it fixes the issue unbox pushes a managed pointer to the value onto the evaluation stack, not the value itself. Try using unbox.any instead. – Lee

MSIL - how do you invoke a private method from MSIL?

MSIL - how do you invoke a private method from MSIL?

Hope this helps The solution (to my particular problem), was to used delegates instead of direct method calls. You can comfortably construct an open delegate and pass it to the IL code, and then when the IL code invokes the delegate's Invoke method, the JIT accepts the pattern as legal and allows the invoke of the private methods.
Like I said, this is a solution (which happily allows runtime-generated code to call private methods), though it still doesn't explain how technolgies like Expression Trees and Reflection manage to call private methods.

To fix this issue When a var-arg method is invoked, the parameters get converted into an array of that type at compile time.
In the first call, the parameters get converted to an int[]. As all arrays in Java are direct sub types of the Object class, the concept of primitive widening does not apply in which case, both the overloads become equally applicable because long[] and Integer[] are at the same level. Hence the ambiguity

I wish this helpful for you I tried to make a generic helper method using Moq with nunit as described below , Problem was a missing Exception in the Where clause. Should be
code :
public void PrepareWebRequest<T>() where T : Exception, new()
{            
    httpCommunicator = new Mock<IHttpCommunicator>();
    httpCommunicator.Setup(x => x.Post(It.IsAny<Object>(),
                                                  It.IsAny<string>())).Throws<T>();

    service = new ApiClient(httpCommunicator.Object);
}

wish help you to fix your issue I'm quite certain that the JIT is able to compile code that uses Reflection. If not, you wouldn't be able to use Reflection.Emit, ever. The MSIL you generate goes through the same JIT process as MSIL generated by the C# compiler.
There is a bit of a difference when it comes to CAS checks, but I see nothing to suggest that you're operating in a partial trust scenario to begin with.
code :
generator.Emit(OpCodes.Newobj,
typeof(DynamicMethod).GetConstructor(
    new Type[] { typeof(string), typeof(Type), typeof(Type[]) }));
DynamicMethod method = new DynamicMethod(typeof(int).ToString()+".op_Addition",
                                         typeof(int),
                                         new Type[] { typeof(int), typeof(int) }, 
                                         typeof(Program));

fixed the issue. Will look into that further That message is a little odd. I'm not sure exactly why you're getting it. But one thing you should change is this:
