How to get the first five character of a String

asp.net, c#, char, string

Solution

You can use Enumerable.Take like:

char[] array = yourStringVariable.Take(5).ToArray();

Or you can use String.Substring.

string str = yourStringVariable.Substring(0,5);

Remember that `String.Substring` could throw an exception in case of string's length less than the characters required.

If you want to get the result back in string then you can use:

Using String Constructor and LINQ's `Take`

string firstFivChar = new string(yourStringVariable.Take(5).ToArray());

The plus with the approach is not checking for length before hand.

- The other way is to use `String.Substring` with error checking

like:

string firstFivCharWithSubString = 
    !String.IsNullOrWhiteSpace(yourStringVariable) && yourStringVariable.Length >= 5
    ? yourStringVariable.Substring(0, 5)
    : yourStringVariable;
