Conversion of C# system type in a custom type

Question

Its C# class library project. Class has only one function which returns a dictionary,

//dictionary definition 
Dictionary<string, int> stockLengths = new Dictionary<string, int>();
    stockLengths.Add("Length_5000", 0);
    stockLengths.Add("Length_3000", 0);

//return statement
Value result = new Value(stockLengths);
    return result;

the system calling class library is not accepting the dictionary with following error:

" Use Configurator Types instead of System.Type System.Collections.Generic.Dictionary`2[System.String,System.Int32] "

Here Configurator = A custom software, which is calling the class library dll...

What am i missing here, can convert a system type of dictionary into any custom type so that the host system can accept data type being returned...

// Value struct

 public struct Value : IEquatable<Value>
    {
        public static readonly Value Null;

        public Value(string value);
        public Value(decimal? value);
        public Value(decimal value);
        public Value(bool? value);
        public Value(bool value);
        public Value(IExpressionValue value);
        public Value(IExpressionValueCollection value);
        public Value(IExpressionValueArray value);
        public Value(DataType valueType);
        public Value(object value);

        public object Data { get; }
        public bool HasValue { get; }
        public Type ValueType { get; }
        public DataType Type { get; }

        public static implicit operator Value(decimal? value);

        public static implicit operator Value(bool? value);
        public static implicit operator Value(decimal value);
        public static implicit operator Value(string value);
    }

Answer 1

The solution was not available in provided docs, when I contacted technical support they only offered a tip and then with a little bit more exploring I was able to successfully convert the system data type into "THE" data type which host software support... Here I am providing solution, to help out someone like me:

    using TDCI.BuyDesign.Configurator.Engine;
    using TDCI.BuyDesign.Configurator.Engine.Expressions;
    using TDCI.BuyDesign.Configurator.Engine.RuleEngine;

            // sample code to return Collections 
            var returnCollection = new SimpleExpressionValueCollection();
            returnCollection.Add("Length_5000", 5000);
            returnCollection.Add("Length_3000", 3000);

            Value result = new Value(returnCollection);
            return result;
            
            // sample code to return arrays 
            var returnArrays = new SimpleExpressionValueArray(DataType.String);
            returnArrays.Add(new SimpleExpressionValue("Test Value 1"));
            returnArrays.Add(new SimpleExpressionValue("Test Value 2"));
            returnArrays.Add(new SimpleExpressionValue("Test Value 3"));

            Value result = new Value(returnArrays);
            return result;
