[C#]有关WebBrowser

WebBrowser窗口自动滚动

this.webBrowser.Document.Window.ScrollTo(0, webBrowser1.Document.Body.ScrollRectangle.Height);

WebBrowser的脚本出错信息

当页面上的脚本出错时,一般情况下会弹出脚本出错提示,如果在用WB写爬虫一类的时候,这类提示可能会导致系统不能工作,解决的发是:

(1)设置属性ScriptErrorsSurpressed = true;

(2)打开IE的设置 “Internet选项” - “高级” - 勾选”禁用脚本调试”

WebBrowser的内存释放

WB的内存开销很大,当连续打开很多网页时这个问题将会非常明显,甚至耗尽内存,解决的方我在MSDN论坛上找到(来源:http://social.msdn.microsoft.com/Forums/en-US/ieextensiondevelopment/thread/88c21427-e765-46e8-833d-6021ef79e0c8/),具体内容如下:

This solution worked for me!!
Thank you so much mike_t2e!!!!!!!———————————————————————–Is the memory released when you minimize the app ? If so, try this:– in class definition[DllImport(“KERNEL32.DLL”, EntryPoint = “SetProcessWorkingSetSize”, SetLastError = true, CallingConvention = CallingConvention.StdCall)]
internal static extern bool SetProcessWorkingSetSize(IntPtr pProcess, int dwMinimumWorkingSetSize, int dwMaximumWorkingSetSize);[DllImport(“KERNEL32.DLL”, EntryPoint = “GetCurrentProcess”, SetLastError = true, CallingConvention = CallingConvention.StdCall)]
internal static extern IntPtr GetCurrentProcess();

– code to call when you want to reduce the memory

IntPtr pHandle = GetCurrentProcess();
SetProcessWorkingSetSize(pHandle, -1, -1);
