如何使用ASP.NET中的按钮单击来调用类

Question

我有一个类需要在Asp.Net上点击按钮时调用。该类用于录制屏幕并将录制的文件保存在桌面上。

这是需要调用的类

    public class ScreenRecorder
{

private static string tempDir = Path.GetTempPath() + "/snapshot/";
private static System.Threading.Thread snap = new System.Threading.Thread(Snapshot);

private static System.Drawing.Rectangle _Bounds = System.Windows.Forms.Screen.PrimaryScreen.Bounds;
public static System.Drawing.Rectangle Bounds
{
    get { return _Bounds; }
    set { _Bounds = value; }
}

private static void Snapshot()
{
    if (!Directory.Exists(tempDir))
        Directory.CreateDirectory(tempDir);
    int Co = 0;
    do
    {
        Co += 1;
        System.Threading.Thread.Sleep(50);
        System.Drawing.Bitmap X = new System.Drawing.Bitmap(_Bounds.Width, _Bounds.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
        using(System.Drawing.Graphics G = System.Drawing.Graphics.FromImage(X)) {
            G.CopyFromScreen(_Bounds.Location, new System.Drawing.Point(), _Bounds.Size);
            System.Drawing.Rectangle CurBounds = new System.Drawing.Rectangle(System.Drawing.Point.Subtract(System.Windows.Forms.Cursor.Position,Bounds.Size), System.Windows.Forms.Cursor.Current.Size);
            System.Windows.Forms.Cursors.Default.Draw(G, CurBounds);
       }
        System.IO.FileStream FS = new System.IO.FileStream(tempDir + FormatString(Co.ToString(), 5, '0') + ".png", System.IO.FileMode.OpenOrCreate);
        X.Save(FS, System.Drawing.Imaging.ImageFormat.Png);
        X.Dispose();
        FS.Close();
    } while (true);
}

public static void ClearRecording()
{
    if (Directory.Exists(tempDir))
        Directory.Delete(tempDir, true);
        Directory.CreateDirectory(tempDir);
}

public static void Save(string Output)
{
    System.Windows.Media.Imaging.GifBitmapEncoder G = new System.Windows.Media.Imaging.GifBitmapEncoder();

    List<System.IO.FileStream> X = new List<System.IO.FileStream>();
    foreach (string Fi in Directory.GetFiles(tempDir, "*.png", SearchOption.TopDirectoryOnly))
    {
        System.IO.FileStream TempStream = new System.IO.FileStream(Fi, System.IO.FileMode.Open);
        System.Windows.Media.Imaging.BitmapFrame Frame = System.Windows.Media.Imaging.BitmapFrame.Create(TempStream);
        X.Add(TempStream);
        G.Frames.Add(Frame);
    }
    System.IO.FileStream FS = new System.IO.FileStream(Output, System.IO.FileMode.OpenOrCreate);
    G.Save(FS);
    FS.Close();

    foreach (System.IO.FileStream St in X)
    {
        St.Close();

    }

}

public static void Start()
{
    snap = new System.Threading.Thread(Snapshot);
    snap.Start();
}

public static void Stop()
{
    snap.Abort();
}

private static string FormatString(string S, int places, char character)
{
    if (S.Length >= places)
        return S;
    for (int X = S.Length; X <= places; X++)
    {
        S = character + S;
    }
    return S;
}

}

class Program
{
   static void Main(string[] args)
    {
    ScreenRecorder.Start();
    System.Threading.Thread.Sleep(5000);
    ScreenRecorder.Stop();
    ScreenRecorder.Save(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\\video.gif");
    ScreenRecorder.ClearRecording();
   }
  }

这是需要调用的类。这该怎么做？？对不起，如果问题似乎很愚蠢。我是初学者。在此先感谢!!
