拆分并连接 C# 字符串 [英] Split and join C# string

问题描述

可能的重复:
先拆分然后加入字符串的子集

我试图将一个字符串拆分成一个数组，取出第一个元素(使用它)，然后将数组的其余部分连接成一个单独的字符串.

I'm trying to split a string into an array, take first element out (use it) and then join the rest of the array into a seperate string.

示例:

theString = "Some Very Large String Here"

会变成:

theArray = [ "Some", "Very", "Large", "String", "Here" ]

然后我想设置变量中的第一个元素并在以后使用它.

Then I want to set the first element in a variable and use it later on.

然后我想将数组的其余部分连接成一个新字符串.

Then I want to join the rest of the array into a new string.

所以它会变成:

firstElem = "Some";
restOfArray = "Very Large String Here"

我知道我可以使用 theArray[0] 作为第一个元素，但是我如何将数组的其余部分连接到一个新字符串?

I know I can use theArray[0] for the first element, but how would I concatinate the rest of the array to a new string?

推荐答案

你可以使用 string.Split 和 string.Join :

You can use string.Split and string.Join:

string theString = "Some Very Large String Here";
var array = theString.Split(' ');
string firstElem = array.First();
string restOfArray = string.Join(" ", array.Skip(1));

如果你知道你总是只想拆分第一个元素，你可以使用:

If you know you always only want to split off the first element, you can use:

var array = theString.Split(' ', 2);

这样您就不必加入:

string restOfArray = array[1];
