Question

//get user dialogs
var dialogs = await client.GetUserDialogsAsync() as TLDialogs;

//find channel by title
var chat = dialogs.Chats
                  .Where(c => c.GetType() == typeof(TLChat))
                  .Cast<TLChat>()
                  .FirstOrDefault(c => c.Title == "zgzxbhsrbhdrbh");

//send message
await client.SendMessageAsync(new TLInputPeerChannel() { ChannelId = chat.Id }, 
                                                         "OUR_MESSAGE");

我正在尝试此代码，但它返回了我InvalidOperationException：CHANNEL_INVALID。有人可以帮忙吗？

你说得很对。

//Get dialogs
 var dialogs = await client.GetUserDialogsAsync();

//get user chats 
   var chats = ((TeleSharp.TL.Messages.TLDialogsSlice)dialogs).Chats;

//find channel by title
   var tlChannel = chats.Where(_ => _.GetType() == typeof(TLChannel))
                        .Select(_=>(TLChannel)_)
                        .Where(_=>_.Title.Contains("<Channel-Name>"))
                        .FirstOrDefault();
//send message
    await client.SendMessageAsync(new TLInputPeerChannel()
                    { ChannelId = tlChannel.Id, AccessHash =(long)tlChannel.AccessHash },
                    "OUR_MESSAGE");

发送到群组和发送到频道是有区别的在你的代码中，在它的最后，你调用了一个命令来发送到一个通道，在第一个中，你将类型指定为一个组。这是最新的例外。你可以试试这个代码，上帝保佑，问题就解决了。

//get user dialogs
        var dialogs = (TLDialogsSlice)await client.GetUserDialogsAsync();
        //find channel by title
        var chat = dialogs.Chats
          .Where(c => c.GetType() == typeof(TLChat))
          .Cast<TLChat>()
          .FirstOrDefault(c => c.Title == "zgzxbhsrbhdrbh");

        //send message
        await client.SendMessageAsync(new TLInputPeerChat() { ChatId = chat.Id }, "OUR_MESSAGE");

TLSharp向群组发送消息
