範例

下列程式代碼範例顯示 方法的行為 Copy 。 這個範例是提供給 類別之較大範例的 StrongNameIdentityPermission 一部分。 此範例的最佳用法是建置和執行整個範例，並檢視其輸出。

注意

程式代碼範例旨在顯示 方法的行為，而不是示範其用法。 一般而言，安全性基礎結構會使用許可權類別的方法;它們通常不會用於應用程式。

//Copy creates and returns an identical copy of the current permission.
bool CopyDemo()
{
    bool returnValue = true;
    StrongNameIdentityPermission^ snIdPerm1;
    StrongNameIdentityPermission^ snIdPerm2;
    snIdPerm1 = gcnew StrongNameIdentityPermission(blob, "MyCompany.MyDepartment.*", gcnew Version("1.0.0.0"));
    snIdPerm2 = gcnew StrongNameIdentityPermission(PermissionState::None);

    snIdPerm2 = dynamic_cast<StrongNameIdentityPermission^>(snIdPerm1->Copy());
    Console::WriteLine("Result of copy = " + snIdPerm2->ToString() + "\n");

    return returnValue;
}

//Copy creates and returns an identical copy of the current permission.
private bool CopyDemo()

    bool returnValue = true;

    StrongNameIdentityPermission snIdPerm1, snIdPerm2;

    snIdPerm2 = (StrongNameIdentityPermission)snIdPerm1.Copy();
    Console.WriteLine("Result of copy = " + snIdPerm2.ToString() + "\n");

    return returnValue;
