Question

I use a simple array: contentHouseOne[] that contains strings. But in the Do/While loop it isn’t working! It seems like the code don’t understand that it’s a string when a new object is to be created!? It works when I hardcode the string like I show below. Help is preciated! Thanks!

This isn’t working:

listHouseParts.Add(new HousePart(content, contentHouseOne[i], newPosition));

But this works:

 listHouseParts.Add(new HousePart(content, "100x100", newPosition));

EDIT:

Here are some code to declare arrays

string[] contentHouseOne = new string[] { "ruta100x100Red", 
                                          "ruta100x100Grey", 
                                          "ruta100x100Green", 
                                          "ruta100x100Yellow", 
                                          "ruta100x100Blue" };

bool[,] occupiedPositions = new bool[500,500];

Here are some code to set all grid positions to false

for (int i = 0; i < gridCol; i++)
    for (int ii = 0; ii < gridRow; ii++)
        occupiedPositions[i, ii] = false;

And finally here are the code that I have the problem

int i = 0;
do
{
    Vector2 newPosition = NewRandomPosition;
    if (occupiedPositions[(int)newPosition.X, (int)newPosition.Y] == false)
    {
        listHouseParts.Add(new HousePart(content, 
                                         contentHouseOne[i], newPosition));
        occupiedPositions[(int)newPosition.X, (int)newPosition.Y] = true;
        i++;
    }
}
while (i <= 5);

Your string array includes five elements:

string[] contentHouseOne = new string[] { "ruta100x100Red",
                                          "ruta100x100Grey", 
                                          "ruta100x100Green", 
                                          "ruta100x100Yellow", 
                                          "ruta100x100Blue" };

But your while loop ends if your running variable i is greater than 5

while (i <= 5);

which causes a IndexOutOfBounds exception on contentHouseOne, because the 6th element at index 5 isn’t defined.
You should change your while condition to (i < 5).
