ProcessModule.EntryPointAddress Propriété

Définition

Espace de noms:

System.Diagnostics

Assembly:

System.Diagnostics.Process.dll

Source:

ProcessModule.cs

Obtient l'adresse mémoire de la fonction qui s'exécute lorsque le système charge et exécute le module.

public:
 property IntPtr EntryPointAddress { IntPtr get(); };

public IntPtr EntryPointAddress { get; }

member this.EntryPointAddress : nativeint

Public ReadOnly Property EntryPointAddress As IntPtr

Valeur de propriété

IntPtr

nativeint

Point d'entrée du module.

Exemples

L'exemple de code suivant crée un processus pour l'application Notepad.exe. Le code itère au sein de la classe ProcessModuleCollection afin d’obtenir un objet ProcessModule pour chaque module de la collection. Les propriétés ModuleName et EntryPointAddress permettent d'afficher le nom et l'adresse du point d'entrée de chaque module.

Process^ myProcess = gcnew Process;

// Get the process start information of notepad.
ProcessStartInfo^ myProcessStartInfo = gcnew ProcessStartInfo( "notepad.exe" );

// Assign 'StartInfo' of notepad to 'StartInfo' of 'myProcess' object.
myProcess->StartInfo = myProcessStartInfo;

// Create a notepad.
myProcess->Start();
System::Threading::Thread::Sleep( 1000 );
ProcessModule^ myProcessModule;

// Get all the modules associated with 'myProcess'.
ProcessModuleCollection^ myProcessModuleCollection = myProcess->Modules;
Console::WriteLine( "Entry point addresses of the modules associated with 'notepad' are:" );

// Display the 'EntryPointAddress' of each of the modules.
for ( int i = 0; i < myProcessModuleCollection->Count; i++ )
{
   myProcessModule = myProcessModuleCollection[ i ];
   Console::WriteLine( "{0} : {1}", myProcessModule->ModuleName, myProcessModule->EntryPointAddress );
}
myProcessModule = myProcess->MainModule;
Console::WriteLine( "The process's main module's EntryPointAddress is: {0}", myProcessModule->EntryPointAddress );
myProcess->CloseMainWindow();

using (Process myProcess = new Process())
{
    // Get the process start information of notepad.
    ProcessStartInfo myProcessStartInfo = new ProcessStartInfo("notepad.exe");
    // Assign 'StartInfo' of notepad to 'StartInfo' of 'myProcess' object.
    myProcess.StartInfo = myProcessStartInfo;
    // Create a notepad.
    myProcess.Start();
    System.Threading.Thread.Sleep(1000);
    ProcessModule myProcessModule;
    // Get all the modules associated with 'myProcess'.
    ProcessModuleCollection myProcessModuleCollection = myProcess.Modules;
    Console.WriteLine("Entry point addresses of the modules "
        + "associated with 'notepad' are:");
    // Display the 'EntryPointAddress' of each of the modules.
    for (int i = 0; i < myProcessModuleCollection.Count; i++)
    {
        myProcessModule = myProcessModuleCollection[i];
        Console.WriteLine(myProcessModule.ModuleName + " : "
            + myProcessModule.EntryPointAddress);
    }
    // Get the main module associated with 'myProcess'.
    myProcessModule = myProcess.MainModule;
    Console.WriteLine("The process's main module's EntryPointAddress is: "
        + myProcessModule.EntryPointAddress);
    myProcess.CloseMainWindow();
}

Using myProcess As New Process()
    ' Get the process start information of notepad.
    Dim myProcessStartInfo As New ProcessStartInfo("notepad.exe")
    ' Assign 'StartInfo' of notepad to 'StartInfo' of 'myProcess' object.
    myProcess.StartInfo = myProcessStartInfo
    ' Create a notepad.
    myProcess.Start()
    System.Threading.Thread.Sleep(1000)
    Dim myProcessModule As ProcessModule
    ' Get all the modules associated with 'myProcess'.
    Dim myProcessModuleCollection As ProcessModuleCollection = myProcess.Modules
    Console.WriteLine("Entry point addresses of the modules " +
                   "associated with 'notepad' are:")
    ' Display the 'EntryPointAddress' of each of the modules.
    Dim i As Integer
    For i = 0 To myProcessModuleCollection.Count - 1
        myProcessModule = myProcessModuleCollection(i)
        Console.WriteLine(myProcessModule.ModuleName + " : " +
                                myProcessModule.EntryPointAddress.ToString())
    Next i
    ' Get the main module associated with 'myProcess'.
    myProcessModule = myProcess.MainModule
    Console.WriteLine("The process's main module's EntryPointAddress is: " +
                         myProcessModule.EntryPointAddress.ToString())
    myProcess.CloseMainWindow()
End Using

Remarques

Le point d'entrée du module est l'emplacement de la fonction appelée pendant le démarrage du processus, le démarrage du thread, l'arrêt du processus et l'arrêt du thread. Même si le point d'entrée ne représente pas l'adresse de la fonction DllMain, il devrait être assez proche pour la plupart des applications.

Notes

En raison des modifications apportées à la façon dont Windows charge les assemblys, EntryPointAddress retourne toujours 0 sur Windows 8 ou Windows 8.1 et ne doit pas être utilisé pour ces plateformes.
