The name 'HttpContext' does not exist in the current context

Question

I am trying to convert some vb.net to C#, but I keep getting errors. At the moment, I am getting the error in the title.

The problem line is:

string[] strUserInitials = HttpContext.Current.Request.ServerVariables("LOGON_USER").Split(Convert.ToChar("\\"));

Anyone know why this is happening?

I am working on a webservice (asmx file).

I have the following at the top of the code:

using System.Web;
using System.Web.Services;
using System.Web.Script.Services;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;

Answer 1

You have to reference to System.Web and import the namespace System.Web:

using System.Web;

I would not use Convert at all:

string[] strUserInitials = System.Web.HttpContext.Current.Request.ServerVariables["LOGON_USER"].Split('\\'));

Answer 2

You need [] instead of ():

string[] strUserInitials = System.Web.HttpContext.Current.Request.ServerVariables["LOGON_USER"].Split(System.Convert.ToChar(@"\"));

Answer 3

put using System.Web; and using System; into the source file...
