Question

在文本的特定部分应用删除线的最简单方法是什么？

例如：

Answer 1

'rxtTest = My WinForm RichTextBox
'rxtTest.Text = "Stackoverflow is a very good site"
'text selected = "very"

Private Sub rxtTest_MouseCaptureChanged(sender As System.Object, e As System.EventArgs) Handles rxtTest.MouseCaptureChanged
    Dim f As New System.Drawing.Font("Arial", 12, FontStyle.Strikeout)
    rxtTest.SelectionFont = f
End Sub

'After this code my text selected ("very") will be strikeout
