how do I get the count of the occurrences of '#' in a string ?

something like int RowFormat = drr[3].ToString("#").Length;

example string "grtkj####mfr "

RowFormat must return 4

and yes ^_^ .NET 3.5

---

int RowFormat = "grtkj####mfr".Count(ch => ch == '#');

---

With LINQ (that's all the rage these days):

int RowFormat = drr[3].Count(x => x == '#');

---

Check this

"grtkj####mfr".Split(new char[]{'#'}).Length-1

hope that will help.

int RowFormat = new Regex("#").Matches("grtkj####mfr").Count;
