String[] [RESOLVED]

Howdy all,


I am having a problem accessing the values of a string[] array;

Code:

---

//remove the leading spaces
                                        line = line.TrimStart(new char[] {' '});
                                        //Console.WriteLine(line);
                                        //find the parts to the line..
                                        line2 = line.Split(new char[] { ',' });
                                        //we now have, the parts to the line..
                                        left = line2[0].Split(new char[] { ' ' });
                                        //get the right side..
                                        right = line2[1];

---

It generates an Index was outside the bounds of an array error on the line:

Code:

---

right = line2[1];

---

Anyone know why?

The only way that can happen is if line2 doesn't contain any ',' characters, so when you try and split it the CLR returns a one element array which of course doesn't have a [1] index.

See, I know the basics of it. But if that was the problem, how come I can do it this way (im sure there is a more efficient way):

Code:

---


for (int i = 0; i < line2.GetUpperBound(0)+1; i++)
{
    right = line2[i];
}

//now right = what it should

//but this doesnt work
right = line2[1];

---

Is this weird?

No that isn't wierd. At first, you check and incriment until you hit the last element in the array, then you access an element NOT in the array. The loop you made obviously only gets run once (since the array's upper bound is [0], thus [1] doesn't work).

Your code that you use to split a file into a string is either wrong, or you didn't set the string array to a high enough number you need (array bounds must be declared at compile time)

See, I know what you mean. But if I have:

"Mondays Event,soccer"

line2[0] = "Mondays Event"

and line2[1] should = "soccer"

It returns an error when i use line2[1]

But, when i use that loop, and:

Code:

---

right = line2[i]

---

(Notice i used UpperBound(0)+1)

line2[1] equals "soccer" just like i want it to.


I will try when I am home to set the array to a fixed size. But I have seen them used before like I have.


[edit]
PS: I have it working how I want now. Just wondering why my first attempt didn't work, but the loop does.
