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.
