Get Local User Data

Get user data in bulk from locally cached data

  • API prototype
csharp/// <summary>
///Get user card of designated account in cache data
/// </summary>
/// <param name="accountIdList">List of user account IDs</param>
/// <param name="resultDelegate">Callback for querying results</param>
public static void GetUserNameCard(List<string> accountIdList, GetUserNameCardResultDelegate resultDelegate)
  • Example
csharpNIM.User.UserAPI.GetUserNameCard(new List<string>() { "id1","id2" }, OnGetNameCardCompleted);

private void OnGetNameCardCompleted(UserNameCard[] list)
    if (list != null && list.Any())
        //Query successfully, and process query results

Get User Data from the Server

User data is acquired from server and usually called when there is not local user data. After acquisition, SDK will update local database. 150 users can be acquired at most each time. The upper level may get user data in batch in the event of large quantity.

  • API prototype
csharp/// <summary>
///Query user card of designated account online
/// </summary>
/// <param name="accountIdList">List of user account IDs</param>
/// <param name="resultDelegate"></param>
public static void QueryUserNameCardOnline(List<string> accountIdList, GetUserNameCardResultDelegate resultDelegate)
  • Example
csharpNIM.User.UserAPI.QueryUserNameCardOnline(new List<string>() { "id1","id2" }, OnGetNameCardCompleted);

Notes: User data can be acquired from server in bulk via this interface. Considering user experience and flow cost, it is recommended not to invoke this interface frequently. For the pages under which the real-time performance requirement is not high, it is suggested to call the interface of reading local cache.

Update Personal Information

To update your user data, first construct theUserNameCardobject, then set the attributes that need to be updated, after that, callNIM.User.UserAPIUpdateMyCardto perform the update.

  • API prototype
csharp/// <summary>
/// Update user cards
/// </summary>
/// <param name="card"></param>
/// <param name="d"></param>
public static void UpdateMyCard(UserNameCard card, UpdateNameCardResultDelegate d)
  • Example
csharpprivate void UpdateMyInfo()
    UserNameCard card = new UserNameCard();
    card.AccountId = "MYSELF ID";
    card.Birthday = "1990.01.01";
    card.Email = "";
    card.Mobile = "123456789";
    card.NickName = "NEW NICKNAME";
    card.Signature = "SIGNATURE";
    card.Gender = 1;
    NIM.User.UserAPI.UpdateMyCard(_card, OnUpdateMyNamecard);

private void OnUpdateMyNamecard(ResponseCode response)
    //Process operation results

Notification for User Data Change

The event NIM.User.UserAPI.UserNameCardChangedHandler is registered to get notification for data change of all users.

  • Example
csharpNIM.User.UserAPI.UserNameCardChangedHandler += OnUserChanged;

private void OnUserChanged(object sender, UserNameCardChangedArgs e)
    //Process user data change. The parameter e includes detailed information of a user.

Except your "user data", SDK cannot ensure real-time information updating for other users. Other user data update occasion:

  • Call the interface QueryUserNameCardOnline to get user data online.

  • Receive messages from the user

  • When the program is start up again, information of friends will be synchronized.
