Thread.CurrentPrincipal Thread.CurrentPrincipal Thread.CurrentPrincipal Thread.CurrentPrincipal Property

定義

ロールベースのセキュリティに関する、スレッドの現在のプリンシパルを取得または設定します。Gets or sets the thread's current principal (for role-based security).

public:
 static property System::Security::Principal::IPrincipal ^ CurrentPrincipal { System::Security::Principal::IPrincipal ^ get(); void set(System::Security::Principal::IPrincipal ^ value); };
public static System.Security.Principal.IPrincipal CurrentPrincipal { get; set; }
member this.CurrentPrincipal : System.Security.Principal.IPrincipal with get, set
Public Shared Property CurrentPrincipal As IPrincipal

プロパティ値

セキュリティ コンテキストを表す IPrincipal 値。An IPrincipal value representing the security context.

例外

呼び出し元に、プリンシパルを設定するために必要なアクセス許可がありません。The caller does not have the permission required to set the principal.

次のコード例では、設定およびスレッドのプリンシパルを取得する方法を示します。The following code example shows how to set and retrieve the principal of a thread.

using namespace System;
using namespace System::Security;
using namespace System::Security::Permissions;
using namespace System::Security::Principal;
using namespace System::Threading;

int main()
{
   array<String^>^rolesArray = {"managers","executives"};
   try
   {
      
      // Set the principal to a new generic principal.
      Thread::CurrentPrincipal = gcnew GenericPrincipal( gcnew GenericIdentity( "Bob","Passport" ),rolesArray );
   }
   catch ( SecurityException^ secureException ) 
   {
      Console::WriteLine( "{0}: Permission to set Principal "
      "is denied.", secureException->GetType()->Name );
   }

   IPrincipal^ threadPrincipal = Thread::CurrentPrincipal;
   Console::WriteLine( "Name: {0}\nIsAuthenticated: {1}"
   "\nAuthenticationType: {2}", threadPrincipal->Identity->Name, threadPrincipal->Identity->IsAuthenticated.ToString(), threadPrincipal->Identity->AuthenticationType );
}

        try
        {
            // Set the principal to a new generic principal.
            Thread.CurrentPrincipal = 
                new GenericPrincipal(new GenericIdentity(
                "Bob", "Passport"), rolesArray);
        }
        catch(SecurityException secureException)
        {
            Console.WriteLine("{0}: Permission to set Principal " +
                "is denied.", secureException.GetType().Name);
        }

        IPrincipal threadPrincipal = Thread.CurrentPrincipal;
        Console.WriteLine("Name: {0}\nIsAuthenticated: {1}" +
            "\nAuthenticationType: {2}", 
            threadPrincipal.Identity.Name, 
            threadPrincipal.Identity.IsAuthenticated,
