You could treat the account number as a string and insert the dashes using String.Insert().

 

[Gill Bates]

Console.WriteLine(new System.Text.RegularExpressions.Regex("([0-9]{4})").Replace("4549163506238472","$1-").TrimEnd('-'));

This assumes that the length of your string % 4 == 0.

I solved this issue by using the following.



StringBuilder sb = new StringBuilder(argstring);
sb.Insert(4,"-");
sb.Insert(9,"-");
sb.Insert(14,"-");
return sb.ToString;




Thank u all for their effort

long l = 4549163506238472;
string s = l.ToString("0000-0000-0000-0000");

would be a quicker way.
