清单 <Dictionary> foreach获得价值

Question

List<Dictionary<string, object>> data = new List<Dictionary<string, object>>();
Dictionary<string, Object> objs = new Dictionary<string, object>();
for (int i = 1; i <= onlineolanlar.Count; i++)
{
    objs.Add(i.ToString(), new userLevel() { UserID = userID.ToString(), Presence = UserLevelBul.ToString() });
}
foreach (var item5 in objs.Values)
{
    //How can I access item5 properties here??
}

Hi all,

How can I reach the values of that foreach loop?

item5 should have properties userid and userlevelbul but I can't reach them.

Answer 1

You declared your dictionary objs as Dictionary<string, object> . But in fact you only want to add (and later use) entries of type userLevel .

So simply declare the dictionary with the correct types:

Dictionary<string, userLevel> objs = new Dictionary<string, userLevel>();

Then you can use it straight forward:

foreach (var item5 in objs.Values)
{
     Console.WriteLine(item5.userID)
     Console.WriteLine(item5.Presence)
}

because now the elements in objs.Values as well as item5 are of type userLevel .

Answer 2

Either use userLevel with your Dictionary<string, Object> instead of Object or use Explicit casting (if you for some reason can't change object ):

foreach (var item5 in objs.Values)
{
     string userId = ((userLevel)item5).UserID;
     // or
     // string userId = (item5 as userLevel).UserID;
}
