Hey there,

I am using a C# code to define where clause in LINQ. Can someone tell me, how to use this code in asp.net web application?

C#

string inpurUserName = txtName.Text.ToUpper().Trim();
reply= clientService.GetUsers(param,req);

var userTest = reply.Users.Where(x => x.Name == inpurUserName).ToList();

Thanks in advance...

what is clientService.GetUsers?

That is a web service.
Then it returns all the users & then I need to check whether the particular user is available. So that's why i created this linq & it returns 1 if there's values. This is working for C# desktop application. I need this same thing to be done in ASP.NET web app

you can copy past this code in to asp.net page code behind and test
if these methods are re usable for your web projects and desktop projects, then you better create separate class library for common methods.
then you can add reference to that class library from any of your project and call these methods

Infact this "WHERE" clause is not available in asp.net code behind

you need to include System.Linq as using directive at the top of your code behind file in asp.net

C#

using System.Linq;
