The keys and values in a hashtable can have any .NET object type, and a single hashtable can have keys and values of multiple types. 下列語句會建立進程名稱字串和進程物件值的哈希表,並將它儲存在$p變數中。 PowerShell $p= @{"PowerS
0键为Integer。 可以使用任何Hashtable方法来访问存储的值。 PS> 'Good Dog' -match 'Dog' True PS> $Matches[0] Dog PS> $Matches.Item(0) Dog PS> $Matches.0 Dog 命名捕获 默认情况下,捕获按从左到右的数字升序存储。 还可以将名称分配给捕获组。 此名称将成为哈希表自动变量上的$Matches键。
