C# ProgressBar Control

Remaetanju•6mo ago

MegaApiClient client = new MegaApiClient();
client.LoginAnonymous();
Uri fileLink = new Uri(packurl);

INode node = client.GetNodeFromLink(fileLink);
using (var downloadStream = client.Download(node))
using (var progressionStream = new ProgressionStream(downloadStream, x => HERE.button1_Click())) /* <=== CLICK ON BUTTON INSTEAD OF ConsoleWriteLine
(NOT SURE THIS WORKS?)
*/
using (var fileStream = new FileStream(LCGamePath + "\\" + packname, FileMode.Create))
{
    progressionStream.CopyTo(fileStream);
}

client.Logout();

MegaApiClient client = new MegaApiClient();
client.LoginAnonymous();
Uri fileLink = new Uri(packurl);

INode node = client.GetNodeFromLink(fileLink);
using (var downloadStream = client.Download(node))
using (var progressionStream = new ProgressionStream(downloadStream, x => HERE.button1_Click())) /* <=== CLICK ON BUTTON INSTEAD OF ConsoleWriteLine
(NOT SURE THIS WORKS?)
*/
using (var fileStream = new FileStream(LCGamePath + "\\" + packname, FileMode.Create))
{
    progressionStream.CopyTo(fileStream);
}

client.Logout();

now with the code upper the object HERE is of type Form1, and i run it before the snippet and then give his public button_1click()
