Add array List C#

แบบกำหนดขนาด Array

int[] AList = new int[400];for (int i= 0; i< 400; i++){     AList[i] = value[i];}

แบบไม่กำหนดขนาด Array

using System.Collections.Generic; List<int> AList = new List<int>();for (int i= 0; i< 10; i++){     AList.Add(value[i]);}

แปลงกับไปเก็บไว้ในอีก Array 

int[] terms = termsList.ToArray();

อีกรูปแบบ 

Variable   add system.collections

ArrayList arrDuplicate = new ArrayList();

if (!arrDuplicate.Contains(strDuplicate)) {      arrDuplicate.Add(strDuplicate); }

Output

foreach (Object obj in arrDuplicate) {     // }

Sort

arrDuplicate.Sort();

Muti Array List

Set New Class

public class CheckMaterialImport {   public string Layer { get; set; }   public string Matcode { get; set; } }

Set Variable

var MatCodeList = new List<CheckMaterialImport>();

Add Values

MatCodeList.Add(new CheckMaterialImport       {          Layer = drRL["LayerNo"].ToString(),          Matcode = MateCode       });

Display

foreach (var item in MatCodeList) {    string Layer_ = item.Layer;    string Matcode_ = item.Matcode; }
