The difference between MyString 0  and MyString ToCharArray   0  is that the former treats the string as a read-only array  while ToCharArray   creates a new array  The former will be quicker  along with easier  for almost anything where it will work  but ToCharArray can be necessary if you have a method that needs to accept an array  or if you want to change the array   If the string isn t known to be non-null and non-empty you could do   string IsNullOrEmpty MyString     char  null   MyString 0    which returns a char  of either null or the first character in the string  as appropriate

Answer to your question is NO   Correct is MyString position of character   For your case MyString 0   0 is the FIRST character of any string   A character value is designated with    single quote   like this x character value is written as  x    A string value is designated with     double quote   like this x string value is written as  x    So Substring   method is also does not return a character  Substring   method returns a string     A string is an array of characters  and last character must be   0   null  character  Thats the difference between character array and string   which is an array of characters with last character as  end of string marker    0  null   And also notice that  x  IS NOT EQUAL to  x   Because  x  is actually  x    0
