How to extract First & Last name using Regex in C#?

Question

Suppose we have text/string for example:
John Doe

In the above text/string there can be multiple spaces before, after and in between.

How to extract First & Last name and store in two different variables in LOWER Case?

Also how to extract first letter of both?

Such as,
first = john
last = doe
first_letter = j
last_letter = d

Answer 1

string str = "John Doe";
string [] arr=str.Split(" ");
foreach(string s in arr)
{
Console.WriteLine (s);
Console.WriteLine(s[0]);
}
OR LIKE THIS:

string first=arr[0];
string last=arr[1];
Console.WriteLine("FirstName: "+first+"\n"+"LastName: "+last);
Console.WriteLine("FirstLetter: "+first[0]+"\n"+"LastLetter: "+last[0]);
