想请教我是vs2012开发windows应用窗口程序，非web页面，现在想在服务器端作为数据库交互，客户端调用，请问在窗口程序中如何调用webapi?

这东西网上一堆一堆 /// <summary> /// GET请求与获取结果 /// </summary> public static string HttpGet(string Url, string postDataStr) { try { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url + (postDataStr == "" ? "" : "?") + postDataStr); request.Method = "GET"; request.ContentType = "text/html;charset=UTF-8"; request.Timeout = 10000; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream myResponseStream = response.GetResponseStream(); StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8); string retString = myStreamReader.ReadToEnd(); myStreamReader.Close(); myResponseStream.Close(); return retString; } catch (Exception ex) { return null; } } /// <summary> /// POST请求与获取结果 /// </summary> public static string HttpPost(string Url, string postDataStr) { try { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url); request.Method = "POST"; request.Timeout = 6000000; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = postDataStr.Length; StreamWriter writer = new StreamWriter(request.GetRequestStream(), Encoding.ASCII); writer.Write(postDataStr); writer.Flush(); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); string encoding = response.ContentEncoding; if (encoding == null || encoding.Length < 1) { encoding = "UTF-8"; //默认编码 } StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding)); string retString = reader.ReadToEnd(); return retString; } catch (Exception ex) { return null; } }

引用 2 楼 wang_peng_yl 的回复:

与webapi调用方式类似吗？

通过http请求访问啊。

一样的，分get 还是post, 如果是get就相当简单了 HttpGet('http://ww.abc.com/a/b/c?param1=1¶m2=2',""); 如果是post　HttpPost('http://ww.abc.com/a/b/c, "param1=1¶m2=2'); post我方法我忘了，好像是这样的
