Re: About generics - C# Discussion Boards

ok, now i can see that this is possible;

class Animals: IEnumerable<Animals> {};

forget about the IEnumerable, im just trying to show some generic type of itself... im just bothered... where can we make use of this (a generic type of itself) in the real world?

Yep, even our animals are smart enough to enumerate themselves.

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

E. del Ayre25-Oct-10 23:19

25-Oct-10 23:19

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 | :(

E. del Ayre25-Oct-10 23:25

25-Oct-10 23:25

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();
  }
}

Link a custom PerformanceCounter to the XP Performance Monitor

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)

[FILE DATA]

This is a header send by client on file upload. But the problem is that I do not want to use default HttpRequest instance. All I need to get file name and file data. What is best way to parse this. The line index ? Regex ?

I have just created a PerformanceCounterCategory which includes various counters type (CounterCreationData), and later using the PerformanceCounter I access to one of this counters in order to operate with them (Increment, IncrementBy ...) but my problem is how to connect my counter to the Monitor (perfmon.exe) included in XP Operative System, I don´t find in it my Category nor counters.

Best Regards

I have datetime field in the table in my database. How to assign that datetime in my local variable ?

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.
