c# - Implementing generic interface that takes a generic interface as a parameter -

i have these 2 interfaces

    /// <summary> ///     represents interface knows how 1 type can transformed type. /// </summary> /// <typeparam name="tinput"></typeparam> /// <typeparam name="toutput"></typeparam> public interface itransformer<in tinput,out toutput> {     toutput transform(tinput input); }  public interface itransform {     toutput transform<tinput,toutput>(itransformer<tinput, toutput> transformer); } 

i have class in in want implement itranform this.

public class messagelogs :itransform {     // am not able implement itransform interface    // messagelogs getting binded in param not getting binded   // tinput in transform<tin,tout>      //      public t transform<messagelogs, t>(itransformer<messagelogs, t> transformer)     {         return transformer.transform(this);     }   } 

how correctly without losing genericness of 2 interfaces? have many tranformers.

the interface requires implemented method generic in both tinput , toutput. in other words, messagelogs must able accept other types tinput well. that's not want. you're going need like:

public interface itransformer<in tinput,out toutput> {     toutput transform(tinput input); }  public interface itransform<tinput> {     toutput transform<toutput>(itransformer<tinput, toutput> transformer); }  public class messagelogs : itransform<messagelogs> {     public toutput transform<toutput>(itransformer<messagelogs, toutput> transformer)     {         return transformer.transform(this);     } }
