foreach (string f in Directory.GetFiles(d, txtFile.Text))

DirSearch(d);
catch (System.Exception excpt)
Console.WriteLine(excpt.Message);
这里也是应用打开的截图：

我要添加一个保存按钮，点击后会保存到特定位置，我该怎么做。
【问题讨论】：
【参考方案1】：如果我理解正确，请使用简单的 I/O 操作。
using(StreamWriter writer = new StreamWriter("debug.txt", true))
foreach (string item in lstFilesFound.Items)
writer.WriteLine(item.ToString());
一些额外的指针：
在 DirSearch 中，为 Directory.GetDirectories(sDir) 创建一个变量。您当前的代码导致这个东西在每个循环中都进行计算。在其他领域寻找一些更相似的重构代码。
var dirs = Directory.GetDirectories(sDir);
foreach (string d in dirs)
var files = Directory.GetFiles(d, txtFile.Text);
foreach (string f in files)
lstFilesFound.Items.Add(f);
DirSearch(d);
希望对你有帮助。
【讨论】：
我相信他的意思是 foreach 行（Directory.GetDirectories(sDir) 中的字符串 d）。如果这是正确的，我认为它没有区别，GetDirectories 不会为每个循环迭代执行 @BenSchwehn：我编辑了我的帖子以反映我所指的内容。我觉得它应该有所作为。请发表您的意见。谢谢 应该没什么区别。参见例如***.com/questions/3763933/… 太棒了...我在考虑for 循环，它应该有所作为（如果用于计算计数）。感谢您的澄清。很有帮助，肯定会在我的代码中节省几行......:)
好的，我明白你关于循环的意思，它有相同的文件显示超过 200 次，我将如何删除这个循环，我只想要每个文件中的一个供参考【参考方案2】：
我假设它是您想要保存到文本文件的已找到文件的列表，在您的保存事件中如何处理（粗略的代码，因此未经广泛测试）？
using (FileStream fs = new FileStream("c:\\files.txt", FileMode.Create, FileAccess.Write))
using (StreamWriter sw = new StreamWriter(fs))
foreach (string item in lstFilesFound.Items)
sw.WriteLine(item);
