我试图弄清楚如何在Word文档中突出显示带括号的文本，但是它具有嵌套的括号。我可以通过打开和关闭字符跟踪括号来遍历整个文档字符，但这在大型文档中效率不高。我想强调嵌套括号的另一种颜色。
[一些文本突出显示为黄色[其他突出显示为绿色]，另一些文本突出显示为黄色[另一项突出显示为绿色]，然后其余突出显示为黄色]
我最初使用的是该版本（vb.net），直到碰到了嵌套括号后才发现它：
'Toggles the highlighting of brackets in the document off and on
'Get Active document
Dim wdDoc As Word.Document
wdDoc = wdApp.ActiveDocument
'Set highlight color to yellow
wdApp.Options.DefaultHighlightColorIndex = Word.WdColorIndex.wdYellow
'Search for text between brackets and highlight text
With wdDoc.Content.Find
.ClearFormatting()
.Text = "\[*\]"
With .Replacement
.Text = ""
.ClearFormatting()
.Highlight = TogBtnBrackets.Checked
End With
.Forward = True
.Wrap = Word.WdFindWrap.wdFindContinue
.Format = True
.MatchWildcards = True
.Execute(Replace:=Word.WdReplace.wdReplaceAll)
End With
'Finished set wdDoc to nothing
wdDoc = Nothing
Dim Tog As String = ""
If TogBtnBrackets.Checked = True Then
Tog = "Highlighted"
TogBtnBrackets.Label = "Bracket Highlighting - On "
Else
Tog = "un-Highlighted"
TogBtnBrackets.Label = "Bracket Highlighting - Off"
End If
我发现了一些有关使用RegEx的事情，但是我真的不熟悉RegEx，似乎无法绕过它们。同样，您似乎也必须知道“嵌套”级别的数量才能编写正确的正则表达式，而我也不会总是知道这一点。

使用Word，您不不想要RegEx，因为它不尊重或不允许格式化。 Word的通配符功能相似，但不相同...
由于测试更加简单，因此我已经在VBA中为您完成了此任务。您需要进行一些小的更改（例如，在必要时添加wdAppp）才能在VB.NET中运行它。
由于必须测试首尾括号对是否包含其他首尾括号，因此无法使用Replace。因此，在每个成功的“查找”之后，代码将测试是否存在方括号。由于总会有一个实例，因此测试是循环执行的。
测试使用Instr来获取开括号的位置。对于第二个及以后的实例，Start的{{1}}位置设置为右括号的实例。一旦找不到更多内容，将应用突出显示，然后折叠范围，并在循环中再次执行Range。
我将测试放在一个单独的函数中，可以进行以下操作：1）测试任何字符（例如，方括号或括号），以及2）返回实例数，以防万一。 >

谢谢Cindy Meister，您的代码对我来说是个很好的起点。它对于获取嵌套的括号非常有用，但不会突出显示括号中的信息。我终于想出了VBA代码解决方案，稍后我将转到VB.NET。
