using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Collections; //引用 public partial class NetObjects_数组_删除重复值 : System.Web.UI.Page { protected void Page_Load( object sender, EventArgs e) { string strNum = "168,145,150,148,333,888,666,168,144" ; //输出原数组 lblResult1.Text = strNum; string [] arrNum = strNum.Split( ',' ); ArrayList al = new ArrayList(); for ( int i = 0; i < arrNum.Length; i++) { //判断数组值是否已经存在 if (al.Contains(arrNum[i]) == false ) { al.Add(arrNum[i]); } } //把ArrayList转换数组 arrNum = new string [al.Count]; arrNum = ( string [])al.ToArray( typeof ( string )); //输出删除后数组 string result = "" ; for ( int j = 0; j < arrNum.Length; j++) { if (j != 0) { result += "," ; } result += arrNum[j]; } lblResult2.Text = result; } } |
3.最终输出效果:
以上就是关于ASP.NET数组删除重复值的实现方法,希望对大家的学习有所帮助。
