从JSON对象中删除特定属性
我有一个JSON:
{ "scbs_currentstatus": "",
"scbs_primaryissue": "",
"_umb_id": "Test",
"_umb_creator": "Admin",
"_umb_createdate": "0001-01-01 00:00:00",
"_umb_updatedate": "0001-01-01 00:00:00",
"_umb_doctype": "Test",
"_umb_login": "Test",
"_umb_email": "Test",
"_umb_password": {
"newPassword": "Test",
"oldPassword": null,
"reset": null,
"answer": null
},
"_umb_membergroup": {
" User": false,
"Line User": true,
"Callback User": false,
"Su User": false,
},
"umbracoMemberComments": "Test",
"umbracoMemberFailedPasswordAttempts": ""
}
我试图删除所有以 开头的属性。这在json.net中可能吗?
输出将是这样的:
{ "scbs_currentstatus": "",
"scbs_primaryissue": "",
"umbracoMemberComments": "Test",
"umbracoMemberFailedPasswordAttempts": ""
}
使用删除我能够做到,但是不能一次全部完成。
result.Property("_umb_id").Remove();
有什么建议吗?
回答:
您可以先解析字符串:
var temp = JArray.Parse(json);temp.Descendants()
.OfType<JProperty>()
.Where(attr => attr.Name.StartsWith("_umb_"))
.ToList() // you should call ToList because you're about to changing the result, which is not possible if it is IEnumerable
.ForEach(attr => attr.Remove()); // removing unwanted attributes
json = temp.ToString(); // backing result to json
或:
result.Properties() .Where(attr => attr.Name.StartsWith("_umb_"))
.ToList()
.ForEach(attr => attr.Remove());
您可以在where
子句中指定更多条件:
.Where(attr => attr.Name.StartsWith("_umb_") && some_other_condition)
要么
.Where(attr => attr.Name.StartsWith("_umb_") || some_other_condition)
或任何您需要的。
