Answer 1

来自 Powershell Scripting :

According to the variable syntax, if the path to a file is enclosed in braces preceded by a dollar sign (as in ${C:\foo.txt}), it refers to the contents of the file. If it is used as an L-value, anything assigned to it will be written to the file. When used as an R-value, it will be read from the file. If an object is assigned, it is serialized before storing it.
