在实际项目中,C#字典(Dictionary)可以应用于多种场景。以下是一些常见的应用案例:
Dictionary<string, string> config = new Dictionary<string, string>(); config["server"] = "localhost"; config["port"] = "8080"; Dictionary<int, User> userCache = new Dictionary<int, User>(); userCache[1] = new User { Id = 1, Name = "Alice" }; userCache[2] = new User { Id = 2, Name = "Bob" }; Dictionary<string, int> wordCount = new Dictionary<string, int>(); wordCount["apple"] = 3; wordCount["banana"] = 5; Dictionary<State, State> stateTransitions = new Dictionary<State, State>(); stateTransitions[State.Initial] = State.Running; stateTransitions[State.Running] = State.Paused; stateTransitions[State.Paused] = State.Stopped; Dictionary<string, string> translations = new Dictionary<string, string>(); translations["hello"] = "你好"; translations["world"] = "世界"; Dictionary<string, Color> colorMap = new Dictionary<string, Color>(); colorMap["red"] = Color.FromArgb(255, 0, 0); colorMap["green"] = Color.FromArgb(0, 255, 0); colorMap["blue"] = Color.FromArgb(0, 0, 255); 这些只是字典在实际项目中的一些应用案例,实际上,字典可以根据需求应用于各种场景。
