C#实现快递api接口调用方法

无平台限制，依赖于快递api网接口

----------------实体类
[DataContract]
public class SyncResponseEntity
{
public SyncResponseEntity() { }
/// <summary>
/// 需要查询的快递代号
/// </summary>
[DataMember(Order = 0, Name = "id")]
public string ID { get; set; }
/// <summary>
/// 需要查询的快递名称
/// </summary>
[DataMember(Order = 1, Name = "name")]
public string Name { get; set; }
/// <summary>
/// 需要查询的快递单号
/// </summary>
[DataMember(Order = 2, Name = "order")]
public string Order { get; set; }
/// <summary>
/// 消息内容
/// </summary>
[DataMember(Order = 5, Name = "message")]
public string Message { get; set; }
/// <summary>

[DataMember(Order = 6, Name = "errcode")]
public string ErrCode { get; set; }
/// <summary>
/// 运单状态
/// </summary>
[DataMember(Order = 7, Name = "status")]
public int Status { get; set; }
/// <summary>
/// 跟踪记录
/// </summary>
[DataMember(Order = 8, Name = "data")]
public List<Order> Data { get; set; }
}
[DataContract(Name = "data")]
public class Order
{
public Order() { }
public Order(string time, string content)
{
this.Time = time;
this.Content = content;
}
[DataMember(Order = 0, Name = "time")]
public string Time { get; set; }
[DataMember(Order = 1, Name = "content")]
public string Content { get; set; }
}

基本上代码都在上面。在带www.kuaidiapi.cn上申请一个uid就大功告成。
