Hi All,
I have a factory which has some concrete sub classes for generating reports (.txt, .csv,.xls) I want to make the interface of the concrete classes to be generic so that i can pass in diff types of parameters (Instead of DataTable i need to use DataSet or some other class instance as argument). Here is my previous interface.

  interface IReportCreator
        bool Create(DataTable dt);

I made the interface as generic..like the one below

interface IReportCreator<T>
    bool Create(T args);

Now my question is how can i return the generic interface from the Factory My previous factory code
My previous factory code is like the one below..

class Factory
    static IReportCreator  GetReportCreator(string type)
        IReportCreator reportCreator = null;
        if(type == "txt")
            reportCreator = new TextCreator(); 

        if(type == "csv")
            reportCreator = new CSVCreator();

        return reportCreator;

And in the cient.. i call like this

IReportCreator repCreator = Factory.GetReportCreator("txt"); 
repCreator.Create(// the argument);

I want to make the factory as a generic one.. Pls help me to solve this

Any help will be appreciated greatly

Not sure what you are asking, but to make a generic, you need a generic type indicator

class Factory<T> {
