Splitting a String into only 2 parts

I want to take a string from a textbox (txtFrom) and save the first word and save whatever is left in another part. (the whatever is left is everything past the first space)

Example string = "Bob jones went to the store"

array[0] would give "Bob"
array[1] would give "jones went to the store"

I know there is string[] array = txtFrom.Split(' '); , but that gives me an array of 6 with individual words.

and as method with long delimter:

public string[] SplitInTwoParts(string source, string delimiter){
    string[] items = source.Split(new string[] { delimiter }, StringSplitOptions.None);

    string firstItem = items[0];
    string remainingItems = string.Join(delimiter, items.Skip(1).ToList());
    return new string[] { firstItem, remainingItems };
}

You simply combine a split with a join to get the first element:

string[] items = source.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);

string firstItem = items[0];
string remainingItems = string.Join(" ", items.Skip(1).ToList());

You simply take the first item and then reform the remainder back into a string.

char[] delimiterChars = { ' ', ',' };
string text = txtString.Text;

string[] words = text.Split(delimiterChars, 2);

txtString1.Text = words[0].ToString();
txtString2.Text = words[1].ToString();

You can also try RegularExpressions

Match M = System.Text.RegularExpressions.Regex.Match(source,"(.*?)\s(.*)");
M.Groups[1] //Bob
M.Groups[2] // jones went to the store

The regular expression matches everything up to the first space and stores it in the first group the ? mark tells it to make the smallest match possible. The second clause grabs everything after the space and stores it in the second group

There is an overload of the String.Split() method which takes an integer representing the number of substrings to return.

So your method call would become: string[] array = txtFrom.Text.Split(' ', 2);

Use String.Split(Char[], Int32) overload like this:

string[] array = txtFrom.Text.Split(new char[]{' '},2);
