我试图将这个Web服务集成到我的asp.net项目中,但它会弹出这种类型的错误！如果您对此有任何想法,请给我解决方案.有很多关于oodle web服务和oodle API的材料.

尝试使用此URL可以更好地了解我的问题
http://api.oodle.com/api/v2/listings?key=TEST&region=chicago&category=vehicle/car

解决方法

try
    {
        string url = @"http://api.oodle.com/api/v2/listings?key=TEST&region=chicago";

        WebClient webClient = new WebClient();
        webClient.Encoding = Encoding.UTF8;
        string result = webClient.DownloadString(url);

       }
  catch (Exception ex)
    {
        Response.Write(ex.ToString());

    }

该语句创建异常

string result = webClient.DownloadString(url);

和例外细节是

System.Net.WebException: Unable to connect to the remote server ---> 
System.Net.Sockets.SocketException: A connection attempt failed because the connected 
party did not properly respond after a period of time,or established connection failed 
because connected host has failed to respond 192.168.0.101:808 at
