根據這段代碼，自己編寫了一個小程式作為代碼資料參考，方便以後可以直接拿來用，不需要網上找。如果你覺得還不錯的話，就把它收藏起來吧！
1.前台代碼：
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>數組重複資料刪除值</title> </head> <body> <form id="form1" runat="server"> <div> 數組刪除前： <asp:Label ID="lblResult1" runat="server"></asp:Label> <br /> 數組刪除後： <asp:Label ID="lblResult2" runat="server"></asp:Label> </div> </form> </body> </html>
2.後台代碼：
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_數組_重複資料刪除值 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string strNum = "168,145,150,148,333,888,666,168,144"; //輸出原數組 lblResult1.Text = strNum; string[] arrNum = strNum.Split(','); ArrayList al = new ArrayList(); for (int i = 0; i < arrNum.Length; i++) { //判斷數組值是否已經存在 if (al.Contains(arrNum[i]) == false) { al.Add(arrNum[i]); } } //把ArrayList轉換數組 arrNum = new string[al.Count]; arrNum = (string[])al.ToArray(typeof(string)); //輸出刪除後數組 string result = ""; for (int j = 0; j < arrNum.Length; j++) { if (j != 0) { result += ","; } result += arrNum[j]; } lblResult2.Text = result; } }
3.最終輸出效果：
以上就是關於ASP.NET數組重複資料刪除值的實現方法，希望對大家的學習有所協助。
