c# – Reflection.emit System.InvalidProgramException：公共语

public class RepositoryWrapper
{
    public void CallRepositoryMethod(IAddressRepository repository,Address address)
    {
        repository.NODE_I_NodeExtendedDetails_Address3(address.NodeId);
    }
}

这是它的代表：

IL_0000: nop
    IL_0001: ldarg.1
    IL_0002: ldarg.2
    IL_0003: callvirt instance int32 ReflectionServices.Node::get_NodeId()
    IL_0008: callvirt instance void ReflectionServices.IAddressRepository::NODE_I_NodeExtendedDetails_Address3(int32)
    IL_000d: nop
    IL_000e: ret

这是我用来创建它的代码：

internal static void Generate(this System.Reflection.Emit.ILGenerator @this,Type target,string method,Type instance)
        {

        var methodToCall = target.GetMethod(method);
        var methodParams = methodToCall.GetParameters();
        var instanceProperties = instance.GetProperties(BindingFlags.Public | BindingFlags.Instance);

        var orderedProperties = (from mp in methodParams
                              join p in instanceProperties
                              on mp.Name.ToLower() equals p.Name.ToLower()
                              select p).ToArray();

        //add properties to the string builder

        //load the object reference onto the stack sothat we can access its methods
        @this.Emit(OpCodes.Nop);
        @this.Emit(OpCodes.Ldarg_1);
        @this.Emit(OpCodes.Ldarg_2);

            var property = orderedProperties.FirstOrDefault(x => x.Name == "NodeId");
            if (property != null)
            {
                var getMethod = property.GetGetMethod();
                @this.Emit(getMethod.IsVirtual ? OpCodes.Callvirt : OpCodes.Call,getMethod);

            }


        //call method 
            @this.Emit(methodToCall.IsVirtual ? OpCodes.Callvirt : OpCodes.Call,methodToCall);
            @this.Emit(OpCodes.Nop);
        //return from function
        @this.Emit(OpCodes.Ret);
        }

这是我得到的错误：

System.InvalidProgramException: Common Language Runtime detected an invalid program.
Result StackTrace:  
at ReflectionServices.Repository.NODE_I_NodeExtendedDetails3_Address40807399(Repository      target,Address )

这是生成的il：

nop
ldarg.1
ldarg.2
call instance int32 ReflectionServices.Node::get_NodeId()
callvirt instance void            
ReflectionServices.Repository::
                               NODE_I_NodeExtendedDetails3_Address(int32)
nop

RET

任何人都可以看到我遇到的问题是什么？

谢谢

这是我要求的dll和方法：

public sealed class ReflectionEmitWithDebuggingMethodGenerator
{
    private AssemblyBuilder Assembly { get; set; }
    private ModuleBuilder Module { get; set; }
    private AssemblyName Name { get; set; }

    public ReflectionEmitWithDebuggingMethodGenerator()
        : base()
    {
        this.Name = new AssemblyName() { Name = Guid.NewGuid().ToString("N") };
        this.Assembly = AppDomain.CurrentDomain.DefineDynamicAssembly(
            this.Name,AssemblyBuilderAccess.RunAndSave,@"C:UsersdarrenDocumentsVisual Studio 2012ProjectsUnityInjection");
        this.AddDebuggingAttribute(this.Assembly);
        this.Module = this.Assembly.DefineDynamicModule(this.Name.Name + ".dll",true);
    }
   public Action<TObject,TInstance> Generate<TObject,TInstance>(Type target,string methodN,Type instanceType)
    {
        var type = this.Module.DefineType(target.Namespace + "." + target.Name);
        var methodName = methodN + target.GetHashCode().ToString();
        var method = type.DefineMethod(methodName,MethodAttributes.Static | MethodAttributes.Public,typeof(void),new Type[] { target,instanceType });
        method.DefineParameter(1,ParameterAttributes.In,"target");
        method.DefineParameter(2,"instance");

        ILGenerator.Generate(method.GetILGenerator(),target,methodN,instanceType);

        var createdType = type.CreateType();

        var createdMethod = createdType.GetMethod(methodName);
        return (Action<TObject,TInstance>)Delegate.CreateDelegate(typeof(Action<TObject,TInstance>),createdMethod);
    }
