Hi. I'm new to C# and WS in general and i'm trying to write a simple windows application that get's the latest article briefs from codeproject's webService, but i keep getting an exception. maybe you can help me out here ? com.codeproject.www.LatestBrief ws = new com.codeproject.www.LatestBrief(); int maxNum = ws.GetMaxArticleListLength(); com.codeproject.www.ArticleBrief[] ar = ws.GetLatestArticleBrief(maxNum); foreach (com.codeproject.www.LatestBrief lb in ar ) { articles.Items.Add(lb.ToString()); } Thanks.

Why don't you tell us what the exception is? It's hard to help you with a problem when we don't know what the problem is. Besides, lb.ToString (defined by LatestBrief.ToString) probably won't give you want you want. By default, ToString returns the type (so "com.codeproject.www.LatestBrief"). You have to output the data yourself, or if articles is an ArrayList or something just add lb, since you can't reconstitute a LatestBrief just from the type name.

Thanks for the reply. The exception information is: An unhandled exception of type 'System.NullReferenceException' occurred in codeProjectWs.exe Additional information: Object reference not set to an instance of an object. When i use the same code to the the messageBoards brief, it works just fine. it seems as if the web service isn't functioning properly. as for the .ToString, i get you. Thanks again.
