C# 调用Web Api post提交json格式

    public static void sdf(string urls) {string url = urls;//定义request并设置request的路径WebRequest request = WebRequest.Create(url);request.Method = "post";//初始化request参数string postData = "{\"dataSource\":\"DataSource=192.168.0.70/orcl70;UserID=sde;PassWord=sde;\",\"type\":\"0\",\"whereCondition\":\"dlwz='国和百寿一村6号'\",\"tableName\":\"hzdzd_pt\"}";//var json = "{ \"dataSource\": \"Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.0.70)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl70)));User ID=sde;Password=sde;Unicode=True\" }";//设置参数的编码格式，解决中文乱码byte[] byteArray = Encoding.UTF8.GetBytes(postData);//设置request的MIME类型及内容长度request.ContentType = "application/json";request.ContentLength = byteArray.Length;//打开request字符流Stream dataStream = request.GetRequestStream();dataStream.Write(byteArray, 0, byteArray.Length);dataStream.Close();//定义response为前面的request响应WebResponse response = request.GetResponse();//获取相应的状态代码Console.WriteLine(((HttpWebResponse)response).StatusDescription);//定义response字符流dataStream = response.GetResponseStream();StreamReader reader = new StreamReader(dataStream);string responseFromServer = reader.ReadToEnd();//读取所有Console.WriteLine(responseFromServer);}
