Assembly.GetExecutingAssembly Metodo

Definizione

Spazio dei nomi:

System.Reflection

Assembly:

System.Runtime.dll

Origine:

Assembly.CoreCLR.cs

Ottiene l'assembly che contiene il codice attualmente in esecuzione.

public:
 static System::Reflection::Assembly ^ GetExecutingAssembly();

public static System.Reflection.Assembly GetExecutingAssembly ();

static member GetExecutingAssembly : unit -> System.Reflection.Assembly

Public Shared Function GetExecutingAssembly () As Assembly

Restituisce

Assembly

Assembly che contiene il codice attualmente in esecuzione.

Esempio

Nell'esempio seguente viene utilizzata la Type.Assembly proprietà per ottenere l'assembly attualmente in esecuzione in base a un tipo contenuto nell'assembly. Chiama anche il GetExecutingAssembly metodo per mostrare che restituisce un Assembly oggetto che rappresenta lo stesso assembly.

using namespace System;
using namespace System::Reflection;

ref class Example
{};

void main()
{
   // Get the assembly from a known type in that assembly.
   Type^ t = Example::typeid;
   Assembly^ assemFromType = t->Assembly;
   Console::WriteLine("Assembly that contains Example:");
   Console::WriteLine("   {0}\n", assemFromType->FullName);

   // Get the currently executing assembly.
   Assembly^ currentAssem = Assembly::GetExecutingAssembly();
   Console::WriteLine("Currently executing assembly:");
   Console::WriteLine("   {0}\n", currentAssem->FullName);

   Console::WriteLine("The two Assembly objects are equal: {0}",
                      assemFromType->Equals(currentAssem));
}
// The example displays the following output:
//    Assembly that contains Example:
//       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
//
//    Currently executing assembly:
//       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
//
//    The two Assembly objects are equal: True

using System;
using System.Reflection;

class Example
{
   static void Main()
   {
      // Get the assembly from a known type in that assembly.
      Type t = typeof(Example);
      Assembly assemFromType = t.Assembly;
      Console.WriteLine("Assembly that contains Example:");
      Console.WriteLine("   {0}\n", assemFromType.FullName);

      // Get the currently executing assembly.
      Assembly currentAssem = Assembly.GetExecutingAssembly();
      Console.WriteLine("Currently executing assembly:");
      Console.WriteLine("   {0}\n", currentAssem.FullName);

      Console.WriteLine("The two Assembly objects are equal: {0}",
                        assemFromType.Equals(currentAssem));
   }
}
// The example displays the following output:
//    Assembly that contains Example:
//       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
//
//    Currently executing assembly:
//       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
//
//    The two Assembly objects are equal: True

Imports System.Reflection

Public Module Example
   Public Sub Main()
      ' Get the assembly from a known type in that assembly.
      Dim t As Type = GetType(Example)
      Dim assemFromType As Assembly = t.Assembly
      Console.WriteLine("Assembly that contains Example:")
      Console.WriteLine("   {0}", assemFromType.FullName)
      Console.WriteLine()
      
      ' Get the currently executing assembly.
      Dim currentAssem As Assembly = Assembly.GetExecutingAssembly()
      Console.WriteLine("Currently executing assembly:")
      Console.WriteLine("   {0}", currentAssem.FullName)
      Console.WriteLine()
      
      Console.WriteLine("The two Assembly objects are equal: {0}",
                        assemFromType.Equals(currentAssem))
   End Sub
End Module
' The example displays the following output:
'    Assembly that contains Example:
'       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
'
'    Currently executing assembly:
'       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
'
'    The two Assembly objects are equal: True

Commenti

Per motivi di prestazioni, è consigliabile chiamare questo metodo solo quando non si conosce in fase di progettazione quale assembly è attualmente in esecuzione. Il modo consigliato per recuperare un Assembly oggetto che rappresenta l'assembly corrente consiste nell'utilizzare la Type.Assembly proprietà di un tipo trovato nell'assembly, come illustrato nell'esempio seguente.

using System;
using System.Reflection;

public class Example
{
   public static void Main()
   {
      Assembly assem = typeof(Example).Assembly;
      Console.WriteLine("Assembly name: {0}", assem.FullName);
   }
}
// The example displays output like the following:
//    Assembly name: Assembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null

Imports System.Reflection

Module Example
   Public Sub Main()
      Dim assem As Assembly = GetType(Example).Assembly
      Console.WriteLine("Assembly name: {0}", assem.FullName)
   End Sub
End Module
' The example displays the following output:
'   Assembly name: Assembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null

Per ottenere l'assembly che contiene il metodo che ha chiamato il codice attualmente in esecuzione, usare GetCallingAssembly.
