主题:yield问题
using System;
using System.Collections;
public class List
{
public static IEnumerable Power(int number, int exponent)
{
int counter = 0;
int result = 1;
while (counter++ < exponent)
{
result = result * number;
yield return result;
}
}
static void Main()
{
// Display powers of 2 up to the exponent 8:
foreach (int i in Power(2, 8))
{
Console.Write("{0} ", i);
}
}
}
这个代码在我机子上运行出错了,编译提示yield return result;中的return后要加;,我的VS版本是2003,请问是怎么回事
