Converting Enumeration<Integer> for loop from Java to C#? What exactly is an Enumeration<Integer> in C#?
本问题已经有最佳答案,请猛点这里访问。
我正在把一个项目从Java转换成C语言。我试过搜索这个,但我遇到的只是关于枚举的问题。有一个哈希表htplaylist,循环使用枚举遍历键。如何将此代码转换为C,但使用字典而不是哈希表?
1 2 3 4 5 6 7 8 9 | // 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()); } |
嗯,只是一个
1 | Dictionary<int, SongInfo> htPlaylist = MySongs.getSongs(); |
任何一个
1 2 3 4 5 | foreach (var pair in htPlaylist) { // int key = pair.Key; // SongInfo info = pair.Value; ... } |
或者如果你只想要钥匙:
1 2 3 | foreach (int key in htPlaylist.Keys) { ... } |
