HttpWebRequest

安装Json库

使用NuGet引用Newtonsoft.Json类库

代码

class Program
{
    static void Main(string[] args)
    {
        Stream streamResponse = null;
        StreamReader srResponse = null;
        Encoding encoding = Encoding.UTF8;

        HttpWebResponse response = null;
        HttpWebRequest request = null;

        request = WebRequest.Create(@"http://127.0.0.1:3333/webapi/user") as HttpWebRequest;
        CookieContainer cookieContainer = new CookieContainer();
        request.CookieContainer = cookieContainer;
        request.AllowAutoRedirect = true;
        request.Method = "GET";
        request.ContentType = "application/x-www-form-urlencoded";
        //request.ContentType = "application/xml";
        //request.Accept = "text/xml";
        response = request.GetResponse() as HttpWebResponse;
        streamResponse = response.GetResponseStream();
        srResponse = new StreamReader(streamResponse, encoding);
        string content = srResponse.ReadToEnd();
        List<User> users = JsonConvert.DeserializeObject<List<User>>(content);
        Console.WriteLine(users[0].UserName);

        Console.ReadKey();
    }

}

public class User
{
    public int Id { get; set; }

    public string UserName { get; set; }

    public DateTime CreateTime { get { return DateTime.Now; } }
}

设置返回编码格式为XML

request.Accept = "text/xml";
