One i can think is a tree or a graph, where each node is defined as the collection of all its children.

yeah, i thought of the same with nodes... but the thing is, on an engineering standpoint we already have better implimentations of a node... wont a collection as a node just bloat everything? Sigh | :sigh:

newez, was just hoping for something 'unique' that it can solve with... or maybe im just crossing the line where it says 'bad design on generics' here... Frown | :(

what im really fussing about is that this can be more than just on collections... its generic interfaces, objects, and what nots on itself... u know... WTF | :WTF:

How about a factory

public class GenericFactory<T> where T : new()
{
  public T Create(){
     return new T();
  }
}

no, the guy up there got it... i wanted to see the declared type (itself) being passed back into the generic... (with some sense into it)

i tried

DateTime createdDate;
             createdDate = Convert.ToDateTime(result.GetString(1));

but didn't work.

What's the value in result.GetString(1)? Try pausing at this line and then see what the data is that's in there.

It sounds to me like there's a culture problem here. In other words, the format on the system doesn't match the format of data in the database.

System.InvalidCastException: Unable to cast object of type 'System.DateTime' to type 'System.String'.

this one is showing as error.
i declare the variable as datetime and string as well but it gave the same error in both. it seems since my datafield is datetime, it is having problem when i am extracting that datetime.

Assuming that result is a data reader or an sql parameter:

DateTime dateTime = (DateTime)dataReader["columnName"]

DateTime dateTime = (DateTime)sqlParameter.Value;

Are the most correct answers. If the field allows null, check for DbNull.Value first.

Do not use strings for date/times if you can avoid it, as it opens up a whole range of potential problems. Instead have a datetime field in the database, and a DateTime variable in your code; then do what Ennis said.

If you must use strings, make sure to use a universal format. More is here[^]

I dont think anyone of you understood my problem. Let me explain again.

I have a table as

CREATE TABLE [dbo].[tblTest](
	[ID] [int] IDENTITY(1,1) NOT NULL,

	[Date] [datetime] NULL	)

Now I am retrieving that value :

DateTime createdDate;
          SqlCommand command = new SqlCommand("SELECT ID,Date FROM tblTest WHERE ID = '1'", myConnection);


          SqlDataReader result = command.ExecuteReader();
          if (result.Read())
          {
              //set the editor text

              createdDate = result.GetString(1);
          }

when i did this , it gave error.

System.InvalidCastException: Unable to cast object of type 'System.DateTime' to type 'System.String'.

so i declared createdDate as string and tried again. It gave the same error. So I thought its the problem when we are retrieving datetime field from the database. I tried this query in query analyzer, and it is working fine.

I even tried this:

createdDate =(DateTime)(result.GetString(1));

but same error.

Damn - I really should read these things through first. Basically, you are trying to read a datetime out as a string here. The code should read

if (!result.IsDBNull(1))
  createdDate = result.GetDateTime(1);
