我尝试过：

How to stop web client downloading process and save it
and after that reset the process again

I don't want return downloading process to start I want to save it

What I have tried:

void start()
    {
        Uri source = new Uri(comboBox1.Text);
        file = source.ToString();
        button1.Text = "Stop";
        wc.OpenRead(source);
        path = comboBox2.Text;
        wc.DownloadProgressChanged += (s, z) =>
        {
            label3.Text = $"Downloaded as MB: {((float)z.BytesReceived / 1048576).ToString("#.#")}";
            label4.Text = $"Downloaded {z.ProgressPercentage}%";
            progressBar1.Value = z.ProgressPercentage;
            timer1.Start();
        };
        wc.DownloadFileAsync(source, path + Path.GetFileName(source.ToString()));
        button3.Visible = true;
    }
    void stop()
    {
        wc.CancelAsync();
        button1.Text = "Start";
    }

推荐答案

下载为MB：{（（float）z.BytesReceived / 1048576）。的ToString（ ##）};
label4.Text =

"Downloaded as MB: {((float)z.BytesReceived / 1048576).ToString("#.#")}"; label4.Text =

Downloaded {z.ProgressPercentage}％;
progressBar1.Value = z.ProgressPercentage;
timer1.Start（）;
};
wc.DownloadFileAsync（source，path + Path.GetFileName（source.ToString（）））;
button3.Visible = true;
}
void stop（）
{
wc.CancelAsync（）;
button1.Text =开始;
}

"Downloaded {z.ProgressPercentage}%"; progressBar1.Value = z.ProgressPercentage; timer1.Start(); }; wc.DownloadFileAsync(source, path + Path.GetFileName(source.ToString())); button3.Visible = true; } void stop() { wc.CancelAsync(); button1.Text = "Start"; }
