Linq approach with FirstOrDefault

string csEndPoint = clientSection.Endpoints.Cast<ChannelEndpointElement>().FirstOrDefault(e => e.Contract == "CsWebService.ICsWebService")?.Address.ToString();

.NET 4.5 and below

string csEndPoint = clientSection.Endpoints.Cast<ChannelEndpointElement>()
                                 .Where(e => e.Contract == "CsWebService.ICsWebService")
                                 .Select(x => x.Address.ToString()).FirstOrDefault();

Try this

string csEndPoint = (from k in clientSettings.Endpoints
         where k.Contract == "CsWebService.ICsWebService"
         select k.Address.ToString()).FirstOrDefault();
