[mono-cecil] Re: Type Dependencies Revisited

[Lev Danielyan]

Here is the source code for the method:

static class IListExtension
    {
        public static void AddNotExist<T>(this IList<T> list, T type)
        {
            if (!list.Contains(type))
            {
                list.Add(type);
            }
        }
    }

    static class TypeExtensions
    {
        public static IEnumerable<MethodDefinition> GetMethods(this
TypeDefinition type)
        {
            foreach (MethodDefinition method in type.Methods)
            {
                yield return method;
            }

            foreach (MethodDefinition method in type.Constructors)
            {
                yield return method;
            }
        }
    }

    class Dependencies
    {
        public static IList<TypeReference> GetDependencies
(TypeDefinition type)
        {
            var dep = new List<TypeReference>();

            dep.AddNotExist(type.BaseType);

            foreach (CustomAttribute attr in type.CustomAttributes)
            {
                TypeReference tref = attr.Constructor.DeclaringType;

                dep.AddNotExist(tref);
            }

            foreach (FieldDefinition field in type.Fields)
            {
                dep.AddNotExist(field.FieldType);
            }

            foreach (MethodDefinition method in type.GetMethods())
            {
                if (!method.HasBody) continue;

                foreach (Instruction instruction in
method.Body.Instructions)
                {
                    var methodOp = instruction.Operand as
MemberReference;
                    if (methodOp != null)
                        dep.AddNotExist(methodOp.DeclaringType);
                }

                dep.AddNotExist(method.ReturnType.ReturnType);

                foreach (ParameterDefinition parameter in
method.Parameters)
                {
                    dep.AddNotExist(parameter.ParameterType);
                }
            }

            return dep;
        }
    }
