Recursively walking through a directory tree and listing file names
提问by Steve Way
I'm trying to walk through a whole directory tree and print out all the file names on a listbox control. I wrote some code but there are errors. Not sure what I'm doing wrong. By the way, this is in C# using WPF in Visual Studio.
我试图遍历整个目录树并打印出列表框控件上的所有文件名。我写了一些代码，但有错误。不知道我做错了什么。顺便说一下，这是在 C# 中使用 Visual Studio 中的 WPF。

如果您不想下载项目解决方案，这里是 MainWindow.xaml.cs 中的代码：http: //pastebin.com/cWRTeq3N
I'll paste the code here as well.
我也会在这里粘贴代码。
public partial class MainWindow : Window
{
private void Button_Click_1(object sender, RoutedEventArgs e)
{
string sourcePath = @"C:\temp\";
static void DirSearch(string sourcePath)
{
try
{
foreach (string d in Directory.GetDirectories(sourcePath))
{
foreach (string f in Directory.GetFiles(d))
{
listBox1.Items.Add(f);
}
DirSearch(d);
}
}
catch (Exception ex)
{
listBox1.Items.Add(ex.Message);
}
}
}
}

There is a complete exampleon the Microsoft support site
Microsoft 支持站点上有一个完整的示例
The issue here is that you want to callDirSearchfrom the event handler, but it appears you're trying to definethe method DirSearchinside the event handler. This is not valid.
这里的问题是您想从事件处理程序调用DirSearch，但似乎您正在尝试在事件处理程序中定义方法DirSearch。这是无效的。
You need to change your code as follows:
您需要按如下方式更改代码：
private void Button_Click_1(object sender, RoutedEventArgs e)
{
string sourcePath = @"C:\temp\";
this.DirSearch(sourcePath);
}
private void DirSearch(string sDir)
{
try
{
foreach (string f in Directory.GetFiles(sDir, txtFile.Text))
{
lstFilesFound.Items.Add(f);
}
foreach (string d in Directory.GetDirectories(sDir))
{
this.DirSearch(d);
}
}
catch (System.Exception excpt)
{
listBox1.Items.Add(ex.Message);
}
}

Use GetDirectories() overload accepting SearchOption:
使用接受 SearchOption 的 GetDirectories() 重载：
string[] dirs = Directory.GetDirectories(path, "*", SearchOption.AllDirectories))
foreach(dir)
{
...
}
or better EnumerateFiles():
或更好的EnumerateFiles()：
IEnumerable<string> files = Directory.EnumerateFiles(path, "*.*", SearchOption.AllDirectories))
foreach(files)
{
...
}
Notice it performs lazyfilesystem scan.
请注意，它执行延迟文件系统扫描。
