C#如何屏幕截图
//抓取带鼠标的桌面
private Bitmap CaptureDesktop()
{
try
{
int _CX = 0, _CY = 0;
Bitmap _Source = new Bitmap(GetSystemMetrics(0), GetSystemMetrics(1));
using (Graphics g = Graphics.FromImage(_Source))
{
g.CopyFromScreen(0, 0, 0, 0, _Source.Size);
g.DrawImage(CaptureCursor(ref _CX, ref _CY), _CX, _CY);
g.Dispose();
}
_X = (800 - _Source.Width) / 2;
_Y = (600 - _Source.Height) / 2;
return _Source;
}
catch
{
return null;
}
}//codego.net/tags/1/1/
//抓取没有鼠标的桌面
private Bitmap CaptureNoCursor()
{
Bitmap _Source = new Bitmap(GetSystemMetrics(0), GetSystemMetrics(1));
using (Graphics g = Graphics.FromImage(_Source))
{
g.CopyFromScreen(0, 0, 0, 0, _Source.Size);
g.Dispose();
}
return _Source;
}
//获取鼠标样式和坐标
private Bitmap CaptureCursor(ref int _CX, ref int _CY)
{
IntPtr _Icon;
CURSORINFO _CursorInfo = new CURSORINFO();
ICONINFO _IconInfo;
_CursorInfo.cbSize = Marshal.SizeOf(_CursorInfo);
if (GetCursorInfo(ref _CursorInfo))
{
if (_CursorInfo.flags == 0x00000001)
{
_Icon = CopyIcon(_CursorInfo.hCursor);
if (GetIconInfo(_Icon, out _IconInfo))
{
_CX = _CursorInfo.ptScreenPos.X - _IconInfo.xHotspot;
_CY = _CursorInfo.ptScreenPos.Y - _IconInfo.yHotspot;
return Icon.FromHandle(_Icon).ToBitmap();
}
}
}
return null;
}
//保存截图样式
string Cursor;
string PicPath;
private void button1_Click(object sender, EventArgs e)

try
{

截屏（带鼠标）
这份代码完整可运行的。
里面的代码应该都不用注释吧，从名字就能看出是什么功能。至于不懂得还是得多百度好。
