C#中如何随机取字符串中的文字

 String[] present =String[ "红酒两瓶", "马克杯一个", "磐基礼卡100", "磐基礼卡500", "GUCCI包", "BURBERRY香水", "梵思诺毛巾", "OMEGA手表", "万宝龙背包", "施瓦洛斯奇水晶项链" ];    这是我定义的字符串数组   怎样取得其中的任意一项

Answer 1

C#中数组不是这样建的

String[] present =new String[]{ "红酒两瓶", "马克杯一个", "磐基礼卡100", "磐基礼卡500", "GUCCI包", "BURBERRY香水", "梵思诺毛巾", "OMEGA手表", "万宝龙背包", "施瓦洛斯奇水晶项链" };

取出可以使用随机数类Random r = new Random();

完整代码
String[] present =new String[]{ "红酒两瓶", "马克杯一个", "磐基礼卡100", "磐基礼卡500", "GUCCI包", "BURBERRY香水", "梵思诺毛巾", "OMEGA手表", "万宝龙背包", "施瓦洛斯奇水晶项链" };
Random r = new Random();
string str = present[r.Next(0,present.Length-1)];
