C#：如何从一个文件夹中打开多个word文档

Question

我有一个文件夹，其中包含名为 Test1、Test2 和 Test3 的三个 word 文档，所有文档都具有 docx 扩展名。

我知道如果我们想手动打开一个文件，我们可以指定一个文件路径并使用下面的代码：

Word.Application fileOpen = new Word.Application();
Word.Document document = fileOpen.Documents.Open(filePath);

但是，有没有其他方法可以 select 该文件夹，但一次打开一个文件？我想做以下事情：

打开 Test1.docx -> 进行一些更改 -> 保存 -> 关闭
打开Test2.docx -> 重复上面的操作，最后对Test3.docx

我到处搜索，但找不到与此相关的内容。如有任何帮助，我们将不胜感激。

Answer 1

对于这种情况，我们假设您已经知道要打开哪个文件夹并从中读取文件。

首先，您必须导入 System.IO

using System.IO;

在该命名空间内，Directory.GetFiles() 将为您提供字符串数组中的文件名。

private static void FolderReader()
{
    string folderPath = @"C:\someFolder\";
    Word.Application fileOpen = new Word.Application();
    string[] filePaths = Directory.GetFiles(folderPath);

    foreach (string filePath in filePaths)
    {
        Word.Document document = fileOpen.Documents.Open(filePath);
        // perform continue with your algorithm...
        // close the file when you're done.
    }
}

希望这足以让您入门。祝你好运。

我找到了问题的答案。我在下面包含了示例代码和解释。

您必须为此使用以下内容！

Using System.IO;

对于此示例，我们将着眼于从桌面目录中获取所有 "doc" 和 "docx" 文件。

//Directory to search through:
string sampleFilePath = @"C:\Users\YourUsername\Desktop";

//Now we create a list to hold all the filepaths that exist in this directory
List<string> allFilePaths = new List<string>();
//Extract all doc/docx files on Desktop
string[] start = Directory.GetFiles(sampleFilePath, "*doc");
        for (int begin = 0; begin < start.Length; begin++)
        {
            allFilePaths.Add(start[begin]);
        }

//The above code does not extract doc/docx files that are contained inside folders that exist on desktop.
//So we need to get those filepaths separately.
string[] filePaths = Directory.GetDirectories(sampleFilePath);
        for (int i = 0; i < filePaths.Length; i++)
        {
            //Any doc and docx files found in the subdirectories are added to the list
            string[] files = Directory.GetFiles(filePaths[i], "*doc");
            for (int j = 0; j < files.Length; j++)
            {
                allFilePaths.Add(files[j]);
            }
            //Continue checking the subdirectories for more folders until you reach the end, then move on to the second subdirectory from the very beginning.
            string[] checkMoreDirectories = Directory.GetDirectories(filePaths[i]);
            checkForMoreDirectories(checkMoreDirectories, ref allFilePaths);
        }

checkForMoreDirectories 方法如下。

static void checkForMoreDirectories (string[] checkMoreDirectories, ref List<string> myList)
    {
        //This function calls itself recursively for every subdirectory within the previous subdirectory until it reaches the end where there are no more folders left
        //Continuously add any doc/docx files found before going deeper into the subdirectory
        for (int i = 0; i < checkMoreDirectories.Length; i++)
        {
            string[] files = Directory.GetFiles(checkMoreDirectories[i]);
            for (int j = 0; j < files.Length; j++)
            {
                myList.Add(files[j]);
            }
            string[] temp = Directory.GetDirectories(checkMoreDirectories[i]);
            //Recursive call
            checkForMoreDirectories(temp, ref myList);
        }
    }

现在，即使您有 1000 个文件夹，每个文件夹都有许多存储 doc/docx 个文件的子文件夹，您的列表中也会有每个文件夹的文件路径。然后您可以访问此列表并通过使用 Microsoft Word Interops 打开每个文件并进行更改等。
