RichTextBox1.SelectAll
【vb.net代码高亮 vbnet progressbar】RichTextBox1.SelectionColor = Color.Black
If Regex.IsMatch(RichTextBox1.Text, "\bDim\b") = True Then
For Each mat As Match In Regex.Matches(RichTextBox1.Text, "\bDim\b")
RichTextBox1.SelectionStart = mat.Index
RichTextBox1.SelectionLength = mat.Length
RichTextBox1.SelectionColor = Color.YellowGreen
Next
End If
RichTextBox1.SelectionStart = pos
RichTextBox1.SelectionLength = 0
End Sub
