定义

命名空间:

System.Security

程序集:

System.Security.Permissions.dll

程序集:

System.Runtime.dll

程序集:

System.Runtime.Extensions.dll

程序集:

mscorlib.dll

将权限设置为 PermissionSet，替换同一类型的任何现有权限。

public:
 System::Security::IPermission ^ SetPermission(System::Security::IPermission ^ perm);

public:
 virtual System::Security::IPermission ^ SetPermission(System::Security::IPermission ^ perm);

public System.Security.IPermission SetPermission (System.Security.IPermission perm);

public System.Security.IPermission? SetPermission (System.Security.IPermission? perm);

public virtual System.Security.IPermission SetPermission (System.Security.IPermission perm);

member this.SetPermission : System.Security.IPermission -> System.Security.IPermission

abstract member SetPermission : System.Security.IPermission -> System.Security.IPermission
override this.SetPermission : System.Security.IPermission -> System.Security.IPermission

Public Function SetPermission (perm As IPermission) As IPermission

Public Overridable Function SetPermission (perm As IPermission) As IPermission

参数

perm

IPermission

要设置的权限。

返回

IPermission

设置的权限。

例外

InvalidOperationException

从 ReadOnlyPermissionSet 调用方法。

示例

下面的代码示例演示了该方法 SetPermission 的使用。 此代码示例是为 PermissionSet 类提供的一个更大示例的一部分。

// Change the permission set using SetPermission.
ps5->SetPermission( gcnew EnvironmentPermission( EnvironmentPermissionAccess::AllAccess,"USERNAME" ) );
Console::WriteLine( "Permission set after SetPermission = {0}", ps5 );

// Change the permission set using SetPermission.
ps5.SetPermission(new EnvironmentPermission(EnvironmentPermissionAccess.AllAccess, "USERNAME"));
Console.WriteLine("Permission set after SetPermission = " + ps5.ToString());

' Change the permission set using SetPermission.
ps5.SetPermission(New EnvironmentPermission(EnvironmentPermissionAccess.AllAccess, "USERNAME"))
Console.WriteLine("Permission set after SetPermission = " & ps5.ToString())

注解

此方法从中删除同一类型 PermissionSet 的任何现有权限对象，并将其替换为 perm 参数。 如果对某个Unrestricted实现IUnrestrictedPermission的权限进行设置PermissionSet，则结果PermissionSet不再Unrestricted。

继承者说明

从PermissionSet中继承时，可以通过重写SetPermissionImpl(IPermission)方法来更改方法的行为SetPermission(IPermission)。
