问如何在mono cecil中引用GenericInstanceType上的GenericInstanceMethod

EN

class Foo<T1> {
    void Bar<T2>(int value) {...}
}

static public GenericInstanceMethod MakeGenericMethod(this MethodReference method, TypeReference[] genericArguments)
{
    var _method = new GenericInstanceMethod(method);
    foreach (var _argument in genericArguments) {
        _method.GenericArguments.Add(genericArguments);
    }
    return _method;
}

Foo<>.Bar<T2>(int)

static public MethodReference Reference(this GenericInstanceType genericInstanceType, MethodReference method)
    _methodReference = new MethodReference(method.Name, _returnType, genericInstanceType) {
        HasThis = method.HasThis,
        ExplicitThis = method.ExplicitThis,
        CallingConvention = method.CallingConvention
    };
    foreach (var parameter in method.Parameters) {
        _methodReference.Parameters.Add(parameter);
    }
    return _methodReference;  
}

Foo<T1>.Bar(int);
