First split then join a subset of a string

我正在尝试将字符串拆分为数组，取出第一个元素(使用它)，然后将数组的其余部分合并为单独的字符串.

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"

将成为:

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

然后我要在变量中设置第一个元素，以后再使用它.

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到新字符串中.

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

因此它将变为:

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

我知道我可以将theArray[0]用作第一个元素，但是如何将数组的其余部分隐藏为一个新字符串呢?

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

您可以使用string.Split和string.Join:

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

如果您始终只想分割第一个元素，则可以使用:

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

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

这使您不必加入:

string restOfArray = array[1];
