如何从字符串列表中提取数组索引？ [英] how to extract array index from string list?

问题描述

我想知道如何提取某些数组索引并传入变量。我希望能够提取某些数组索引（即第一行和第二行的字符串），如下例所示：



字符串Array []名为：

93935NAA2

93935NAB0

93935QAB3

93935QAF4

939355AB9



仅读取第一行。

预期输出：

93935NAA2



从第二行开始读到列表末尾。

预期产出：

93935NAB0

93935QAB3

93935QAF4

939355AB9 < br $> b $ b



任何指南都将不胜感激。非常感谢

我想我明白你的意思，但如果没有，你需要更详细地解释一下。

  private  T [] Extract< T>（IEnumerable< T> input， int  startIndex，< span class =code-keyword> int  length = -1）
 {
  return  input.Skip（startIndex）。 Take（length >  =  0 ？length：input.Count（） -  startIndex）。ToArray（） ; 
} 

并测试它：

  string  [] names = {  93935NAA2，  93935NAB0，  93935QAB3，  93935QAF4，   939355AB9}; 
  string  [] one =提取（名称， 0 ， 1 ）; 
  string  [] some = Extract（names， 1 ）; 

I would like to know how I can extract certain array index and pass in variable. I would like to be able to extract certain array index (i.e. string from 1st line and 2nd second line), as shown below in the example:

String Array [ ] called Names:
93935NAA2
93935NAB0
93935QAB3
93935QAF4
939355AB9

Read first line only.
Expected output:
93935NAA2

Starts reading from second line till the end of the list.
Expected output:
93935NAB0
93935QAB3
93935QAF4
939355AB9


Any guide would be appreciated. Many Thanks

I think I see what you mean, but If not, you will need to explain in much better detail.

private T[] Extract<T>(IEnumerable<T> input, int startIndex, int length = -1)
    {
    return input.Skip(startIndex).Take(length >= 0 ? length: input.Count() - startIndex).ToArray();
    }

And to test it:

string[] names = { "93935NAA2", "93935NAB0", "93935QAB3", "93935QAF4", "939355AB9" };
string[] one = Extract(names, 0, 1);
string[] some = Extract(names, 1);
