c# - Implement interface and use code from existing implementation of the interface -

i'm trying implement itableentity interface can add [datacontract] attribute on it. if implement interface myself, i'll have give readentity , writeentity methods body.

but there class implements itableentity interface , gave readentity , writeentity methods body, tableentity.cs.

how can make implementation of interface use methods in tableentity class?

[edit]

[datacontract] public class serializabletableentity : itableentity  {     private tableentity tableentity;      public string etag { get; set; }     public string partitionkey { get; set; }     public string rowkey { get; set; }     public datetimeoffset timestamp { get; set; }      public serializabletableentity()     {         tableentity = new tableentity();     }      public void readentity(idictionary<string, entityproperty> properties, microsoft.windowsazure.storage.operationcontext operationcontext)     {         tableentity.readentity(properties, operationcontext);     }      public idictionary<string, entityproperty> writeentity(microsoft.windowsazure.storage.operationcontext operationcontext)     {         return tableentity.writeentity(operationcontext);     } } 

the reason every property in stored table blank because writeentity , readentity use blank object store , write data.

you're delegating serialization of object 'tableentity' none of properties there.

suggestion: need implement of serializabletableentity's properties inside class derives tableentity, contain variable of type inside serializabletableentity entity, , delegate every member's property get/set serializabletableentity new object.

does make sense?

edit: code sample requested (you're not going enjoy though)

    [datacontract] public class serializabletableentity : itableentity {     private customentity tableentity;      public string etag {      {                 {             return tableentity.etag;         }         set         {             tableentity.etag = value;         }     }      public string partitionkey     {                 {             return tableentity.partitionkey;         }         set         {             tableentity.partitionkey = value;         }     }      public string rowkey     {                 {             return tableentity.rowkey;         }         set         {             tableentity.rowkey = value;         }     }      public datetimeoffset timestamp     {                 {             return tableentity.timestamp;         }         set         {             tableentity.timestamp = value;         }     }      public string propertyone     {                 {             return tableentity.propertyone;         }         set         {             tableentity.propertyone = value;         }     }       public serializabletableentity()     {         tableentity = new customentity();     }      public void readentity(idictionary<string, entityproperty> properties, microsoft.windowsazure.storage.operationcontext operationcontext)     {         tableentity.readentity(properties, operationcontext);     }      public idictionary<string, entityproperty> writeentity(microsoft.windowsazure.storage.operationcontext operationcontext)     {         return tableentity.writeentity(operationcontext);     } }  public class customentity : tableentity {     public string propertyone { get; set; } }
