Question

WebBrowser控件

C#中关于获取WebBrowser控件中的选中文本的实现，问题补充：我是想判断是否有选中文本才能判断是否能够进行复制或者粘贴。
谢谢，但是 我想知道 c#的实现！希望能得到帮助

Vb.net实现比较简单给你一段代码，C#的WebBrowser没有那个属性，所以不太好弄需要引用一个com组件。我也没有弄出来。
Option Strict Off
Option Explicit On
Friend Class Form1
Inherits System.Windows.Forms.Form
Private Sub Command1_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Command1.Click
Dim objSelection As Object
Dim objTxtRange As Object

objSelection = WebBrowser1.Document.DomDocument.selection
If Not (objSelection Is Nothing) Then

objTxtRange = objSelection.createRange
If Not (objTxtRange Is Nothing) Then

MessageBox.Show(objTxtRange.htmlText)

objTxtRange = Nothing
End If

objSelection = Nothing
End If
End Sub

Private Sub Form1_Load(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate(New System.URI("http://www.baidu.com"))
End Sub
End Class
