IEnumerable的应用（即：对于所有数组的遍历，都来自IEnumerable）

所有的数组的遍历，都来自于IEnumerable，所以对IEnumerable的遍历

public static void Print(IEnumerable myList)
{
int i = 0;
foreach (Object obj in myList)
{
if (obj is Student) //这个是类型的判断，这里Student是一个类或结构
{
Student s=(Student)obj;
Console.WriteLine( "t[{0}]:t{1}" , i++, s.Sname);
}
if (obj is int )
{
Console.WriteLine( "INT:{0}" ,obj);
}
}
Console.WriteLine();
}

            if (args == null )
            {
                Console.WriteLine( "args is null" ); // Check for null array
            }
            else
            {
                Console.Write( "args length is " );
                Console.WriteLine(args.Length); // Write array length
                for ( int i = 0; i < args.Length; i++) // Loop through array
                {
                    string argument = args[i];
                    Console.Write( "args index " );
                    Console.Write(i); // Write index
                    Console.Write( " is [" );
                    Console.Write(argument); // Write string
                    Console.WriteLine( "]" );
                }
            }
            Console.ReadLine();

            Console.Write( "请输入：" );
            string contents = Console.ReadLine();
            Console.WriteLine( "刚输入的内容是：" + contents + "——" + cTest.Contents);

            Console.Read();
