how to get every element of a string?

how to get every element of a string?

• Memroid

  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!

  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..

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

  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);

  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

  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];
