c# - 使用 ArraySegment 类到 JSON 对象

Question

我想解决这个问题，

我想使用 ArraySegment 传输 Json 对象

我的 JSON 数据是以这种格式

{"employees":[
    {"firstName":"John", "lastName":"Doe"},
    {"firstName":"Anna", "lastName":"Smith"},
    {"firstName":"Peter", "lastName":"Jones"}
]}

我用过this创建指定类的工具，如

public class Employee
{
    public string firstName { get; set; }
    public string lastName { get; set; }
}

public class RootObject
{
    public List<Employee> employees { get; set; }
}

现在我像这样将数据插入到对象中

var objectToSerialize = new RootObject();
objectToSerialize.items = new List<Employee> 
          {
             new Item { firstName="abc", lastName="xyz"},
             new Item { firstName="pqr", lastName="stu"}
          };

但现在我遇到了问题，我不知道如何使用网络套接字

通过这个

ArraySegment<byte> max = new ArraySegment<byte>(, , );
await webSocket.SendAsync(max, WebSocketMessageType.Text, true, CancellationToken.None);

您需要先将objectToSerialize 序列化为一个字节缓冲区

var data = JsonConvert.SerializeObject(objectToSerialize);
var encoded = Encoding.UTF8.GetBytes(data);
var buffer = new ArraySegment<Byte>(encoded, 0, encoded.Length);
await webSocket.SendAsync.SendAsync(buffer, WebSocketMessageType.Text, true, CancellationToken.None);
