要运行 PowerShell 脚本,使用运行 PowerShell 脚本操作并为要执行的转换填充适当的命令。 例如,以下 PowerShell 脚本将存储在BinaryNumber变量中的二进制数转换为十进制数。 此操作生成PowershellOutput变量,该变量将转换结果存储为文本。 备注 您可以在本文中找到有关 PowerShell 转换方法的更多信息。
PSSerializeJSONLongEnumAsNumber 這項功能使 CmdletConvertTo-Json能夠根據Int64/long或UInt64/ulong,將任何列舉值序列化為數值,而非該列舉值的字串表示。 這使列舉序列化的行為與其他列舉基底類型一致,其中 Cmdlet 將列舉序列化為其數值形式。 使用EnumsAsStrings參數進行序列化為字串表示法。
PSSerializeJSONLongEnumAsNumber-ConvertTo-Json現在會將大型列舉視為數位 (#20999) (感謝@jborean93!) 效能改善 PowerShell 7.5-rc.1 包含來自的 @jborean93,這提高了物件數組在進行+=作業時的效能。 下列範例測量將元素新增至陣列的不同方法的效能。
