Correct way of searching a string for character in C#

Question

Hi All I need to search a string for an '=' sign string Text = ; int Gotit = 0; Text = richTextBox2.Text; Gotit = Text.IndexOf(=71); //MessageBox.Show(richTextBox2.Text); if (Gotit >1) { MessageBox.Show(Got It!); } The bit of code above will find the equals at a set location (where it happens to be in the string) What I need to is search to see if Text has more than one '=' in it. My thinking was use the above code to find one '=' something like the below if (Gotit >1) { //MessageBox.Show(Got It!); for (int a = 7; a { Gotit2 = Text.IndexOf(= a 1); MessageBox.Show(Hello); break; } bearing in mind the following Text.Length will always be greater than 7 the location of the first '=' this however seems to detect the first '=' (and only one if there is only one) in Text. HELP! Glenn =-=- Also why is a++ unreachable is due to the compiler seeing Text being equal to  at compile time but when it is used Text.Length does not equal 0 -=-=-=

Here's another traditional way of doing it which you sometimes see trotted out in response to questions such as this as it's only one line: int count = Text.Split('=').Length - 1; Personally I've never been keen on this approach as the Split method creates an array which then needs to be garbage collected. The LINQ approach also one line would be: int count = Text.Count(c => c == '='); That also does some fancy footwork behind the scenes but is much loved by many developers nowadays :)

Using traditional code (i.e. not regular expressions or LINQ) you could do this: int count = 0; foreach(char c in Text) { if (c == '=') count++; } MessageBox.Show(The number of equals signs found is  + count.ToString());
