无效令牌消息的原因

Question

在以下代码中，我收到了＃34;无效令牌＆＃34;错误信息。我关注this tutorial，但我不知道如何解决这个问题。

 class ConvertBitmap
    {
        [System.Runtime.InteropServices.DllImport("gdi32.dll")]
        public static extern bool DeleteObject(IntPtr handle);
        public static BitmapSource;
        public static IntPtr intPointer;
        public static BitmapSource BitmapToBitmapSource(System.Drawing.Bitmap bitmap)
        {
            intPointer = bitmap.GetHbitmap();

            bitmapSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(intPointer,
                IntPtr.Zero,

错误发生在这一行的末尾：

public static BitmapSource;

错误：
