我刚刚开始在VB.NET中查看语法高亮的一些示例,并且它的工作非常不错。但是,有没有办法检查另一个文本中的某些文本?例如,如果我希望" "
突出显示为橙色,那么工作正常。但是如果我希望" "
内的任何文字都是蓝色的呢?有没有办法只检查里面的文字?我目前的代码(不是我的,来自here
Private Sub RichTextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged
' Dim
Dim brackets As New List(Of String)
' AQUA
brackets.Add("<")
brackets.Add(">")
brackets.Add("/>")
brackets.Add("</")
Dim tags As New List(Of String)
' LIME GREEM
tags.Add("html")
tags.Add("title")
tags.Add("head")
If RichTextBox1.Text.Length > 0 Then
Dim selectStart As Integer = RichTextBox1.SelectionStart
RichTextBox1.Select(0, RichTextBox1.Text.Length)
RichTextBox1.SelectionColor = Color.Black
RichTextBox1.DeselectAll()
For Each oneWord As String In brackets
Dim pos As Integer = 0
Do While RichTextBox1.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) >= 0
pos = RichTextBox1.Text.ToUpper.IndexOf(oneWord.ToUpper, pos)
RichTextBox1.Select(pos, oneWord.Length)
RichTextBox1.SelectionColor = Color.Aqua
pos += 1
Loop
Next
For Each tagWord As String In tags
Dim pos As Integer = 0
Do While RichTextBox1.Text.ToUpper.IndexOf(tagWord.ToUpper, pos) >= 0
pos = RichTextBox1.Text.ToUpper.IndexOf(tagWord.ToUpper, pos)
RichTextBox1.Select(pos, tagWord.Length)
RichTextBox1.SelectionColor = Color.LimeGreen
pos += 1
Loop
Next
RichTextBox1.SelectionStart = selectStart
End If
End Sub
我没有使用&#34; &#34;例如,但是我们想要用&lt;取代。有办法吗?
