何使用 SecurityPermission 构造函数创建类的 SecurityPermission 实例，这些实例用于要求安全权限。 有关完整的代码示例，请参阅 SecurityPermissionAttribute(SecurityAction) 构造函数。
