[c#] Split and join C# string

Possible Duplicate:
First split then join a subset of a string

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.

Example:

theString = "Some Very Large String Here"

Would become:

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

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

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

So it would become:

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

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?

You can split and join the string, but why not use substrings? Then you only end up with one split instead of splitting the string into 5 parts and re-joining it. The end result is the same, but the substring is probably a bit faster.

string lcStart = "Some Very Large String Here";
int lnSpace = lcStart.IndexOf(' ');

if (lnSpace > -1)
{
    string lcFirst = lcStart.Substring(0, lnSpace);
    string lcRest = lcStart.Substring(lnSpace + 1);
}

Well, here is my "answer". It uses the fact that String.Split can be told hold many items it should split to (which I found lacking in the other answers):

string theString = "Some Very Large String Here";
var array = theString.Split(new [] { ' ' }, 2); // return at most 2 parts
// note: be sure to check it's not an empty array
string firstElem = array[0];
// note: be sure to check length first
string restOfArray = array[1];

This is very similar to the Substring method, just by a different means.
