我对使用 C # 和 JSON 数据相对较新,正在寻求指导。我使用的是 C # 3.0。NET3.5 SP1和 JSON.NET 3.5 r6。
我有一个定义好的 C # 类,需要从一个 JSON 结构中填充它。然而,并非从 Web 服务中检索到的条目的每个 JSON 结构都包含在 C # 类中定义的所有可能的属性。
我一直在做似乎是错误的,艰难的方法,只是从 JObject 中一个接一个地挑出每个值,然后将字符串转换成所需的类属性。
JsonSerializer serializer = new JsonSerializer();
var o = (JObject)serializer.Deserialize(myjsondata);
MyAccount.EmployeeID = (string)o["employeeid"][0];
将 JSON 结构反序列化为 C # 类并处理来自 JSON 源的可能丢失的数据的最佳方法是什么?
我的类被定义为:
public class MyAccount
{
[JsonProperty(PropertyName = "username")]
public string UserID { get; set; }
[JsonProperty(PropertyName = "givenname")]
public string GivenName { get; set; }
[JsonProperty(PropertyName = "sn")]
public string Surname { get; set; }
[JsonProperty(PropertyName = "passwordexpired")]
public DateTime PasswordExpire { get; set; }
[JsonProperty(PropertyName = "primaryaffiliation")]
public string PrimaryAffiliation { get; set; }
[JsonProperty(PropertyName = "affiliation")]
public string[] Affiliation { get; set; }
[JsonProperty(PropertyName = "affiliationstatus")]
public string AffiliationStatus { get; set; }
[JsonProperty(PropertyName = "affiliationmodifytimestamp")]
public DateTime AffiliationLastModified { get; set; }
[JsonProperty(PropertyName = "employeeid")]
public string EmployeeID { get; set; }
[JsonProperty(PropertyName = "accountstatus")]
public string AccountStatus { get; set; }
[JsonProperty(PropertyName = "accountstatusexpiration")]
public DateTime AccountStatusExpiration { get; set; }
[JsonProperty(PropertyName = "accountstatusexpmaxdate")]
public DateTime AccountStatusExpirationMaxDate { get; set; }
[JsonProperty(PropertyName = "accountstatusmodifytimestamp")]
public DateTime AccountStatusModified { get; set; }
[JsonProperty(PropertyName = "accountstatusexpnotice")]
public string AccountStatusExpNotice { get; set; }
[JsonProperty(PropertyName = "accountstatusmodifiedby")]
public Dictionary<DateTime, string> AccountStatusModifiedBy { get; set; }
[JsonProperty(PropertyName = "entrycreatedate")]
public DateTime EntryCreatedate { get; set; }
[JsonProperty(PropertyName = "entrydeactivationdate")]
public DateTime EntryDeactivationDate { get; set; }
}
要解析的 JSON 示例是:
{
"givenname": [
"Robert"
],
"passwordexpired": "20091031041550Z",
"accountstatus": [
"active"
],
"accountstatusexpiration": [
"20100612000000Z"
],
"accountstatusexpmaxdate": [
"20110410000000Z"
],
"accountstatusmodifiedby": {
"20100214173242Z": "tdecker",
"20100304003242Z": "jsmith",
"20100324103242Z": "jsmith",
"20100325000005Z": "rjones",
"20100326210634Z": "jsmith",
"20100326211130Z": "jsmith"
},
"accountstatusmodifytimestamp": [
"20100312001213Z"
],
"affiliation": [
"Employee",
"Contractor",
"Staff"
],
"affiliationmodifytimestamp": [
"20100312001213Z"
],
"affiliationstatus": [
"detached"
],
"entrycreatedate": [
"20000922072747Z"
],
"username": [
"rjohnson"
],
"primaryaffiliation": [
"Staff"
],
"employeeid": [
"999777666"
],
"sn": [

]
}
