截取活动窗体程序

在console application中,采用快捷键,成功截取界面活动窗体程序.

与大家分享.

 

class shotWindowsUtility { /// <summary> /// 截取活动窗体 /// </summary> /// <param name="picPath"></param> /// <param name="picName"></param> /// <param name="picFormat"></param> public static void shotActiveWindows(string picPath, string picName, string picFormat) { string saveStr = picPath + @"/" + picName + @"." + picFormat; SendKeys.SendWait("%{PRTSC}"); Thread.Sleep(2000); Console.WriteLine(saveStr); if (Clipboard.GetDataObject() != null) { IDataObject d = Clipboard.GetDataObject(); Bitmap b = (Bitmap)d.GetData(DataFormats.Bitmap); b.Save(saveStr); Thread.Sleep(2000); Console.WriteLine("find"); } else { Console.WriteLine("not find"); } } }

 

类shotWindowsUtility,为截取窗体类.

 

下面是调用截图类的main函数.

 

class Program { [STAThread] // for OLE static void Main(string[] args) { Process cmd = new Process(); cmd.StartInfo.FileName = "cmd"; cmd.StartInfo.RedirectStandardOutput = true; cmd.StartInfo.RedirectStandardInput = true; cmd.StartInfo.UseShellExecute = false; //cmd.StartInfo.CreateNoWindow = false; cmd.Start(); try { string dir = "explorer" + @" D:/"; cmd.StandardInput.WriteLine(dir); cmd.Close(); } catch (Exception e) { Console.WriteLine("start erro"); return; } Thread.Sleep(1000); string path = @"D:"; string name = "test"; string format = "bmp"; shotWindowsUtility.shotActiveWindows(path, name, format); Console.ReadKey(); } }

 

在main函数中注意[STAThread],只有加上这句,在console application中才可以得到clipboard中的图片数据.

 

以上代码,在vs2008中测试通过.
