Pass type as string variable

I was thinking something like

public class ValueProcessor : IValueProcessor
{
        public ClusterResource ClusterResource(string data)
    {
       //return something here
}
///////////////////.................

and

public interface IValueProcessor
{
   string ClusterResource(string data);
///////////////.....
}

And

private readonly IValueProcessor _valueProcessor;
public SwitchDemo(IValueProcessor valueProcessor)
{
    _valueProcessor = valueProcessor;
}

again this is untested
