I'm trying to encode a URL using the HttpUtility.UrlEncode()
method, why am I getting
The type or namespace name 'HttpUtility' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)
error ? I'm using Visual C# 2008, Express Edition.
The code I'm using is simplistic:
using System; using System.Text; using System.Windows.Forms; using System.Net; using System.IO; using System.Web; namespace Lincr { public partial class frmMain : Form { public frmMain() { InitializeComponent(); } private void cmdShorten_Click(object sender, EventArgs e) { WebRequest wrURL; Stream objStream; wrURL = WebRequest.Create("http://lin.cr?l=" + System.Web.HttpUtility.UrlEncode(txtURL.Text) + "&mode=api&full=1"); objStream = wrURL.GetResponse().GetResponseStream(); StreamReader objSReader = new StreamReader(objStream); textBox1.Text = objSReader.ReadToEnd().ToString(); } } }
You need to include a reference to System.Web
. Right-click your project in the Solution Explorer and choose Add Reference... . If you take a look at MSDN you'll see it's contained in the System.Web.dll
assembly, as far as I remember, this is not referenced by default in new projects.
