Here is a really simple string extension to help you get initials from a string in C#
public static string ToInitials(this string str)
{
return Regex.Replace(str, @"^(?'b'w)w*,s*(?'a'w)w*$|^(?'a'w)w*s*(?'b'w)w*$", "${a}${b}", RegexOptions.Singleline)
}
Here’s a breakdown on what the expression is doing:
- ^ matches beginning of the string
- (?‘b’w) captures first character of a word and stores in in ‘b’
- w* matches the rest of the name
- , matches a comma
- s* matches > 0 spaces
- (?’a’w)w* matches the second part of the name capturing the first letter into ‘b’
- $ matches end of string
- | or the alternate pattern w ithout the ,
- Notice the ‘a’ and ‘b’ are swapped
