HI guys

C#

km =Convert.ToDecimal(txtKMPerHr.Text);




foreach(decimal v in km.ToString())

What is happing is complicated (and very, very silly)
foreach loops round providing one at a time each of the items in the list of items to teh right of the in keyword. Each time round, the item is provided in the variable v which is declared on the left side of the in keyword.

In you case, km.ToSting() returns a string, which when treated as an iterator =by anything (including foreach) retunrs a sequence of char - so:

C#

foreach (char c in "hello")
    {
    Console.WriteLine(c);
    }

Would give you:

h
e
l
l
o

Your code forces the char to be a decimal so each digit in the original decimal value is handed to you as a decimal in v. Your number in txtKMPerHr.Text starts with '2', so the first value passed to the loop is 50 - ASCII value of the character '2'

As I said - very silly. But what of earth are you trying to do that you think that this would help? :laugh:
