Hi,
I want to search the array of user-defined object, say user-defined class is as below.
CODE

public class ServiceTypes
     {
     public int ServiceID;
     public string ServiceName;
     public int VendorID;
     }


On the windows form, I have one combo box control thru which I can get VendorID.

Now, I want to search thru the ServiceTypes - array based on the value of VendorID selected in the combo.

Note: I can not use Array.FindAll, as I need to search ServiceTypes based on the value selected in VendorID combo.

Can anyone help to find good performance solution? - I know about search thru the array and prepare new based on the VendorID.

Thanx
Yagnesh

You can use FindAll, you just have to know how to ask the question. wink2.gif

Here's the code:
csharp

ServiceTypes[] FindAllTest(ServiceTypes[] list, int vendorId) {
   return Array.FindAll(list,
      delegate(ServiceTypes item) { return item.VendorID == vendorId; }
   );
}


Also, look into List<ServiceTypes>, it's generally a better solution to an array. Delegates are exceptionally useful tools. If you start to use Generics, then even more so.

Hope this helps.
