Split string with fixed first element and second variables elements in c# [duplicate]

Question

My string :

it would be possible to split this string to two elements

first element

[email protected];

and second elments

 [email protected]; [email protected];

For insert

[email protected];

Into table_1 ?

and insert

 [email protected]; [email protected];

into table_2 ?

the number of element of part one will always be one

the number of elements of part two is variable, it could be one but also 10/100/500

I have tried this code without success

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        string value = "[email protected]; [email protected]; [email protected]";

        List<string> values = value.Split(';', StringSplitOptions.RemoveEmptyEntries).ToList();
        string Table1 = values[0];
        values.RemoveAt(0);
        string Table2 = string.Join(';', values).Trim();

        Console.WriteLine(Table1);
        Console.WriteLine(Table2);
    }
}

need more information?

@Sinatr if not necessary and not appreciated I can eliminate it, no problem. — Chevy Mark Sunderland

I like the coloration of this code. but for some reason I can't select and copy past in order to craft an answer. We live in a time where screen shoot is easier that copy past, so I have to type it? ;) — Drag and Drop

Yes, please remove unnecessary parts of the question, they are just noise. See how to ask. — Sinatr

There is an overload of Split that takes a maximum number of substrings - just set that to 2:

value = "[email protected]; [email protected]; [email protected];"
string[] values = value.Split(new [] {';'}, 2)
first = values[0]; //[email protected]
rest = values[1];  //[email protected]; [email protected];

From there you can trim spaces and/or add semicolons as necessary.
