@is for verbatim string, so that the string is treated as is. Especially useful for paths that have a \which might be treated as escape characters ( like \n)
@用于逐字字符串，以便按原样处理字符串。对于具有\可能被视为转义字符（如\n）的路径特别有用
../..is relative path, in this case, two levels up. ..represents parent of current directory and so on.
../..是相对路径，在这种情况下，向上两级。..代表当前目录的父目录等等。

..is the container directory. So ../..means "up" twice.
For example if your current directory is C:/projects/a/b/cthen ../..will be C:/projects/a
..是容器目录。所以../..意思是“向上”两次。
例如，如果您的当前目录中C:/projects/a/b/c，然后../..将C:/projects/a

new DirectoryInfo(@"../..")means "a directory two levels above the current one".
new DirectoryInfo(@"../..")表示“比当前目录高两级的目录”。
The @denotes a verbatim string literal.
该@表示逐字字符串。

example E:\Software\file\folder
示例 E:\Software\file\folder
/ is the root of the current drive. ./ is the current director. ../ is the parent of the current directory. that is ->E:\ ../.. is relative path, in this case, two levels up. to get folder just write "../../folder"
/ 是当前驱动器的根目录。./ 是现任导演。../ 是当前目录的父目录。即 ->E:\ ../.. 是相对路径，在这种情况下，向上两级。获取文件夹只需写“../../folder”
