要将Collection元素复制到数组,代码如下-
using System; using System.Collections.ObjectModel; public class Demo { public static void Main(){ Collection<string> col = new Collection<string>(); col.Add("One"); col.Add("Two"); col.Add("Three"); col.Add("Four"); col.Add("Five"); col.Add("Six"); col.Add("Seven"); col.Add("Eight"); Console.WriteLine("Collection...."); foreach(string str in col){ Console.WriteLine(str); } string[] strArr = new string[10]; col.CopyTo(strArr, 2); Console.WriteLine("\nArray..."); foreach(string str in strArr){ Console.WriteLine(str); } } }
输出结果
这将产生以下输出-
Collection.... One Two Three Four Five Six Seven Eight Array... One Two Three Four Five Six Seven Eight
现在让我们来看另一个示例-
using System; using System.Collections.ObjectModel; public class Demo { public static void Main(){ Collection<string> col = new Collection<string>(); col.Add("One"); col.Add("Two"); col.Add("Three"); col.Add("Four"); col.Add("Five"); Console.WriteLine("Collection...."); foreach(string str in col){ Console.WriteLine(str); } string[] strArr = new string[10]; col.CopyTo(strArr, 3); Console.WriteLine("\nArray..."); foreach(string str in strArr){ Console.WriteLine(str); } } }
输出结果
这将产生以下输出-
Collection.... One Two Three Four Five Array... One Two Three Four Five
