HostProtectionResource 枚举

定义

命名空间:

System.Security.Permissions

程序集:

System.Security.Permissions.dll

程序集:

mscorlib.dll

注意

Code Access Security is not supported or honored by the runtime.

指定若由方法或类调用，可能对宿主有害的功能的类别。

此枚举支持其成员值的按位组合。

UI	128	公开用户界面。

示例

下面的代码示例演示如何将 HostProtectionResource 枚举与属性一起使用 HostProtectionAttribute 。 此示例是为类提供的大型示例的 HostProtectionAttribute 一部分。

// Use the enumeration flags to indicate that this method exposes shared state and 
// self-affecting process management.
// Either of the following attribute statements can be used to set the 
// resource flags.
// Exit the sample when an exception is thrown.

[HostProtection(SharedState=true,SelfAffectingProcessMgmt=true)]
[HostProtection(Resources=HostProtectionResource::SharedState|
HostProtectionResource::SelfAffectingProcessMgmt)]
static void Exit( String^ Message, int Code )
{
   Console::WriteLine( "\nFAILED: {0} {1}", Message, Code );
   Environment::ExitCode = Code;
   Environment::Exit( Code );
}

// Use the enumeration flags to indicate that this method exposes 
// shared state and self-affecting process management.
// Either of the following attribute statements can be used to set the
// resource flags.
[HostProtectionAttribute(SharedState = true, 
    SelfAffectingProcessMgmt = true)]
[HostProtectionAttribute(Resources = HostProtectionResource.SharedState |
     HostProtectionResource.SelfAffectingProcessMgmt)]
private static void Exit(string Message, int Code)
{
    // Exit the sample when an exception is thrown.
    Console.WriteLine("\nFAILED: " + Message + " " + Code.ToString());
    Environment.ExitCode = Code;
    Environment.Exit(Code);
}

' Use the enumeration flags to indicate that this method exposes 
' shared state and self-affecting process management.
' Either of the following attribute statements can be used to set the 
' resource flags.
<HostProtectionAttribute(SharedState := True, _
    SelfAffectingProcessMgmt := True), _
    HostProtectionAttribute( _
    Resources := HostProtectionResource.SharedState Or _
    HostProtectionResource.SelfAffectingProcessMgmt)> _
Private Shared Sub [Exit](ByVal Message As String, ByVal Code As Integer)

    ' Exit the sample when an exception is thrown.
    Console.WriteLine((ControlChars.Lf & "FAILED: " & Message & " " & _
        Code.ToString()))
    Environment.ExitCode = Code
    Environment.Exit(Code)
End Sub

注解

此枚举由 HostProtectionAttribute 特性使用。
