try 
    { 
     // System.Drawing.Point p=new System.Drawing.Point(100,500); 
     Bitmap b = new Bitmap(System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width, System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height); 
     Graphics graphics=Graphics.FromImage(b as Image); 
     graphics.CopyFromScreen(0,0,0,0,b.Size); 

     string stringsFile=@"C:\Image1"; 

     b.Save(stringsFile,ImageFormat.Png); 
    } 
    catch (Exception exp) 
     { 
     Microsoft.Windows.Controls.MessageBox.Show("Opps !!! " + exp.Message); 
     }

您可以使用此代碼

/// Gets a JPG "screenshot" of the current UIElement 
    /// 
    /// UIElement to screenshot 
    /// Scale to render the screenshot 
    /// JPG Quality 
    /// Byte array of JPG data 
    public static byte[] GetJpgImage(this UIElement source, double scale, int quality) 
    { 
     double actualHeight = source.RenderSize.Height; 
     double actualWidth = source.RenderSize.Width; 

     double renderHeight = actualHeight * scale; 
     double renderWidth = actualWidth * scale; 

     RenderTargetBitmap renderTarget = new RenderTargetBitmap((int) renderWidth, (int) renderHeight, 96, 96, PixelFormats.Pbgra32); 
     VisualBrush sourceBrush = new VisualBrush(source); 

     DrawingVisual drawingVisual = new DrawingVisual(); 
     DrawingContext drawingContext = drawingVisual.RenderOpen(); 

     using (drawingContext) 
     { 
      drawingContext.PushTransform(new ScaleTransform(scale, scale)); 
      drawingContext.DrawRectangle(sourceBrush, null, new Rect(new Point(0, 0), new Point(actualWidth, actualHeight))); 
     } 
     renderTarget.Render(drawingVisual); 

     JpegBitmapEncoder jpgEncoder = new JpegBitmapEncoder(); 
     jpgEncoder.QualityLevel = quality; 
     jpgEncoder.Frames.Add(BitmapFrame.Create(renderTarget)); 

     Byte[] _imageArray; 

     using (MemoryStream outputStream = new MemoryStream()) 
     { 
      jpgEncoder.Save(outputStream); 
      _imageArray = outputStream.ToArray(); 
     } 

     return _imageArray; 
    }
