我想创建一个循环来检查我的Json对象上的条件。我正在寻找一种迭代我的json对象的方法:
JSON:
{"tasks":[
{
"id":-1,
"name":"Gantt editor",
"code":"",
"level":0,
"status":"STATUS_ACTIVE",
"start":1372608000000,
"duration":21,
"end":1375113599999,
"startIsMilestone":true,
"endIsMilestone":false,
"collapsed":false,
"assigs":[]
},
{
"id":"tmp_fk1372575559620",
"name":"release",
"code":"",
"level":1,
"status":"STATUS_ACTIVE",
"start":1372608000000,
"duration":1,
"end":1372694399999,
"startIsMilestone":false,
"endIsMilestone":false,
"collapsed":false,
"assigs":[]
}
], // number of tasks may vary
"selectedRow":8,
"deletedTaskIds":[],
"resources":
[
{
"id":"tmp_1",
"name":"Resource 1"
}
],
"roles":[
{
"id":"tmp_1",
"name":"Project Manager"
}
],
"canWrite":true,
"canWriteOnParent":true
}
我知道如何映射它,所以我假设我映射了Task和RootObject,如下所示:
public class Task
{
public object id { get; set; }
public string name { get; set; }
public string code { get; set; }
public int level { get; set; }
public string status { get; set; }
public object start { get; set; }
public int duration { get; set; }
public object end { get; set; }
public bool startIsMilestone { get; set; }
public bool endIsMilestone { get; set; }
public bool collapsed { get; set; }
public List<object> assigs { get; set; }
}
public class RootObject
{
public List<Task> tasks { get; set; }
public int selectedRow { get; set; }
public List<object> deletedTaskIds { get; set; }
public List<Resource> resources { get; set; }
public List<Role> roles { get; set; }
public bool canWrite { get; set; }
public bool canWriteOnParent { get; set; }
} // And etc .....
我知道如何手动检查任务,例如第一个
Rootobject project = JsonConvert.DeserializeObject<Rootobject>(jsonString);
Task task = project.tasks.FirstOrDefault(t => t.id == "-1");
decimal start = Convert.ToDecimal(task.start);
decimal end = Convert.ToDecimal(task.end);
decimal prog = Convert.ToDecimal(task.progress);
然后使用task来检查它的所有属性
如何查看所有任务?
提前致谢!

如果要遍历所有任务,可以使用:
foreach (var task in project.tasks)
{
// do some stuff
}
或者您可以使用LINQ过滤它们,如下所示:
foreach (var task in project.tasks.Where(t => t.id == "-1"))
{
// do some stuff
}
这与你的例子基本相同,唯一的区别是Where返回IEnumerable,而不仅仅是你的例子中的FirstOrDefault之类的任务。
