我尝试序列化json,但得到错误.
An exception of type
‘Newtonsoft.Json.JsonException’ occurred in Newtonsoft.Json.dll but was not handled in user codeAdditional information: Error creating ‘LinkListOfUserGroup’.
我该怎么做才能获得[]空列表,“”对于空字符串和整数？
UserRequestJson user = new UserRequestJson()
{
Email = _Name + "@email.com",
UserName = _Name,
Password = _Name + "!",
PasswordQuestion= _Name,
PasswordAnswer= _Name,
Groups = new GERLinkListOfUserGroup()
{
NewItems = new List<NameIDItem>() { new NameIDItem("HCS Users", groupID) },
RemovedItems = new List<NameIDItem>(),
TrackChanges = false,
Items = new List<NameIDItem>() { new NameIDItem("HCS Users", groupID) }
},
Name=_Name,
ConfirmPassword= _Name + "!"
};
string json= JsonConvert.SerializeObject(user);
Console.WriteLine(json);
{"Email":"asdasd2@mail.com","Email2":"","Email3":"","UserName":"!asfsfsd","Password":"!asdasd!asdasd","PasswordQuestion":"!asdasd","PasswordAnswer":"!asdasd","IsAdmin":false,"Source":0,"MustResetPassword":false,"CellPhoneNo":"","CellPhoneNo2":"","CellPhoneNo3":"","PagerNo":"","PagerNo2":"","NotifyBySMS":false,"NotifyByEmail":false,"NotifyByPopup":false,"NotifyByPush":false,"AllowPersonalDashboard":false,"AllowUnlimitedDashboardItems":false,"CanHaveUnlimitedAlerts":false,"StayLoggedIn":true,"IsActive":false,"AccountTypeID":1,"Groups":{"NewItems":[],"RemovedItems":[],"TrackChanges":false,"Items":[]},"CreatedBy":0,"CreatedOn":"0001-01-01T00:00:00","ModifiedBy":0,"ModifiedOn":"0001-01-01T00:00:00","ID":0,"Name":"!asdasd","ConfirmPassword":"!asdasd!asdasd","CellProviderID":"","CellProviderID2":"","CellProviderID3":"","PagerProviderID":"","PagerProviderID2":""}
解决方法:
您没有LinkListOfUserGroup中任何属性的[JsonProperty]属性,这就是它失败的原因.
[JsonObject(MemberSerialization.OptIn)]
public class LinkListOfUserGroup
{
[JsonProperty]
public List<NameIDItem> NewItems { get; set; }
[JsonProperty]
public List<NameIDItem> RemovedItems { get; set; }
[JsonProperty]
public bool TrackChanges { get; set; }
[JsonProperty]
public List<NameIDItem> Items { get; set; }
}
应该做的伎俩.
