Hello,

please look at the following method:

public static bool BindReport<t>(CrystalReportViewer viewer, DataTable dt, List<string> paramNames, List<string> paramValues) where T : class, new()
       {
           try
           {
               SetParameters(paramNames, paramValues, viewer);
               T rpt = new T();
               rpt.SetDataSource(dt);   /*actually no "SetDataSource" method found; but i need that*/
               viewer.ReportSource = rpt;
           }
           catch (exception ex)
           {
               throw ex;
           }
           return true;
       }

I need to do something with

C#

where T : class, new()

Please suggest me.

What do you mean with "I need to do something with"?

This

C#

where T : class, new()

means that the T type must be a class and have a constructor. Have a look at Constraints on Type Parameters (C# Programming Guide)[^] for a more detailed description.

I mean that, If I can declare a base class for all of my crystal Reports then, I can declare it as where T : myBasicReportClass, new() and thus I can get the SetDataSource Method.
