How to pass a Generic class as a Parameter to a non-generic class constructor [duplicate]

Question

Assume the following code (Please read my question in the code comments in the final class):

//This is my Generic Class
public class ClientRequestInfo<K, V>
{
    public string Id { get; set; }
    private Dictionary<K, V> parameters;

    public ClientRequestInfo()
    {
        parameters = new Dictionary<K, V>();
    }

    public void Add(K key, V value)
    {
        parameters.Add(key, value);
    }
 }

public class ProcessParameters()
{
    private void CreateRequestAlpha()
    {
        ClientRequestInfo<int, string> info = new ClientRequestInfo<int, string>();
        info.Add(1, "Hello");
        SynchRequest s = new SynchRequest(info);
        s.Execute();
    }
    private void CreateRequestBeta()
    {
        ClientRequestInfo<int, bool> info = new ClientRequestInfo<int, bool>();
        info.Add(1, true);
        SynchRequest s = new SynchRequest(info);
        s.Execute();
    }
}

public class SynchRequest
{
    //What type should I put here?
    //I could declare the class as SynchRequest<K, V> but I don't want
    //To make this class generic.
    private ClientRequestInfo<????,?????> info;
    private SynchRequest(ClientRequestInfo<?????,?????> requestInfo)
    {
        //Is this possible?
        this.info = requestInfo;
    }

    public void Execute()
    {}
}

If you don't want to make SynchRequestInfo generic, can you make a non-generic base class for ClientRequestInfo? --

public abstract class ClientRequestInfo
{
    public abstract void NonGenericMethod();
}

public class ClientRequestInfo<K, V> : ClientRequestInfo
{
    public override void NonGenericMethod()
    {
        // generic-specific implementation
    }
}

Then:

public class SynchRequest
{
    private ClientRequestInfo info;

    private SynchRequest(ClientRequestInfo requestInfo)
    {
        this.info = requestInfo;
    }

    public void Execute()
    {
        // ADDED: for example
        info.NonGenericMethod();
    }
}
