要获取或设置与ListDictionary中的指定键关联的值,代码如下-
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main() { ListDictionary dict = new ListDictionary(); dict.Add("A", "Books"); dict.Add("B", "Electronics"); dict.Add("C", "Appliances"); dict.Add("D", "Pet Supplies"); dict.Add("E", "Clothing"); dict.Add("F", "Footwear"); Console.WriteLine("Value associated with key C = "+dict["C"]); } }
输出结果
这将产生以下输出-
Value associated with key C = Appliances
让我们看另一个例子-
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main() { ListDictionary dict = new ListDictionary(); dict.Add("A", "Books"); dict.Add("B", "Electronics"); dict.Add("C", "Appliances"); dict.Add("D", "Pet Supplies"); dict.Add("E", "Clothing"); dict.Add("F", "Footwear"); Console.WriteLine("Value associated with key C = "+dict["C"]); dict["C"] = "HDD"; Console.WriteLine("Value associated with key C [Updated] = "+dict["C"]); } }
输出结果
这将产生以下输出-
Value associated with key C = Appliances Value associated with key C [Updated] = HDD
