从PathTooLongException中检索path信息（寻找path变量）

我在.net 4.0中使用DirectoryInfo和FileInfo来枚举目录树中的文件，我打到PathTooLongException。 简体版如下

public static class Test { public static void Search(DirectoryInfo base) { foreach(var file in base.GetFiles()) { try { Console.WriteLine(file.FullName); } catch(PathTooLongException ex) { // What path was this? } } foreach(var dir in base.GetDirectories()) { Search(dir); } } }

当错误被抛出时，我想知道什么文件path导致了这个问题。 显然，我不能要求FullName因为这是错误的。 我可以从file.Name得到名称，但是如果我不能得到path的其余部分作为file.Directory给出了一个PathTooLongException即使DirectoryInfo文件被发现工作正常！ （我不能使用，但实际的代码要复杂得多）。

通过堆栈跟踪来看，它似乎是使用一个内部path（我看到一个受保护的file.FullPath从debugging），并试图从完整（超大）的path撕裂的目录。 大部分的问题似乎涉及到System.IO.Path.normalizePath ，我听说在.Net 4.0中经历了一些改变。 我还没有尝试过以前的版本的框架。

我的问题：

是否有任何技巧来计算文本文件中的行数？

启动一个执行委托的新进程

在Linux上运行ASP Classic和.NET

DataGridView不填充

input语言挂钩

我怎样才能从这个例外中得到完整的path; 似乎没有任何有用的信息通过。

为什么框架需要限制path中的字符来切断文件名？

提前感谢您的帮助，

除了使用反射，或者使用库或P / Invoke来使用支持长路径的Windows API并手动检查长度之外，我无法想象其他任何方式。 完整路径存储在名为FullPath的protected string字段中

foreach(var dir in new DirectoryInfo (@"D:longpaths") .GetFileSystemInfos("*.*",SearchOption.AllDirectories)) { try { Console.WriteLine(dir.FullName); } catch (PathTooLongException) { FieldInfo fld = typeof(FileSystemInfo).GetField( "FullPath",BindingFlags.Instance | BindingFlags.NonPublic); Console.WriteLine(fld.GetValue(dir)); // outputs your long path } }

如果你试图用文件做一些事情，而不是仅仅检查文件的长度，那么我会建议你使用像BCL团队这样的一个库，但是它不会创建DirectoryInfos ， FileInfo或者FileSystemInfo ，只有字符串。 所以它可能不是你的代码似乎替代你的代码。

至于你的第二个问题的答案，我建议阅读这篇博客文章处理.NET中的长路径。 这是一个引用，解释了为什么他们没有很快在.NET中添加长路径支持。

很少有人抱怨32K的限制，所以问题解决了？ 不完全的。 有几个原因，我们不愿意在过去添加长路径，为什么我们仍然很小心，涉及安全性， API语法中的不一致的支持，以及应用程序的兼容性。

这是一个由3部分组成的系列文章，解释了为什么API是这样的以及为什么限制在那里的一些原因。

解决方法：

[root@bogon secrets]# hostname
bogon

解决方法：

1 执行hostname命令

    可以看出 ping 不通我们的hostname 这就是原因所在

2 修改 /etc/sysconfig/network

     改成我们的hostname命令下的名字

3 修改   /etc/hosts内容

    加上我们的hostname命令下的名字

4 最后执行 /etc/rc.d/init.d/network rest
