There was such a problem: I ran the program many times and now it throws the following error FloodException: Flood prevention. Telegram now requires your program to do requests again only after 73611 seconds have passed (TimeToWait property). If you think the culprit of this problem may lie in TLSharp's implementation, open a Github issue please. I attach the code below:
using System;
using System.Text;
using System.Windows.Forms;
using TeleSharp.TL;
using TeleSharp.TL.Messages;
using TLSharp.Core;
namespace tgBM
{
public partial class Form1: Form
{
string phone;
string code;
int n = 1;
StringBuilder sb = new StringBuilder ();
TelegramClient client = new TelegramClient (2646156, "08ec188e0bdee432e568120348f5f13a"); // create a client with parameters
public Form1 ()
{
InitializeComponent();
}
string str = "";
public async void authAsync()
{
var dialogs = (TLDialogs) await client.GetUserDialogsAsync();
foreach (var element in dialogs.Chats)
{
TLChat chat = element as TLChat;
if (element is TLChannel)
{
var offset = 0;
TLChannel channel = element as TLChannel;
if (channel.Title == "TOPLES")
{
TLChannel ch = element as TLChannel;
TLInputPeerChannel inputPeer = new TLInputPeerChannel() {ChannelId = ch.Id, AccessHash = (long) ch.AccessHash};
while (n! = 11)
{
try
{
TLChannelMessages res = await client.SendRequestAsync <TLChannelMessages>
(new TLRequestGetHistory() {Peer = inputPeer, Limit = 20, AddOffset = offset, OffsetId = 0});
var msgs = res.Messages;
if (res.Count> offset)
{
offset + = msgs.Count;
foreach (TLAbsMessage msg in msgs)
{
if (msg is TLMessage)
{
TLMessage message = msg as TLMessage;
str + = n.ToString () + "\ t" + message.Id + "\ t" + message.FromId + "\ t" + message.Message + Environment.NewLine;
}
if (msg is TLMessageService)
continue;
n ++;
}
}
else
break;
}
catch (Exception ex)
{
MessageBox.Show (ex.Message);
break;
}
}
}
}
textBox3.Text = str;
}
}
private async void button1_Click (object sender, EventArgs e)
{
phone = textBox1.Text;
await client.ConnectAsync (); // make a connection
var hash = await client.SendCodeRequestAsync(phone);
}
private async void button2_Click (object sender, EventArgs e)
{
code = textBox2.Text;
var user = await client.MakeAuthAsync(phone, await client.SendCodeRequestAsync(phone), code);
authAsync();
}
}
}
