Exemplos

O exemplo a seguir obtém o assembly de chamada do método atual.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
// Assembly FirstAssembly
using System;
using System.Reflection;
using System.Runtime.CompilerServices;
namespace FirstAssembly
{
    public class InFirstAssembly
    {
        public static void Main()
        {
            FistMethod();
            SecondAssembly.InSecondAssembly.OtherMethod();
        }

        [MethodImpl(MethodImplOptions.NoInlining)]
        public static void FirstMethod()
        {
            Console.WriteLine("FirstMethod called from: " + Assembly.GetCallingAssembly().FullName);
        }
    }
}

// Assembly SecondAssembly
using System;

using System.Runtime.CompilerServices;

namespace SecondAssembly
{
    class InSecondAssembly
    {
        [MethodImpl(MethodImplOptions.NoInlining)]
        public static void OtherMethod()
        {
            Console.WriteLine("OtherMehod executing assembly: " + Assembly.GetExecutingAssembly().FullName);
            Console.WriteLine("OtherMethod called from: " + Assembly.GetCallingAssembly().FullName);
        }
    }
}
// The example produces output like the following:
// "FirstMethod called from: FirstAssembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"
// "OtherMethod executing assembly: SecondAssembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"
// "OtherMethod called from: FirstAssembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"

Module Example
   Public Sub Main()
      ' Instantiate a target object.
      Dim int1 As Integer
      ' Set the Type instance to the target class type.
      Dim type1 As Type =int1.GetType()
      ' Instantiate an Assembly class to the assembly housing the Integer type.
      Dim sampleAssembly = Assembly.GetAssembly(int1.GetType())
      ' Display the name of the assembly that is calling the method.
      Console.WriteLine(("GetCallingAssembly = " + Assembly.GetCallingAssembly().FullName))
   End Sub
End Module
' The example displays output like the following:
'   GetCallingAssembly = Example, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null

Comentários

Se o método que chama o GetCallingAssembly método for expandido embutido pelo compilador JIT (just-in-time) ou se seu chamador for expandido em linha, o assembly retornado por GetCallingAssembly pode diferir inesperadamente.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. Por exemplo, considere os seguintes métodos e assemblies:For example, consider the following methods and assemblies:

  • Método M1 em chamadas A1 deassembly.GetCallingAssemblyMethod M1 in assembly A1 calls GetCallingAssembly.

  • Método M2 em chamadas A2 deassembly.M1Method M2 in assembly A2 calls M1.

  • Método M3 em chamadas A3 deassembly.M2Method M3 in assembly A3 calls M2.

Quando M1 não é embutido, GetCallingAssembly retorna A2.When M1 is not inlined, GetCallingAssembly returns A2. Quando M1 é embutido, GetCallingAssembly retorna A3.When M1 is inlined, GetCallingAssembly returns A3. Da mesma forma M2 , quando não é embutido GetCallingAssembly , A2retorna.Similarly, when M2 is not inlined, GetCallingAssembly returns A2. Quando M2 é embutido, GetCallingAssembly retorna A3.When M2 is inlined, GetCallingAssembly returns A3.

Esse efeito também ocorre quando M1 o é executado como uma chamada tail M2de, ou M2 quando é executado como uma chamada tail M3de.This effect also occurs when M1 executes as a tail call from M2, or when M2 executes as a tail call from M3. Você pode impedir que o compilador JIT indique o método que chama GetCallingAssembly, aplicando o MethodImplAttribute atributo com o MethodImplOptions.NoInlining sinalizador, mas não há nenhum mecanismo semelhante para evitar chamadas 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.
