推荐答案

我想您正在尝试调用基于REST的服务，该服务将返回Json数据.

首先检查有效的REST服务网址.如果您的REST服务网址正确，请尝试通过以下代码调用服务.

I guess you are trying to Call REST based service which will return Json Data.

Firstly check for valid REST Service Url. If your REST Service url is correct then try calling service by below code.

string apiUrl = "YourFullServiceUrl";
Uri address = new Uri(apiUrl);

// Create the web request 
System.Net.HttpWebRequest request = System.Net.WebRequest.Create(address) as System.Net.HttpWebRequest;
request.Method = "GET";
request.ContentType = "text/json";

using (System.Net.HttpWebResponse response = request.GetResponse() as System.Net.HttpWebResponse)
{
// Get the response stream 
System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream());

string strOutput = reader.ReadToEnd();
}
