推荐答案

看看System.IO命名空间中的DirectoryInfo类，它是C#代码，但易于转换！

Have a look at the DirectoryInfo class in the System.IO namespace, C# code but simple to convert!

string directoryPath = @"C:\FolderToSearch";
DirectoryInfo dir = new DirectoryInfo(directoryPath);
FileInfo[] files = dir.GetFiles("*.csv", SearchOption.AllDirectories);

foreach (FileInfo file in files)
{
    // However you want to process the CSV file
}

看看:

Take a look at: DirectoryInfo.GetFiles method[^] - with an example in VB.NET.
