 //myArray[0..5] 這是切分myArray數組，取的索引為0-5的數據
foreach (var item in myArray[0..5])

 

var myarr = new string[] { "10", "20", "30", "40", "50", "60", "70", "80", "90", "100" }; //提取數組myarr的前3個元素 var reult = myarr[0..3]; //使用linq提取 var result = myarr.Skip(0).Take(3);
--------輸出結果：10/20/30--------

 

var myarr = new string[] { "10", "20", "30", "40", "50", "60", "70", "80", "90", "100" }; //提取myarr中倒數第二個元素和倒數第三個元素 var result = myarr[^3..^1]; //使用linq提取 var result = myarr.Skip(myarr.length-3).Take(2);
--------輸出結果：80/90--------

var myarr = new string[] { "10", "20", "30", "40", "50", "60", "70", "80", "90", "100" }; //提取myarr中索引index=4、5、6的3個元素 var result = myarr[4..7]; //使用linq提取 var result = myarr.Skip(4).Take(3);
--------輸出結果：50/60/70--------
