在C#中,比较两个数组的不同值.输出出来对于日常.NET编程比较实用

static void Main(string[] args)
{
String strName = "";
Dictionary<int, int> map = new Dictionary<int, int>();
int[] ch2 = { 2, 32, 33, 44, 12 };
for (int i = 0; i < ch2.Length; ++i)
{
map.Add(ch2[i], 0);
}
int[] ch1 = { 1, 2, 3, 4, 5, 6, 7, 8 };

for (int i = 0; i < ch1.Length; ++i)
{
if (!map.ContainsKey(ch1[i]))
{
strName += ch1[i].ToString() + ",";
}
}

Console.WriteLine("不在ch2中：{0}", strName);
Console.ReadLine();
}
