System.Net.WebClient

Added in .NET Framework 1.1
This is derived from the System.Net.WebRequest class.
This class is a higher-level abstraction built on top of HttpWebRequest to simplify the most common tasks



Create

string templateName = "templateName"; 
string returnText = "";

string restURL = "https:\\bettersolutions.com\

var request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(restURL);
request.AutomaticDecompression = System.Net.DecompressionMethods.GZip;
request.Method = "GET";
request.ContentType = "application/json";
request.CookieContainer = new System.Net.CookieContainer();
request.AllowAutoRedirect = true;
request.UseDefaultCredentials = true;
request.Timeout = (int)TimeSpan.FromMinutes(1).TotalMilliseconds;

using (var reader = new System.IO.StreamReader(request.GetResponse().GetResponseStream(), System.Text.Encoding.UTF8, true))
{
     System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();
     var objText = reader.ReadToEnd();
     returnValue = js.Deserialize(objText, typeof(ModelCoverProject.DiscTextJsonResponse));
}


OpenRead

Dim objStream As System.IO.Stream 
Dim objStreamReader As System.IO.StreamReader
Dim oWebClient As System.Net.WebClient

objWebClient = New System.Net.WebClient
objWebClient.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials
objWebClient.Credentials = New System.Net.NetworkCredential(username, password, domain)

objStream - objWebClient.OpenRead(sURL)
objStreamReader = New System.IO.StreamReader(objStream)

This method copies the existing Headers, Credentials, and method to the newly created WebRequest object.

public static void Main (string[] args) 
{
     System.Net.WebClient oWebClient = new System.Net.WebClient();
     oWebClient.Headers.Add ("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
     Stream data = oWebClient.OpenRead (args[0]);

     StreamReader reader = new StreamReader (data);
    string s = reader.ReadToEnd ();
    Console.WriteLine (s);
    data.Close ();
    reader.Close ();
}


DownloadString

public static string HttpGet(string uri) 
{
    string content = null;
    System.Net.WebClient oWebClient;
 
    oWebClient = new System.Net.WebClient();
    content = oWebClient.DownloadString(uri);
 
    return content;
}
