C#中获取或设置StringDictionary中指定键处的值

要获取或设置StringDictionary中指定键的值，代码如下-

示例

using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringDictionary myDict = new StringDictionary(); myDict.Add("1", "Tablet"); myDict.Add("2", "Desktop"); myDict.Add("3", "Speakers"); myDict.Add("4", "Laptop"); myDict.Add("5", "Notebook"); myDict.Add("6", "Ultrabook"); myDict.Add("7", "HDD"); myDict.Add("8", "SDD"); myDict.Add("9", "Headphone"); myDict.Add("10", "Earphone"); Console.WriteLine("Value for key 5 = "+myDict["5"]); } }

输出结果

这将产生以下输出-

Value for key 5 = Notebook

示例

让我们看另一个例子-

using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringDictionary myDict = new StringDictionary(); myDict.Add("1", "Tablet"); myDict.Add("2", "Desktop"); myDict.Add("3", "Speakers"); myDict.Add("4", "Laptop"); myDict.Add("5", "Notebook"); myDict.Add("6", "Ultrabook"); myDict.Add("7", "HDD"); myDict.Add("8", "SDD"); myDict.Add("9", "Headphone"); myDict.Add("10", "Earphone"); Console.WriteLine("Value for key 5 = "+myDict["5"]); myDict["5"] = "Flash Drive"; Console.WriteLine("Value for key 5 [Updated] = "+myDict["5"]); } }

输出结果

这将产生以下输出-

Value for key 5 = Notebook Value for key 5 [Updated] = Flash Drive
