获取或设置StringDictionary中指定键关联的值,代码如下 −
示例
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
StringDictionary strDict = new StringDictionary ();
strDict.Add("A", "Books");
strDict.Add("B", "Electronics");
strDict.Add("C", "Appliances");
strDict.Add("D", "Pet Supplies");
strDict.Add("E", "Clothing");
strDict.Add("F", "Footwear");
Console.WriteLine("Value associated with key D = "+strDict["D"]);
Console.WriteLine("Value associated with key F = "+strDict["F"]);
}
}
输出
这将产生以下输出 −
Value associated with key D = Pet Supplies Value associated with key F = Footwear
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 strDict = new StringDictionary ();
strDict.Add("A", "Books");
strDict.Add("B", "Electronics");
strDict.Add("C", "Appliances");
strDict.Add("D", "Pet Supplies");
strDict.Add("E", "Clothing");
strDict.Add("F", "Footwear");
Console.WriteLine("Value associated with key D = "+strDict["D"]);
Console.WriteLine("Value associated with key F = "+strDict["F"]);
strDict["F"] = "HDD";
Console.WriteLine("Value associated with key F (UPDATED) = "+strDict["F"]);
}
}
输出
这将产生以下输出 −
Value associated with key D = Pet Supplies Value associated with key F = Footwear Value associated with key F (UPDATED) = HDD
