使用System.Web.Webclient将自定义对象传递给Web方法的C#

using System.Web;
using System.Web.Script.Serialization;
using System.Net;

// 创建自定义对象
public class MyObject
{
    public string Name { get; set; }
    public int Age { get; set; }
}

// 实例化自定义对象
MyObject myObject = new MyObject();
myObject.Name = "John";
myObject.Age = 25;

// 将自定义对象转换为JSON字符串
JavaScriptSerializer serializer = new JavaScriptSerializer();
string jsonData = serializer.Serialize(myObject);

// 创建WebClient对象
using (WebClient client = new WebClient())
{
    // 设置请求的内容类型为"application/json"
    client.Headers[HttpRequestHeader.ContentType] = "application/json";

    // 发送POST请求，并将自定义对象作为请求的内容
    string response = client.UploadString("http://example.com/webmethod", "POST", jsonData);

    // 处理响应结果
    // ...
}
