C# Array Question

Not sure why you are writing to the console when you have a GUI with text boxes.

Anyways, during execution of the while loop, do you expect the value of the text box to change? If so you need to handle that event.

Assuming that is not the case, going by your comment "//this line needs to get written 52 times and will change", the while loop should be like this.

        int i = 0;
        while (i < quan[0])
        {
            Console.WriteLine("Printing " + i + "th iteration of " + quan[0] + " from textbox1");
            i++;
        }

The code could be improved but is this close to what you are looking for?

or a simple loop will do, like:

int[] quan = new int[3];
            quan[0] = 52; //int.Parse(number1TextBox.Text);
            quan[1] = 98; //int.Parse(number2TextBox.Text);
            quan[2] = 28; //int.Parse(number3TextBox.Text);
            
for(int i = 0;i<quan[0];i++) {
...

if you need to do a nested loop, you can try like:

...
    for(int j = 0;j<quan[1];j++) {
        for(int k = 0;k<quan[2];k++) {
            Console.WriteLine("i="+(i+1) + ", j="+(j+1)+", k="+(k+1)+"The quantity of textbox x is: "+quan[0]);
        }
    }
}
...

There are two ways to do what you want to do. One will fill in the array ordered as q[0]  -> TextBox1, and q[1] -> TextBox2, etc.

The other will fill in them unordered and somewhat randomly, as in q[0] -> TextBox23, q[1] -> TextBox5, etc.

Here's the code for both ways. Note I simply created a WindowsForm application with four text boxes labeled TextBox1, TextBox2, TextBox3, and TextBox4. I filled them in and then have a button which gets the values.

Now, you can have as many textboxes as you want and there is no hardcoding of the textbox name. You just increment the number, ToString() it, and you have the values.

At the end of the loop, how to I advance to the next array [1]

My ultimate goal is to create one file for each array index.

int[] quan = new int[3];
            quan[0] = 52; //int.Parse(number1TextBox.Text);
            quan[1] = 98; //int.Parse(number2TextBox.Text);
            quan[2] = 28; //int.Parse(number3TextBox.Text);
           
for(int i = 0;i<quan[0];i++) {
Make file 1 but run the loop 52 times
for(int i = 0;i<quan[1];i++) {
Make file 2 but run the loop 98 times

and so one

and have a unique file name for each round

Ok, here is a better description of my code:

To clarify, I have 5 text boxes that take in a number.
I need to create 5 unique files.

Inside each file, a loop will run (x times per the textbox input) to generate a gallery with path and photo number

 int[] links = new int[5];
            links[0] = int.Parse(1TextBox.Text);
            links[1] = int.Parse(2TextBox.Text);
            links[2] = int.Parse(3TextBox.Text);
            links[3] = int.Parse(4TextBox.Text);
            links[4] = int.Parse(5TextBox.Text);


            string[] fileName = new String[5];
            fileName[0] = "one";
            fileName[1] = "two";
            fileName[2] = "three";
            fileName[3] = "four";
            fileName[4] = "five";

            int numLinks = 0;
            int ii = 0;

            for( int i = 0; 1 < fileName.Length; i++)
            {
                StreamWriter writer = new StreamWriter("C:\\csharp\\" + fileName[i] + ".html");
                writer.Write("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">");
                while (count < links[ii])
                {
                    string photoNum = startingPhotoNumber.ToString("D3");
					writer.Write("<img src=" + "photos/" + fileName[i]+photoNum + ".jpg' alt='Mountain View' style='width:304px;height:228px;'>");
                    count++;
                    ++startingPhotoNumber;
                }
                writer.Write("</div>");
                writer.Close();
                i++;
                MessageBox.Show("File Created");
            }

Hi,

That worked! Thanks.

Also, is there a way add in an alt tag based on the array as well?

            string[] altTag = new String[5];
            altTag[0] = "1";
            altTag[1] = "2";
            altTag[2] = "3";
            altTag[3] = "4";
            altTag[4] = "5";

For the array that you have shown just change the line 27 in my earlier comment as below:

writer.Write("<img src=" + "photos/" + fileName[i]+photoNum + ".jpg' alt='" + altTag[i] + "' style='width:304px;height:228px;'>");

that should work, if not post your question
