Nell'esempio seguente viene ottenuto l'assembly chiamante del metodo corrente.The following example gets the calling assembly of the current method.

using namespace System;
using namespace System::Reflection;

void main()
{
   // Instantiate a target object.
   Int32 integer1 = 0;
   // Set the Type instance to the target class type.
   Type^ type1 = integer1.GetType();
   // Instantiate an Assembly class to the assembly housing the Integer type.
   Assembly^ sampleAssembly = Assembly::GetAssembly(integer1.GetType());
   // Display the name of the assembly that is calling the method.
   Console::WriteLine("GetCallingAssembly = {0}", Assembly::GetCallingAssembly()->FullName);
}
// The example displays output like the following:
//    GetCallingAssembly = Example, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null

Commenti

Se il metodo che chiama il metodo GetCallingAssembly viene espanso in linea dal compilatore just-in-time (JIT) o se il chiamante è espanso inline, l'assembly restituito da GetCallingAssembly può differire in modo imprevisto.If the method that calls the GetCallingAssembly method is expanded inline by the just-in-time (JIT) compiler, or if its caller is expanded inline, the assembly that is returned by GetCallingAssembly may differ unexpectedly. Si considerino, ad esempio, i metodi e gli assembly seguenti:For example, consider the following methods and assemblies:

  • Il metodo M1 nell'assembly A1 chiama GetCallingAssembly.Method M1 in assembly A1 calls GetCallingAssembly.

  • Il metodo M2 nell'assembly A2 chiama M1.Method M2 in assembly A2 calls M1.

  • Il metodo M3 nell'assembly A3 chiama M2.Method M3 in assembly A3 calls M2.

Quando M1 non è inline, GetCallingAssembly restituisce A2.When M1 is not inlined, GetCallingAssembly returns A2. Quando M1 viene reso inline, GetCallingAssembly restituisce A3.When M1 is inlined, GetCallingAssembly returns A3. Analogamente, quando M2 non è inline, GetCallingAssembly restituisce A2.Similarly, when M2 is not inlined, GetCallingAssembly returns A2. Quando M2 viene reso inline, GetCallingAssembly restituisce A3.When M2 is inlined, GetCallingAssembly returns A3.

Questo effetto si verifica anche quando M1 viene eseguito come chiamata tail da M2o quando M2 viene eseguito come chiamata tail da M3.This effect also occurs when M1 executes as a tail call from M2, or when M2 executes as a tail call from M3. È possibile impedire al compilatore JIT di incorporare il metodo che chiama GetCallingAssembly, applicando l'attributo MethodImplAttribute con il flag MethodImplOptions.NoInlining, ma non esiste un meccanismo simile per impedire le chiamate tail.You can prevent the JIT compiler from inlining the method that calls GetCallingAssembly, by applying the MethodImplAttribute attribute with the MethodImplOptions.NoInlining flag, but there is no similar mechanism for preventing tail calls.
