C#对指定的网页进行截图

碰到一个项目，需要对指定的网页进行截图保存，晕死！

需求永远都是怪异的.....

解决是关键～

遂写了以下代码，快准狠!（因为赶时间！）

可以实现对指定的页面获取，按指定的大小生成缩略图，当然也可以1：1的产生图，页面上的javascript 运行对截图貌似没任何影响，相当的正常，我个人都觉得很神奇。

首先对项目添加系统引用

System.Drawing;
System.Drawing.Design;
System.Windows.Forms;

获取指定网页并转换成图片的类：

using System;using System.Collections.Generic;using System.Text;using System.Drawing;using System.Drawing.Drawing2D;using System.Drawing.Imaging;using System.Windows.Forms;using System.Diagnostics;namespace MyLib  {    public class GetImage    {        private int S_Height;        private int S_Width;        private int F_Height;        private int F_Width;        private string MyURL;        public int ScreenHeight          {            get { return S_Height; }            set { S_Height = value; }        }        public int ScreenWidth          {            get { return S_Width; }            set { S_Width = value; }        }        public int ImageHeight          {            get { return F_Height; }            set { F_Height = value; }        }        public int ImageWidth          {            get { return F_Width; }            set { F_Width = value; }        }        public string WebSite        {            get { return MyURL; }            set { MyURL = value; }        }        public GetImage(string WebSite, int ScreenWidth, int ScreenHeight, int ImageWidth, int ImageHeight)        {            this.WebSite = WebSite;            this.ScreenWidth = ScreenWidth;            this.ScreenHeight = ScreenHeight;            this.ImageHeight = ImageHeight;            this.ImageWidth = ImageWidth;        }        public Bitmap GetBitmap()        {            WebPageBitmap Shot = new WebPageBitmap(this.WebSite, this.ScreenWidth, this.ScreenHeight);            Shot.GetIt();            Bitmap Pic = Shot.DrawBitmap(this.ImageHeight, this.ImageWidth);            return Pic;        }    }    class WebPageBitmap      {        WebBrowser MyBrowser;        string URL;        int Height;        int Width;        public WebPageBitmap(string url, int width, int height)        {            this.Height = height;            this.Width = width;            this.URL = url;            MyBrowser = new WebBrowser();            MyBrowser.ScrollBarsEnabled = false;            MyBrowser.Size = new Size(this.Width, this.Height);        }        public void GetIt()        {            MyBrowser.Navigate(this.URL);            while (MyBrowser.ReadyState != WebBrowserReadyState.Complete)            {                Application.DoEvents();            }        }        public Bitmap DrawBitmap(int theight, int twidth)        {            Bitmap myBitmap = new Bitmap(Width, Height);            Rectangle DrawRect = new Rectangle(0, 0, Width, Height);            MyBrowser.DrawToBitmap(myBitmap, DrawRect);            System.Drawing.Image imgOutput = myBitmap;            System.Drawing.Image oThumbNail = new Bitmap(twidth, theight, imgOutput.PixelFormat);            Graphics g = Graphics.FromImage(oThumbNail);            g.CompositingQuality = CompositingQuality.HighSpeed;            g.SmoothingMode = SmoothingMode.HighSpeed;            g.InterpolationMode = InterpolationMode.HighQualityBilinear;            Rectangle oRectangle = new Rectangle(0, 0, twidth, theight);            g.DrawImage(imgOutput, oRectangle);            try             {                return (Bitmap)oThumbNail;            }            catch (Exception ex)            {                return null;            }            finally             {                imgOutput.Dispose();                imgOutput = null;                MyBrowser.Dispose();                MyBrowser = null;            }        }    }}
