我正在将一个项目从 Java 转换为 C#。我试图搜索这个,但我遇到的只是关于枚举的问题。有一个 Hashtable htPlaylist,循环使用 Enumeration 遍历键。我如何将此代码转换为 C#,但使用字典而不是哈希表?
// My C# Dictionary, formerly a Java Hashtable.
Dictionary<int, SongInfo> htPlaylist = MySongs.getSongs();
// Original Java code trying to convert to C# using a Dictionary.
for(Enumeration<Integer> e = htPlaylist.keys(); e.hasMoreElements();
{
// What would nextElement() be in a Dictonary?
SongInfo popularSongs = htPlaylist.get(e.nextElement());
}

呃,只是一个foreach循环?对于给定的
Dictionary<int, SongInfo> htPlaylist = MySongs.getSongs();

任何一个
foreach (var pair in htPlaylist) {
// int key = pair.Key;
// SongInfo info = pair.Value;
...
}
