ServiceController.DisplayName プロパティ

サービスの表示名を取得または設定します。

名前空間: System.ServiceProcess
アセンブリ: System.ServiceProcess (system.serviceprocess.dll 内)
構文

Visual Basic (宣言)

Public Property DisplayName As
 String

Visual Basic (使用法)

Dim instance As ServiceController
Dim value As String

value = instance.DisplayName

instance.DisplayName = value

public string DisplayName { get;
 set; }

C++

public:
property String^ DisplayName {
    String^ get ();
    void set (String^ value);
}

/** @property */
public String get_DisplayName ()

/** @property */
public void set_DisplayName (String value)

JScript

public function get DisplayName
 () : String

public function set DisplayName
 (value : String)

プロパティ値
サービスの表示名。サービスを識別するために使用します。

例外

例外の種類	条件
ArgumentNullException	DisplayName が null 参照 (Visual Basic では Nothing) です。
Win32Exception	システム API へのアクセス中にエラーが発生しました。

解説

DisplayName を空の文字列 ("") に設定できますが、プロパティを null 参照 (Visual Basic では Nothing) に設定すると、例外がスローされます。

使用例

ServiceController クラスを使用して、Event Log サービスに依存するサービスのセットを表示する例を次に示します。

Visual Basic

Dim sc As New ServiceController("Event
 Log")
Dim scServices As ServiceController() = sc.DependentServices

' Display the list of services dependent on the Event Log service.
If scServices.Length = 0 Then
   Console.WriteLine("There are no services dependent on {0}",
 sc.ServiceName)
Else
   Console.WriteLine("Services dependent on {0}:",
 sc.ServiceName)
   
   Dim scTemp As ServiceController
   For Each scTemp In  scServices
      Console.WriteLine(" {0}", scTemp.DisplayName)
   Next scTemp
End If

ServiceController sc =  new ServiceController("Event Log");
ServiceController[] scServices = sc.DependentServices;
       
// Display the list of services dependent on the Event Log service.
if (scServices.Length == 0)
{
   Console.WriteLine("There are no services dependent on {0}", 
                      sc.ServiceName);
}
else 
{
   Console.WriteLine("Services dependent on {0}:",
                      sc.ServiceName);

   foreach (ServiceController scTemp in scServices)
   {
      Console.WriteLine(" {0}", scTemp.DisplayName);
   }
}

C++

ServiceController^ sc = gcnew ServiceController(  "Event Log" );
array<ServiceController^>^scServices = nullptr;
if ( sc )
{
   scServices = sc->DependentServices;
}

if ( sc && scServices )
{
   // Display the list of services dependent on the Event Log service.
   if ( scServices->Length == 0 )
   {
      Console::WriteLine(  "There are no services dependent on {0}", sc->ServiceName
 );
   }
   else
   {
      Console::WriteLine(  "Services dependent on {0}:", sc->ServiceName
 );
      for each (ServiceController^ scTemp in
 scServices)
      {
         Console::WriteLine(" {0}", scTemp->DisplayName);
      }
   }
}

ServiceController sc = new ServiceController("Event Log");
ServiceController scServices[] = sc.get_DependentServices();
// Display the list of services dependent on the Event Log service.
if (scServices.get_Length() == 0) {
    Console.WriteLine("There are no services dependent on {0}",
        sc.get_ServiceName());
}
else {
    Console.WriteLine("Services dependent on {0}:", 
        sc.get_ServiceName());
    ServiceController scTemp = new ServiceController();
    for  (int iCtr = 0; iCtr < scServices.get_Length();
 iCtr++) {
        scTemp = scServices[iCtr];
        Console.WriteLine(" {0}", scTemp.get_DisplayName());
    }
}
