推荐答案

您在List< t>中有Revesre和ToArray方法，这是什么问题?

请参阅: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx [^ ]

要查看如何使用反射器实现该功能，请在Visual Studio中启用.net源调试，或为其源代码启用google.

You have Revesre and ToArray methods in List<t>, what''s the problem?

See: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx[^]

To see how it is implemented use reflector, enable .net source debugging in visual studio, or google for it''s source code.

List<string> dinosaurs = new List<string>();

dinosaurs.Add("Pachycephalosaurus");
dinosaurs.Add("Parasauralophus");
dinosaurs.Add("Mamenchisaurus");
dinosaurs.Add("Amargasaurus");
dinosaurs.Add("Coelophysis");
dinosaurs.Add("Oviraptor");

string[] input = dinosaurs.Reverse().ToArray();

List<string> list = new List<string>();
list.Add("C++");
list.Add("C#");
list.Add("Java");
list.Add("Objective-C");

list.Reverse();
string[] array = list.ToArray();
for (int i = 0; i < array.Length; i++)
{
    Console.WriteLine(array[i]);
}
