Server.UrlEncode和HttpUtility.UrlEncode之间有区别吗？

我正在尝试将URL编码的帖子发送到用PHP实现的REST API.POST数据包含两个用户提供的字符串:

WebRequest request = HttpWebRequest.Create(new Uri(serverUri, "rest"));
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
request.Headers.Add("Content-Transfer-Encoding", "binary");

// Form the url-encoded credentials we'll use to log in
StringBuilder builder = new StringBuilder();
builder.Append("user=");
builder.Append(user);
builder.Append("&password=");
builder.Append(password);
byte[] credentials = Encoding.UTF8.GetBytes(builder.ToString());

// Write the url-encoded post data into the request stream.
request.ContentLength = credentials.Length;
using (Stream requestStream = request.GetRequestStream()) {
  requestStream.Write(credentials, 0, credentials.Length);
}

这会向包含user=myusername&password=mypasswordUTF-8 的服务器发送HTTP请求作为其POST数据.

如何逃避用户提供的字符串？例如,如果我有一个名为的用户big&mean,那么如何对&符号进行转义,以免它弄乱请求行？
