如何逃避包含空格的路径 [英] How to escape path containing spaces
问题描述
myapp.exe --path C:\Program Files\MyApp`
成为
new string [] {--path,C:\Program,Files\MyApp}
但是
myapp.exe --pathC:\Program Files\MyApp
成为
new string [] {--path,C:\Program Files\MyApp}
,它的工作正常,你可以很容易地解析。
我想扩展一组添加的参数,并开始一个新的过程结果一组参数:
new ProcessStartInfo(
Assembly.GetEntryAssembly()。位置,
String.Join(,Enumerable.Concat(args,new [] {--flag})))
这将成为 myapp.exe --path C:\Program File s\MyApp --flag
哪里路径丢弃它的转义。
如何解决它与常见的解决方案? (没有搜索每个参数的值需要转义和手动引用)
我不认为这是可能的,因为空间是用于CLI参数的分隔符,以便它们需要转义。
您可以非常好地将其解压缩到扩展方法中,以便您可以运行 args 。
public static string [] Escape(this string [ ] args)
{
return args.Select(s => s.Contains()?string.Format(\{0} \,s):s) .ToArray();
}
To pass a path with spaces to .NET console application you should escape it. Probably not escape but surround with double quotes:
myapp.exe --path C:\Program Files\MyApp`
becomes
new string[] { "--path", "C:\Program", "Files\MyApp" }
but
myapp.exe --path "C:\Program Files\MyApp"
becomes
new string[] { "--path", "C:\Program Files\MyApp" }
and it works fine and you can parse that easily.
I want to extend the set of parameters given with an addition one and start a new process with the resulting set of parameters:
new ProcessStartInfo(
Assembly.GetEntryAssembly().Location,
String.Join(" ", Enumerable.Concat(args, new[] { "--flag" })))
This becomes myapp.exe --path C:\Program Files\MyApp --flag
where path drops its escaping.
How to workaround it with common solution? (without searching each parameter's value requiring escaping and quoting it manually)
I don't think it is possible since the space is the delimiter for CLI arguments so they would need to be escaped.
You could extract this into an extension method quite nicely so you can just run args.Escape()
in your code above.
public static string[] Escape(this string[] args)
{
return args.Select(s => s.Contains(" ") ? string.Format("\"{0}\"", s) : s).ToArray();
}
