c# webBrowser全掌握

一、获取网页源代码

1.不含有框架

string s=WB1.DocumentText;  //webbrowser1命名为WB1，下同

2.含有框架

引用mshtml;          //位置C:\Program Files\Microsoft.NET\Primary Interop Assemblies\Microsoft.mshtml.dll

object i_frame=0;     //第一个框架

IHTMLDocument2 doc = FWB.Document.DomDocument as IHTMLDocument2;

IHTMLFramesCollection2 frames = doc.frames as IHTMLFramesCollection2;

IHTMLWindow2 frame = frames.item(ref i_frame) as IHTMLWindow2;

IHTMLDocument2 frameDoc = frame.document as IHTMLDocument2;

string s=frameDoc.Document.body.innerHTML;

二、获取网页元素

1.根据ID

HtmlDocument ele=   WB1.Document.getElementById("元素的ID");

三、执行JS函数

1.用Navigate

WB1.Navigate("javascript:postComment();");    //postComment为要执行的JS函数

2.用IhtmlWindow2接口

IHTMLWindow2 win2 = WB1.Document.Window.DomWindow as IHTMLWindow2;

win2.execScript("function confirm(){return true;}", "javascript");

3.用IhtmlDocument2接口的parentWindow

IHTMLDocument2 doc2 = WB1.Document.DomDocument as IHTMLDocument2;

doc2.parentWindow.execScript("function confirm() {return true;}", "javascript");
