FindFirst method of VB6 in VB.Net?

Is there any possibility of using something like FindFirst, FindNext, FindLast methods, that we use in VB6? I need to search my database before adding record, if record under current name is already there or not. Say I have a telephone book, I donot want any n开发者_开发问答ame to go again without warning. Thanks Furqan

If you allowed to use LINQ, you may use the method Any(predicate).

Are you using ADO.NET? The Recordset Object has a Find method:
