You can use following solutions

var str="this is my string";
int characterCount;

 Solution I)

Remove the character and compare its length:

characterCount = str.Length - str.Replace("s", "").Length;

 Solution II)

Split the string into an array using the character as a delimiter:

characterCount = str.Split('s').Length - 1;

Solution III)

Use the LINQ 'Count' extension method:

characterCount = str.ToCharArray().Count(c => c == 's');
