How to count characters in RichTextBox?

[engjulli]

Any one knows how to make statistic from richtextbox counting characters in detail, like a=20, b=7 etc. I know to find dhe absolute number of characters with function "richTextBox1.TextLength" but to access every character i'm not aible!!!
Please help!!!

Do you want to get the only the charcters in the richtextbox ?

I don't understand exactly what you want...(I don't know of any system where a=20 and b=7.)if you want to count the number of characters, use richTextBox1.Text.Length, it's an int value.
If you want to analyze every character and do something with it, you can use a foreach loop:

            foreach (Char c in richTextBox1.Text.ToCharArray())
                {
                MessageBox.Show(c.ToString()); //do whatever you want with "c" it will represent the current Char value
                }

Awkward way:

int[] char_counts = new int[26];
char[] chars = myrtb.Text.ToLower().ToCharArray();

// count characters:
foreach (char c in chars)
  ++char_counts[(int)c - (int)'a'];

// display them:
for (int i = 0; i <= 26; ++i)
  Console.WriteLine((char)(i + 96) + ": " + char_counts[i]);

Awesome way (but probably slower):

char[] chars = myRTB.Text.ToLower().ToCharArray();
int[] char_counts = new int[26];

for (int i = 0; i < char_counts.Length; ++i)
  char_counts[i] = Array.FindAll<char>(chars, delegate(char c) {
    return c == (char)(i + (int)'a'); }
  ).Length;

edit: actually, that would be a lot slower, because it has to make 26 passes over the string, as opposed to one. I just wanted an excuse to use predicates.
