Overview
In some cases, you may need to group conversations, for example, into a "Product experience" or "R&D" group, which can be implemented through the following API.
Note
To use this feature, you need to purchase the Premium edition.
This feature is supported only on the enhanced edition on native SDK 6.5 or later.
Conversation Group
Creating a conversation group
Call the ConvCreateConversationGroup (details) API to create a conversation group.
Note
Up to 20 conversation groups can be created. After this limit is exceeded, the 51010 error will be reported. Groups that are no longer used should be promptly deleted.
Attribute
Definition
Description
groupName
Conversation group name
It must be greater than 0 in length and can contain up to 32 bytes; otherwise, the 51011 error will be reported.
conversationIDList
List of conversation IDs
It cannot be empty.
Sample code:
    // Create a conversation group
    TIMResult res = TencentIMSDK.ConvCreateConversationGroup("groupName", new List<string> {
      conv_id
    }, (int code, string desc, List<ConversationOperationResult> results, string user_data)=>{
      // Async result of the conversation group creation
    });
Deleting a conversation group
Call the ConvDeleteConversationGroup (details) API to delete a conversation group.
Note
 If the target conversation group doesn't exist, the 51009 error will be reported.
Sample code:
    // Delete the conversation group
    TIMResult res = TencentIMSDK.ConvDeleteConversationGroup("groupName", (int code, string desc, string result, string user_data)=>{
      // Async result of the conversation group deletion
    });
Renaming a conversation group
Call the ConvRenameConversationGroup (details) API to rename a conversation group.
Sample code:
    // Rename a conversation group
    TIMResult res = TencentIMSDK.ConvRenameConversationGroup("oldGroupName", "newGroupName", (int code, string desc, string result, string user_data)=>{
      // Async result of the conversation group renaming
    });
Getting the list of conversation groups
Call the ConvGetConversationGroupList (details) API to get the list of conversation groups.
Sample code:
    // Get the list of conversation groups
    TIMResult res = TencentIMSDK.ConvGetConversationGroupList((int code, string desc, List<string> results, string user_data)=>{
      // Async result of the conversation group list getting
    });
To get the list of conversations under a group, you can call the ConvGetConversationListByFilter (details) API.
Sample code:
    // Get the conversation list
    ConversationListFilter filter = new ConversationListFilter
    {
        conversation_list_filter_conv_type: TIMConvType.kTIMConv_C2C,// Conversation type
        conversation_list_filter_mark_type: TIMConversationMarkType.kTIMConversationMarkTypeStar,// Conversation mark type
        conversation_list_filter_conversation_group: "groupName"// Named of the group whose data is to be pulled
    };
    ulong next_seq = 0; // Pulling cursor
    uint count = 10; // Pulling count
    // Advanced API for getting the conversation list
    TIMResult res = TencentIMSDK.ConvGetConversationListByFilter(filter, next_seq, count, (int code, string desc, ConversationListResult result, string user_data)=>{
      // Async result of the conversation list getting
      if (code == 0) {
        // Pulled successfully
        bool isFinished = result.conversation_list_result_is_finished; // Whether pulling is completed
        next_seq = result.conversation_list_result_next_seq; // Cursor for subsequent paged pulling
        var conversationList = result.conversation_list_result_conv_list; // List of messages pulled this time
        // If more conversations need to be pulled, use the returned `nextSeq` to continue pulling until `isFinished` is `true`.
      }
    });
Adding a conversation to a group
After a group is created, you can call the ConvAddConversationsToGroup (details) API to add a conversation to the group.
Sample code:
    // Add a conversation to a conversation group
    TIMResult res = TencentIMSDK.ConvAddConversationsToGroup("groupName", new List<string> {
      conv_id
    }, (int code, string desc, List<ConversationOperationResult> results, string user_data)=>{
      // Async result of adding a conversation to a conversation group
    });
Deleting a conversation from a group
Call the ConvDeleteConversationsFromGroup (details) API to delete a conversation from a group.
Sample code:
    // Delete a conversation from a conversation group
    TIMResult res = TencentIMSDK.ConvDeleteConversationsFromGroup("groupName", new List<string> {
      conv_id
    }, (int code, string desc, List<ConversationOperationResult> results, string user_data)=>{
      // Async result of deleting a conversation from a conversation group
    });
Listening for the notification of a conversation group change
Call the SetConvEventCallback (details) API to listen for conversation group change notifications.
Sample code:
    // Set the conversation listener
    TencentIMSDK.SetConvEventCallback((TIMConvEvent conv_event, List<ConvInfo> conv_list, string user_data)=>{
      // Process the callback logic
    });
