如何比较字符串数组？

viphk 2010-11-12 11:22:05

有这么一个数组：

string Txt = Convert.ToString(row["txt"]);

string hmRemove = Txt.TrimEnd('|');

String[] strTemp = hmRemove.Split('|');

然后是这么几个整数：
12
35
65
89
56
80

怎么判断这个数组中是否存在上面数字中任一三个数？
只要满足存在上面整数中的任一三个数就返回真，

C# code

//加上Distinct 更好一点
void Main()

string[] nums = {"12","35","65","89","56","80"};

string[] nums1 = {"12","35","65","891","561","801"};

string[] nums2 = {"12","35","651","891","……

这样比较效力是不是要高？

哦，这么写是错的，没看清楚。

Int32 containsCount = 0;

String[] nums = new String(){"12","35","65","89","56","80"};



foreach(String num in nums)

{

    if(Array.IndexOf(strTemp,num)>-1) containsCount++;

    return containsCount >=3;

}

这么写吗？

string Txt = Convert.ToString(row["txt"]);

Console.WriteLine(RegEx.IsMath(txt,@"(^|\|)(12|35|65|89|56|80)($|\|)"));

我喜欢用正侧

除了一个一个判断最后判断>3还有啥办法吗？

你可以把containsCount 的值放foreach里面，这样可以省点时间
