I've got two classes that I would like to merge/map by the Name property in each of them

public class Parameter
{
   public string Name { get; set; }
   public string Value { get; set; }
}

public class RuleSetParameter
{
    public string ParameterName { get; set; }
    public string ParameterValue { get; set; }
    public int ParameterType { get; set; }
 }

I would like to merge these two lists, by joining them on the Name <-> ParameterName props, so that I can get the ParameterValue.

This is what I have thus far:

var parameterDictionary = RuleSetParameter.Zip(parameters).ToDictionary(x => x.First, x => x.Second);

I know this won't work, because this will just map them in the order received.

Any guidance on how to achieve the desired result?

Managed to get this resolved using the Join method:

 var result = fieldMap.RuleSetParameter.Join(parameters, arg => arg.ParameterName, arg => arg.Name,
                (first, second) => new { first.ParameterName, ParameterValue = second.Value, first.ParameterType });

I would define an interface

public interface IParameter
{
   string Name { get; set; }
   string Value { get; set; }
}

public class Parameter : IParameter
{
   public string Name { get; set; }
   public string Value { get; set; }
}

public class RuleSetParameter : IParameter
{
    public string ParameterName { get; set; }
    public string ParameterValue { get; set; }
    public int ParameterType { get; set; }

    //explicit interface implementation 
    string IParameter.Name 
    { 
        get => this.ParameterName;
        set => this.ParameterName = value;
    }
    string IParameter.Value
    { 
        get => this.ParameterValue;
        set => this.ParameterValue = value;
    }
}

Now you can easily define a IDictionary<string, IParameter>

var parameters = new List<Parameter>()
{
    new() { Name = "P1", Value = "V1" },
    new() { Name = "P2", Value = "V2" },
};

var resultSetParameters = new List<RuleSetParameter>()
{
    new() { ParameterName = "RP1", ParameterValue = "RV1" },
    new() { ParameterName = "RP2", ParameterValue = "RV2" },
};

var dictParametrs = parameters.Cast<IParameter>().Concat(resultSetParameters).ToDictionary(x => x.Name);
