The Integer.TryParse method takes a string as its first parameter and an integer variable as its second parameter. It attempts to parse the string and store its value in the integer variable. If successful, it returns true and the integer variable contains the parsed value; if not, it returns false and the integer variable is set to 0. So, in this case, the valid statement is "blnIsOK = Integer.TryParse(txtShirts.Text, intShirts)."
