如何在WebBrowser控件中注入CSS
如何在WebBrowser控件中注入CSS
提问于 2019-05-13 20:47:50
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
webBrowser1.Navigate("https://www.aparat.com/aleffamily/live2");
webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
}
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
HtmlElement head = webBrowser1.Document.GetElementsByTagName("head")[0];
HtmlElement styleEl = webBrowser1.Document.CreateElement("style");
IHTMLStyleElement element = (IHTMLStyleElement)styleEl.DomElement;
IHTMLStyleSheetElement styleSheet = element.styleSheet;
styleSheet.cssText = @"body {background-color:transparent !important; margin: 0px auto; overflow: hidden; }.live__content{display:none;}.chat__footer{display:none;}.chat__header{display:none}#header{display:none}.in-chat-avatar{display:none}.message__username{font-style:italic;font-weight: 800!important;color:ff8f0f !important}.message__text{font-style:italic;font-weight: 400!important;color:ff8f0f !important}.chat__content{ background-color:transparent !important}.chat{ background-color:transparent !important}";
head.AppendChild(styleEl);
}
}}
这段代码对我不起作用，我得到了这个错误
错误1找不到类型或命名空间名称“IHTMLStyleSheetElement”(是否缺少using指令或程序集引用？)C:\Users\aleffamily\documents\visual studio 2010\Projects\WindowsFormsApplication1\WindowsFormsApplication1\Form1.cs 30 13 WindowsFormsApplication1

您试图在IHTMLStyleElement和IHTMLStyleSheetElement中引用什么？它不是.NET框架中的任何地方。
只需修改代码以编写泛型HtmlElement类型的内容，即可使用样式表编写.InnerText或.InnerHtml的内容
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
webBrowser1.Navigate("https://www.aparat.com/aleffamily/live2");
webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
}
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
HtmlElement head = webBrowser1.Document.GetElementsByTagName("head")[0];
HtmlElement styleEl = webBrowser1.Document.CreateElement("style");
styleEl.InnerHtml = @"body {background-color:transparent !important; margin: 0px auto; overflow: hidden; }.live__content{display:none;}.chat__footer{display:none;}.chat__header{display:none}#header{display:none}.in-chat-avatar{display:none}.message__username{font-style:italic;font-weight: 800!important;color:ff8f0f !important}.message__text{font-style:italic;font-weight: 400!important;color:ff8f0f !important}.chat__content{ background-color:transparent !important}.chat{ background-color:transparent !important}";
head.AppendChild(styleEl);
}
