writeline所有特殊文件夹 [英] writeline all specialfolders
问题描述
是否可以使用console.writline方法在一个命令中显示Environment.GetFolderPath(Environment.SpecialFolder)的所有位置?
所以我希望它显示AdminTools,ApplicationData,CDBurning等的位置
它可行吗?
< blockquote> 0)命令? c#中没有命令。有声明。方法调用是语句。
1)假设您只想要在一个语句中不想写所有枚举值。好吧,你没必要。
foreach ( var value Enum.GetValues( typeof (Environment.SpecialFolder)))
{
Console.WriteLine( {0}:{1},(Environment.SpecialFolder) value ,Environment.GetFolderPath((Environment.SpecialFolder)值跨度>));
}
好的,这些至少是两个陈述。我将尝试将其合并为一个。

仍然不是单语句版本,但只有一个 Console.WriteLine
call:
StringBuilder sb = new StringBuilder();
foreach ( var value Enum.GetValues( typeof (Environment.SpecialFolder)))
{
sb.Append( String .Format( {0} :{1} \ n,(Environment.SpecialFolder) value ,Environment.GetFolderPath((Environment.SpecialFolder)值跨度>)));
}
Console.WriteLine(sb.ToString());
[Update2]
嗯,仅供记录,这是一个单一陈述的解决方案:
Console.WriteLine(
枚举 .GetValues( typeof (Environment.SpecialFolder))
.Cast< Environment.SpecialFolder>()
。 选择(x => x.ToString())
.Aggregate(
new StringBuilder(),(ag,n)=>
ag.Append( String .Format( {0}:{1} \ n,n,Environment.GetFolderPath((Environment.SpecialFolder)枚举 .Parse( typeof (Environment.SpecialFolder),n, true )) ))
).ToString());
第一个看起来更好:(
is it possible to use a console.writline method to show all of the locations of the Environment.GetFolderPath(Environment.SpecialFolder) in one command?
So i want it to show the location of AdminTools, ApplicationData, CDBurning etc
Is it doable??
0) Command? There is no command in c#. There are statements. Method calls are statements.
1) Let's suppose you mean that you want only don't want to write all enumeration values each in one statements. Well, you don't have to.
foreach (var value in Enum.GetValues(typeof(Environment.SpecialFolder))) { Console.WriteLine("{0}: {1}", (Environment.SpecialFolder)value, Environment.GetFolderPath((Environment.SpecialFolder)value)); }
Ok, these are at least two statements. I will try to make it in one.
[Update]
Still not the one-statement version, but with one singleConsole.WriteLine
call:
StringBuilder sb = new StringBuilder(); foreach (var value in Enum.GetValues(typeof(Environment.SpecialFolder))) { sb.Append(String.Format("{0}: {1}\n", (Environment.SpecialFolder)value, Environment.GetFolderPath((Environment.SpecialFolder)value))); } Console.WriteLine(sb.ToString());
[Update2]
Well, just for the record, here is a one-statement solution:
Console.WriteLine( Enum.GetValues(typeof(Environment.SpecialFolder)) .Cast<Environment.SpecialFolder>() .Select(x => x.ToString()) .Aggregate( new StringBuilder(), (ag, n) => ag.Append(String.Format("{0}: {1}\n",n, Environment.GetFolderPath((Environment.SpecialFolder)Enum.Parse(typeof(Environment.SpecialFolder), n, true)))) ).ToString());
The first one looks better :(
