Question

我有这个代码可以拆分特定的字符串。

str = "\n\nThis\nString\nis\nsplit\ninto\narray";
string[] delimiterChar = { "\n" };

var splitArray = str.Split(delimiterChar);

split数组是简单的字符串数组，但为什么不能使用以下方法删除前2项：

splitArray[0].remove();
splitArray[0].remove();

Answer 1

如果需要删除空条目，则只需在split方法中指定它。无需手动删除它们。

如果您想要专门删除某些特定元素，那么您可以将数组（不可变）转换为列表（可变），并按照以下方式处理：

var splitArray = str.Split(delimiterChar, StringSplitOptions.RemoveEmptyEntries);

Answer 2

这可能是可能获得理想结果的解决方案之一。

string str = "\n\nThis\nString\nis\nsplit\ninto\narray";
str = str.TrimStart('\n');
var splitArray = str.Split('\n');

Answer 3

是的，但有时字符串在前3个索引中包含随机字符串..   所以我想通过拆分将这个简单的字符串拆分成数组并删除。

split数组是简单的字符串数组，但为什么不能删除前2个项

将其拆分，然后使用Linq跳过任意数量的项目：

// I am skipping 3 for example
var splitArray = str.Split(delimiterChar).Skip(3).ToList();

确保将其添加到using语句列表中：

using System.Linq;

c＃split string
