how to get every element of a string?

  What He Said!
  
  Also, if you want to get at an individual char in a string for any reason, just use the index operator:
  
  string str = "ABCDEFG";
  int index = 2;
  char ch = str[index];

  I find one way,

  string p = "";
  for (int j = 0; j < (i - 1); j++)
  {
  p = p + a[j];
  }

  So that I can get rid of the last element of the original string

  Is there any other method to realize this

  Thank you Jeremy!

  I will try your method..

  I searched just now, and find a way:

  string s = "123";
  string a = " ";
  IEnumerator Enum = s.GetEnumerator();
  while (Enum.MoveNext())
  {
  a = Enum.Current.ToString();
  }

  I will get a="3" by above method, is it OK

  Well, my purpose is to get the last element of the a string...

  Then, what should I do to subtract an element of string s After I know the last element of s is "3", I should get rid of this element and to store "12" to string s..

  It seems we can add two strings together just by "+", however, we can not subtract two strings by just "-", any suggestion

  Thank you!

  I don't really understand what you're trying to do...just remove the last character from a string
  
  Then you can just do:
  if (s.Length > 0)
  s = s.Substring(0, s.Length - 1);

  You could use Substring() to get a single-char string. You could also use ToCharArray() to get an array of chars.

  Yeah, I can access the last element of a string by ToCharArray();

  string s = "23456";
  char[] a = s.ToCharArray();
  int i = (int)a.Length;
  a[i - 1].ToString();

  Then, how can I get the modified string s = "2345"

  To convert a CharArray to a string, is there any method

  I will search around..
