5.索引器 数字作为索引号
public class IndexerClass
{
private string[] name = new string[2];
public string this[int index]
{
get
{
if (index < 2)
{
return name[index];
}
return null;
}
set
{
if (index < 2)
{
name[index] = value;
}
}
}
}
public class Test
{
public static void Main(string[] args)
{
IndexerClass ic = new IndexerClass();
ic[0] = "sssssss";
ic[1] = "bbbbbbb";
Console.WriteLine("ic[{0}] 为 {1}",0,ic[0]);
Console.WriteLine("ic[{0}] 为 {1}",1,ic[1]);
Console.ReadKey();
}
}
