lowercase to uppercase: ToUpper ();

Uppercase to lowercase: toLower ();

Replacement: replace (' X ', ' Y ');

Converts a string to a character array: ToCharArray ();

Remove y characters from x: string.substring (ing x,int y);

Insert Y:string.insert (int x,string Y) at X;

Split with x: String. Split (' x ');

To verify the 18-bit ID number (including lowercase x):
