string f = TranslateText("hi", "English", "German", "", "");
MessageBox.Show(f);
}

public string TranslateText(string inputText, string sourceLanguage, string destinationLanguage, string referrer, string apiKey)
{
string requestUrl = string.Format(

try

HttpWebRequest http = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
http.Referer = referrer;
HttpWebResponse response = (HttpWebResponse)http.GetResponse();

var translation = this._Serializer.Deserialize<Milkshake.Integration.Google.GoogleAjaxResponse<Milkshake.Integration.Google.Translate.TranslationResponse>>(responseJson);

I've used HttpClient in .NET 4.0 applications on numerous occasions. If you are familiar with NuGet, you can do an Install-Package Microsoft.Net.Http to add it to your project. See the link below for further details.
http://nuget.org/packages/Microsoft.Net.Http
You can use WebClient.
Or (if you need more fine-grained control over the request) HttpWebRequest
Or, HttpClient in System.Net.Http.dll.
Here's a "translation" to HttpWebRequest (needed rather than WebClient in order to set the referrer). (Uses System.Net and System.IO):
HttpWebRequest http = (HttpWebRequest)HttpWebRequest.Create(requestUrl))
http.Referer = referrer;
HttpWebResponse response = (HttpWebResponse )http.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
string responseJson = sr.ReadToEnd();
// more stuff
}
Referring to the answers above, I am only adding this to help clarify things. It is possible to use HttpClient from .Net 4.0, and you have to install the package from here
However, the text is very confusion and contradicts itself.
This package is not supported in Visual Studio 2010, and is only required for projects targeting .NET Framework 4.5, Windows 8, or Windows Phone 8.1 when consuming a library that uses this package.
But underneath it states that these are the supported platforms.
Supported Platforms:
.NET Framework 4
Windows 8
Windows Phone 8.1
Windows Phone Silverlight 7.5
Silverlight 4
Portable Class Libraries
Ignore what it ways about targeting .Net 4.5. This is wrong. The package is all about using HttpClient in .Net 4.0. However, you may need to use VS2012 or higher. Not sure if it works in VS2010, but that may be worth testing.
