做推送封图的网站百度权重高的网站有哪些

        在日常使用电脑办公时，我们经常遇到需要截图然后保存图片，我们往往需要借助安装截图工具才能实现，现在我们通过C#自制截图工具，也能够轻松进行截图。

我们可以通过C#调用WindousAPI来实现截图，实例代码如下：

/// <summary>/// 调用API函数获取整个屏幕的图像/// </summary>/// <returns></returns>[DllImport("user32.dll", EntryPoint = "GetDesktopWindow")]private static extern IntPtr GetDesktopWindow();[DllImport("user32.dll", EntryPoint = "GetWindowDC")]private static extern IntPtr GetWindowDC(IntPtr hwnd);[DllImport("gdi32.dll", EntryPoint = "BitBlt")]private static extern int BitBlt(IntPtr hDestDC,int x,int y,int nWidth,int nHeight,IntPtr hSrcDC,int xSrc,int ySrc,int dwRop);/// <summary>/// 截取整个屏幕的图像/// </summary>/// <returns></returns>public static Bitmap CopyFromScreen(){int width = (int)SystemParameters.PrimaryScreenWidth;int height = (int)SystemParameters.PrimaryScreenHeight;Bitmap newBitmap = new Bitmap(width, height);Graphics g = Graphics.FromImage(newBitmap);IntPtr DeskHwnd = GetWindowDC(GetDesktopWindow());IntPtr Ghwnd = g.GetHdc();BitBlt(Ghwnd, 0, 0, width, height, DeskHwnd, 0, 0, 13369376);g.ReleaseHdc(Ghwnd);CopyHelper.newBitmap = newBitmap;return newBitmap;}
