C#如何在word文件中搜索给定的单词

Question

如何检查单词文件是否包含给定的单词？

示例：我想写一个函数：bool IsContain(string word, string filePath)。如果 filePath 包含 word，该函数将 return 为真。否则会 return false.

这是我使用 Aspose 框架的解决方案。有没有更好的解决方案？

public class FindContentOfWordDoc
{
    public bool FindContent(string filePath, string content)
    {
        var doc = new Document(filePath);

        var findReplaceOptions = new FindReplaceOptions
        {
            ReplacingCallback = new FindCallBack(),
            Direction = FindReplaceDirection.Backward
        };

        var regex = new Regex(content, RegexOptions.IgnoreCase);
        doc.Range.Replace(regex, "", findReplaceOptions);

        return (findReplaceOptions.ReplacingCallback as FindCallBack)?.IsMatch ?? false;
    }

    private class FindCallBack : IReplacingCallback
    {
        public bool IsMatch { get; private set; }
        ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
        {
            IsMatch = true;
            return ReplaceAction.Stop;
        }
    }
}

谢谢！

Answer 1

如果您正在使用评论中所述的 Aspose 库，您可以通过自定义实现 IReplacingCallback 接口来实现。

bool IsContain(string word, string filePath)
{
    Document doc = new Document(filePath);

    OccurrencesCounter counter = new OccurrencesCounter();

    doc.Range.Replace(new Regex(word), counter, false);

    return counter.Occurrences > 0;

}


private class OccurrencesCounter : IReplacingCallback
{
    public ReplaceAction Replacing(ReplacingArgs args)
    {
        mOccurrences++;

        return ReplaceAction.Skip;
    }


    public int Occurrences
    {
        get { return mOccurrences; }
    }

    private int mOccurrences;

}

使用 VSTO 执行代码段：

if (Application.Selection.Find.Execute(ref findText,
ref missing, ref missing, ref missing, ref missing, ref missing, ref 
missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref 
missing, 
ref missing, ref missing)) 
{ 
   MessageBox.Show("Text found.");
} 
else
{ 
   MessageBox.Show("The text could not be located.");
}
