- p rivate void webBrowser_1_NewWindow(object sender, CancelEventArgs e)
- {
- WebBrowser webBrowser_temp = (WebBrowser)sender;

雖然這種方法能夠解決大部分的要求，但是治標不治本。
而且當網(wǎng)址里面還有漢字的時(shí)候就更加麻煩了，比如在百度MP3，歌曲名字都是漢字，和百度空間里面，大部分用戶(hù)名都是漢字，所以取的網(wǎng)址都用亂碼。雖然，可以對網(wǎng)址進(jìn)行編碼，但是并不是所有網(wǎng)頁(yè)都是uft-8編碼，對于如何得知網(wǎng)頁(yè)的編碼又是一個(gè)課題了。
最根本的方法就是重寫(xiě)了。
新建一個(gè)類(lèi)

---------------------另一方案下下----------------------
要解決這個(gè)問(wèn)題，可以使用下面的方法：
在日常的開(kāi)發(fā)中，大家有時(shí)需要用WebBrowser加載URL，來(lái)實(shí)現某些功能。而這時(shí)，我們就不希望所打開(kāi)的頁(yè)面中的鏈接，在新窗口中打開(kāi)，因為這樣的話(huà)，實(shí)際上是用系統默認的瀏覽器打開(kāi)了，從而脫離了你的WebBrowser，也就不能被你所控制了。
假設WebBrowser的Name是 webBrowser1
- ******* void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
- { //將所有的鏈接的目標，指向本窗體
- foreach (HtmlElement archor in this.webBrowser1.Document.Links)
- {
- archor.SetAttribute("target", "_self");
- } //將所有的FORM的提交目標，指向本窗體 foreach (HtmlElement form in this.webBrowser1.Document.Forms){ form.SetAttribute("target", "_self"); }}
- ******* void webBrowser1_NewWindow(object sender, CancelEventArgs e){ e.Cancel = true;}
記得將 WebBrowser 的 AllowWebBrowserDrop 設為 false
將 WebBrowser 的 WebBrowserShortcutsEnabled 設為 false
將 WebBrowser 的 IsWebBrowserContextMenuEnabled 設為 false
