 //myArray[0..5] 这是切分myArray数组，取的索引为0-5的数据
foreach (var item in myArray[0..5])

 

var myarr = new string[] { "10", "20", "30", "40", "50", "60", "70", "80", "90", "100" }; //提取数组myarr的前3个元素 var reult = myarr[0..3]; //使用linq提取 var result = myarr.Skip(0).Take(3);
--------输出结果：10/20/30--------

 

var myarr = new string[] { "10", "20", "30", "40", "50", "60", "70", "80", "90", "100" }; //提取myarr中倒数第二个元素和倒数第三个元素 var result = myarr[^3..^1]; //使用linq提取 var result = myarr.Skip(myarr.length-3).Take(2);
--------输出结果：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个元素 var result = myarr[4..7]; //使用linq提取 var result = myarr.Skip(4).Take(3);
--------输出结果：50/60/70--------

var myarr = new string[] { "10", "20", "30", "40", "50", "60", "70", "80", "90", "100" }; //提取myarr的最后3个元素 var result = myarr[^3..]; //使用linq提取 var result = myarr.Skip(myarr.length-3);
--------输出结果：80/90/100--------
