GacInstalled 类

定义

命名空间:

System.Security.Policy

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.

确认一个代码程序集在全局程序集缓存 (GAC) 中以策略评估证据的形式产生。 此类不能被继承。

示例

下面的代码示例演示了类 GacInstalled 的使用。

using namespace System;
using namespace System::Security::Policy;
using namespace System::Security;
using namespace System::Security::Permissions;

[STAThread]
int main()
{

    GacInstalled ^ myGacInstalled = gcnew GacInstalled;

    array<Object^>^hostEvidence = {myGacInstalled};
    array<Object^>^assemblyEvidence = {};
    Evidence^ myEvidence = gcnew Evidence( hostEvidence,assemblyEvidence );
    GacIdentityPermission ^ myPerm = dynamic_cast<GacIdentityPermission^>
        (myGacInstalled->CreateIdentityPermission( myEvidence ));
    Console::WriteLine( myPerm->ToXml() );

    GacInstalled ^ myGacInstalledCopy = 
        dynamic_cast<GacInstalled^>(myGacInstalled->Copy());
    bool result = myGacInstalled->Equals( myGacInstalledCopy );

    Console::WriteLine( "Hashcode = {0}", myGacInstalled->GetHashCode() );

    Console::WriteLine( myGacInstalled->ToString() );
}

using System;
using System.Security.Policy;

注解

注意

代码访问安全性 (CAS) 已在所有版本的 .NET Framework 和 .NET 中弃用。 使用与 CAS 相关的 API 时，最新版本的 .NET 不遵循 CAS 注释并生成错误。 开发人员应寻求实现安全任务的替代方法。

证据的存在GacInstalled在授予集中产生。GacIdentityPermission Demand GacIdentityPermission如果有，则GacIdentityPermission与GacInstalled证据对应的是与所需权限相比较的。

构造函数
