数组去重
string[] x = { "aaa", "bbb", "aaa", "ccc", "bbb", "ddd", "ccc", "aaa", "bbb", "ddd" }; List<string> y = new List<string>(); foreach (string z in x) { if (!y.Contains(z)) y.Add(z); } foreach (string z in y) { Console.WriteLine(z); } Console.ReadLine();
冒泡排序
int[] z =new int[]{2,3,1,5,4}; for(int i = 0;i<i.Lengt-1;i++){ for(int j = i+1;j<i.Length;j++){ if(z[i]>z[j]){ int f=a[i]; a[i]=a[j]; a[j]=f } } } for(int i=0;i<a.Length;i++){ Console.WriteLine(a[i]); }
