scala在case类之间转换的最佳方法是什么？(What would be the best way in scala to convert between case classes?)

 为了获得Steam游戏文件夹，您必须按照以下步骤操作： 
 
 
 
 找到Steam安装文件夹 
 
 
 选中Steam acf文件和libraryfolders.vdf 
 
 
 您可以在Windows注册表中找到Steam InstallPath ： 
 
 
 
 32位： HKEY_LOCAL_MACHINE\SOFTWARE\Valve\Steam 
 
 
 64位： HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Valve\Steam 
 
 
 您可以使用以下代码从注册表项中读取值 ： 
 
Dim strSteamInstallPath as String = My.Computer.Registry.GetValue(
    "HKEY_LOCAL_MACHINE\SOFTWARE\Valve\Steam", "InstallPath", Nothing)

MsgBox("The install path is " & strSteamInstallPath)
 
 一旦你有Steam主文件夹（包含steam.exe文件夹），你可以从\steamapps子文件夹中包含的appmanifest_<steamappid>.acf文件中读取游戏安装文件夹。 
 
 例如， appmanifest_2280.acf包含有关Ultimate Doom信息。 
 
 您可以搜索特定的steamappid或分析每个文件并从name密钥中获取游戏名称。 
 
 另请查看\steamapps子文件夹中的libraryfolders.vdf以获取其他游戏安装文件夹。 
 
 例如，我在D:\mygames有一些游戏，所以我的libraryfolders.vdf是： 
 
"LibraryFolders"
{
    "TimeNextStatsReport"   "xxxxxxxxxxx"
    "ContentStatsID"        "xxxxxxxxxxx"
    "1"                     "D:\\mygames"
}
 
 一旦你有这个替代文件夹，检查包含在\steamapps子文件夹中的acm文件。 

In order to obtain a Steam games folder you have to follow this steps:
 
 
 
find Steam installation folder
 
 
check Steam acf files and libraryfolders.vdf
 
 
You can find Steam InstallPath in windows registry:
 
 
 
32-bit: HKEY_LOCAL_MACHINE\SOFTWARE\Valve\Steam
 
 
64-bit: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Valve\Steam
 
 
You can read a Value from a Registry Key using this code:
 
Dim strSteamInstallPath as String = My.Computer.Registry.GetValue(
    "HKEY_LOCAL_MACHINE\SOFTWARE\Valve\Steam", "InstallPath", Nothing)

MsgBox("The install path is " & strSteamInstallPath)
 
Once you have Steam main folder (the one containing steam.exe) you can read games installation folder from appmanifest_<steamappid>.acf files contained in \steamapps subfolder.
 
For example, appmanifest_2280.acf contains informations about Ultimate Doom.
 
You can search for a particular steamappid or analyze every files and get game name from name key.
 
Also check libraryfolders.vdf in \steamapps subfolder for other game installation folders.
 
For example I have some games in D:\mygames so my libraryfolders.vdf is:
 
"LibraryFolders"
{
    "TimeNextStatsReport"   "xxxxxxxxxxx"
    "ContentStatsID"        "xxxxxxxxxxx"
    "1"                     "D:\\mygames"
}
 
Once you have this alternative folder, check for acm files contained in \steamapps subfolder.
