{
string[] strArr = new string[] { "张某", "张某", "王某", "李某", "张某", "李某", "赵某", "张某" };
Dictionary<string, int> dict = new Dictionary<string, int>();
foreach (string item in strArr)
{
if (dict.ContainsKey(item))
{
dict[item]++;
}
else
{
dict.Add(item, 1);
}
}
foreach (KeyValuePair<string, int> item in dict)
{
Console.WriteLine(string.Format("“{0}”出现里{1}次", item.Key, item.Value));
}
Console.ReadKey();
}
