PermissionSet.Union(PermissionSet) 方法

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

创建 PermissionSet，它是当前的 PermissionSet 和指定的 PermissionSet 的并集。

public:
 System::Security::PermissionSet ^ Union(System::Security::PermissionSet ^ other);

public:
 virtual System::Security::PermissionSet ^ Union(System::Security::PermissionSet ^ other);

public System.Security.PermissionSet Union (System.Security.PermissionSet other);

public System.Security.PermissionSet? Union (System.Security.PermissionSet? other);

public virtual System.Security.PermissionSet Union (System.Security.PermissionSet other);

member this.Union : System.Security.PermissionSet -> System.Security.PermissionSet

abstract member Union : System.Security.PermissionSet -> System.Security.PermissionSet
override this.Union : System.Security.PermissionSet -> System.Security.PermissionSet

Public Function Union (other As PermissionSet) As PermissionSet

Public Overridable Function Union (other As PermissionSet) As PermissionSet

参数

other

PermissionSet

与当前的 PermissionSet 形成并集的权限集。

返回

PermissionSet

一个新权限集，它表示当前 PermissionSet 与指定 PermissionSet 的并集。

示例

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

// Display the union of two permission sets.
PermissionSet^ ps5 = ps3->Union( ps4 );
Console::WriteLine( "The union of permission set 3 and permission set 4 = {0}", ps5 );

// Display the union of two permission sets.
PermissionSet ps5 = ps3.Union(ps4);
Console.WriteLine("The union of permission set 3 and permission set 4 = "
    + ps5.ToString());

' Display the union of two permission sets.
Dim ps5 As PermissionSet = ps3.Union(ps4)
Console.WriteLine("The union of permission set 3 and permission set 4 = " & ps5.ToString())

注解

调用 Union 的结果是表示 PermissionSet 当前 PermissionSet 表示的所有操作，以及指定 PermissionSet表示的所有操作。 如果任一设置， Unrestricted则联合也是 Unrestricted 。
