C # Sending a request with special characters will prevent the line

I am sending a request from one project to another:

WebRequest request = WebRequest.Create(UrlTemplate); request.Timeout = 500000; request.Method = WebRequestMethods.Http.Post; request.ContentType = ContentType; byte[] postData = System.Text.Encoding.ASCII.GetBytes(data); request.ContentLength = postData.Length; Stream newStream = request.GetRequestStream(); // Send the data. newStream.Write(postData, 0, postData.Length); newStream.Flush(); newStream.Close();

Well, in the function installed in UrlTemplate , I get the correct string (which I send to the data), but the problem starts when the string contains special characters.

If line: 12&34

What I get in the function: 12 .

If line: 12+34

What I get in the function: 12 34 .

I will be happy to know if this happened to some of you and how you decided it. Thanks in advance.

The problem is caused by the url-form Encoded string. (If it were just GET, I would say that it is encoded at the URL, but you are using POST.) The sign and sign have special meaning in the URL, and the + sign is used as a replacement for spaces.

See http://www.w3.org/TR/html401/interact/forms.html#h-17.13.3.3 for specifications. You will need to code them manually using UrlEncode () if you want the expected results.

Use System.Web.HttpUtility.UrlEncode or System.Net.WebUtility.UrlEncode when generating UrlTemplate

Use the URI.EscapeDataString () method in your password. This will help you read your special character correctly.
