从.NET控制台调用JSON WebService的最佳方法

我使用HttpWebRequest从Web服务中获取，该服务返回了一个JSON字符串。看起来像这样的GET：

// Returns JSON stringstring GET(string url) {    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);    try {        WebResponse response = request.GetResponse();        using (Stream responseStream = response.GetResponseStream()) { StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.UTF8); return reader.ReadToEnd();        }    }    catch (WebException ex) {        WebResponse errorResponse = ex.Response;        using (Stream responseStream = errorResponse.GetResponseStream())        { StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding("utf-8")); String errorText = reader.ReadToEnd(); // log errorText        }        throw;    }}

然后，我使用JSON.Net动态解析字符串。另外，您可以使用以下Codeplex工具从示例JSON输出静态生成C＃类：http
:
//jsonclassgenerator.preplex.com/

POST看起来像这样：

// POST a JSON stringvoid POST(string url, string jsonContent) {    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);    request.Method = "POST";    System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();    Byte[] byteArray = encoding.GetBytes(jsonContent);    request.ContentLength = byteArray.Length;    request.ContentType = @"application/json";    using (Stream dataStream = request.GetRequestStream()) {        dataStream.Write(byteArray, 0, byteArray.Length);    }    long length = 0;    try {        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { length = response.ContentLength;        }    }    catch (WebException ex) {        // Log exception and throw as for GET example above    }}

我在我们的Web服务的自动化测试中使用了这样的代码。
