【问题描述】:
我在使用 Microsoft.Office.Interop.Word 时遇到问题 - 尝试通过格式设计更改执行查找和替换。
这里最令人沮丧的是我没有收到错误,只是 Word 应用程序卡住了。
我正在检查如何在Interop Word 上使用Find.Execute,因为它需要通过Object - 我无法弄清楚这样做的正确方法是什么,我在探索这个问题时发现了不同的方法。
让我们假设我有这种代码:
using msWord = Microsoft.Office.Interop.Word;
msWord.Document doc = msWord.Application.ActiveDocument; // sets the document
Range range = doc.StoryRanges[WdStoryType.wdMainTextStory]; // sets the range as the main text
string textToFind = "ABC"; // the text to be found
string textToReplace = "123"; // the text to replace with
bool useWildCards = false; // whether to use wildcards on search
bool makeBold = true; // whether to change the font format to bold or non-bold
现在我正在执行这样的查找和替换功能:
FindAndReplaceWithFormating(range ,textToFind ,textToReplace, useWildCards, makeBold)
现在我的问题是如何以正确和最合适的方法使这个FindAndReplaceWithFormating 函数。为此,我有 3 种不同的方法:
private void FindAndReplaceWithFormating(Range range, string textToFind,
string textToReplace, bool useWildCards, bool makeBold)
{
range.Find.ClearFormatting();
range.Find.Replacement.ClearFormatting();
range.Find.Replacement.Font.Bold = makeBold; // the format design must come like this.
// here comes the rest of the code according to the chosen method...
}
方法一:
range.Find.Text = textToFind;
range.Find.Replacement.Text = textToReplace;
range.Find.MatchWildcards = useWildCards;
range.Find.Forward = true;
range.Find.Format = true;
range.Find.Wrap = msWord.WdFindWrap.wdFindContinue;
object replaceAll = msWord.WdReplace.wdReplaceAll;
object missing = Missing.Value; // using System.Reflection;
// all ref are missing. only replaceAll ref is sent
range.Find.Execute(ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing,
ref replaceAll, ref missing, ref missing, ref missing, ref missing);
方法二:
object missing = Missing.Value;
object FindText = textToFind;
object MatchCase = missing;
object MatchWholeWord = missing;
object MatchWildcards = useWildCards;
object MatchSoundsLike = missing;
object MatchAllWordForms = missing;
object Forward = true;
object Wrap = msWord.WdFindWrap.wdFindContinue;
object Format = true;
object ReplaceWith = textToReplace;
object Replace = msWord.WdReplace.wdReplaceAll;
object MatchKashida = missing;
object MatchDiacritics = missing;
object MatchAlefHamza = missing;
object MatchControl = missing;
// all are sent as object.
find.Execute(ref FindText, ref MatchCase, ref MatchWholeWord, ref MatchWildcards, ref MatchSoundsLike,
ref MatchAllWordForms, ref Forward, ref Wrap, ref Format, ref ReplaceWith, ref Replace,
ref MatchKashida, ref MatchDiacritics, ref MatchAlefHamza, ref MatchControl);
方法2b:
// same as above just objects are sent without ref
// ...
find.Execute(FindText, MatchCase, MatchWholeWord, MatchWildcards, MatchSoundsLike,
MatchAllWordForms, Forward, Wrap, Format, ReplaceWith, Replace,
MatchKashida, MatchDiacritics, MatchAlefHamza, MatchControl);
方法三:
range.Find.Execute(textToFind, false, false, useWildCards, false, false, true,
msWord.WdFindWrap.wdFindContinue, true, textToReplace, msWord.WdReplace.wdReplaceAll,
false, false, false, false);
【问题讨论】:
-
方法3似乎是最简单的。您可以通过显式声明来避免传递不需要的参数,如here 所示
-
@YosefBernal - 谢谢。你认为最简单和正确吗?尽管在 Microsoft documentation 上看起来像 Method 2 正在被使用。
-
如果能完成工作,这个方法是正确的,对吧?你应该使用你最清楚的东西。想想 6 个月后你看代码时是否能理解代码。您经常会发现 Microsoft 文档并不总是显示最简洁或最常用的语法。我认为对于所有 Office 互操作文档来说尤其如此。
-
我的问题是从 "我面临一个问题..." 开始的 - 现在我找到了问题,它与 find 语法无关,因为所有 3 种方法都可以正常工作。我的问题与UndoRecord 有关,使用
StartCustomRecord和wdReplaceAll肯定存在错误问题。我应该在哪里报告这个错误? [在这里作为答案,还是在其他地方?],-这非常重要。谢谢。
