这将为您提供帮助.

Will this help you.

private void Form1_Load(object sender, EventArgs e)
{
    string[] files = Directory.GetFiles("DirectoryPath");

    for (int i = 0; i < files.Length; i++)
    {
        comboBox1.Items.Add(files[i]);
    }
}

另外，如果只想显示文件名，则可以使用Path.GetFileName(files [i]);.或Path.GetFileNameWithoutExtension(files [i]);静态Path类中的方法.

注意:万一您不知道可以通过双击表单轻松地生成Form_Load事件处理程序.

如果您还想从子目录(文件夹中的文件夹)中获取文件，则可以执行以下操作:

Directory.GetFiles("DirectoryPath"，"*.*"，SearchOption.AllDirectories);
"*.*"是搜索模式，因此，如果只需要文本文件，则可以将其更改为"* .txt"

also if you want to display just the file name you could use Path.GetFileName(files[i]); or Path.GetFileNameWithoutExtension(files[i]); methods from the static Path class.

Note: Just in case you don''t know you can easily generate a Form_Load event handler by double clicking on your form.

And if you want to get files from sub directories (folders within folders) as well you would do something like this:

Directory.GetFiles("DirectoryPath", "*.*", SearchOption.AllDirectories);
the "*.*" is the search pattern so if you only wanted text files you could change it to "*.txt"

您必须以Load()形式编写代码.
第一个

You have to write the code in your form Load().
First

string[] filePaths = Directory.GetFiles(@"c:\dir");
fot (int i = 0; i < filePaths.Length; ++i) {
    string path = filePaths[i];
    Console.WriteLine(System.IO.Path.GetFileName(path));
}

在此for循环中，检查每个文件扩展名以做

Inside this for loop check each files extension to do it

Use Path.GetExtension(string path)

如果是.txt，则将其添加到您的组合框中...

祝你好运.

if it is .txt then add to your combobox...

Good luck..

好像你想看看^ ]方法.它将目录中的所有文件提取到string[]中.

干杯！

It looks as if you would want to check out the Directory.GetFiles[^] method. It fetches all the files of a directory into a string[].

Cheers!
