Question

For example i have a long[] x
And im doing:

for (int i=0; i<x.length;x--)
{
}

I know that in x for example i have 30 indexs cells.
How can i loop over the cells(indexs) in the x array and find on each cell the length of it and also to get/show the numbers in each cell.

If in x[0] there is 232
And in x[1] there is 21
And so on…

I want to display 232,21,….etc
And then i want to check that if x[i].length is above 0 do…
But there is no x[i].length

So how do i do it ?

I did:

public long GetHistogramMaximum(long[] histogram)
        {
            long result = 0;
            long count = 0;

            for (int i = 0; i < histogram.Length; i++)
            {
                if (histogram[i] > 0)
                {
                    MessageBox.Show(histogram[i].ToString());
                    break;
                }

            }

            return result;




        }

And its working but each time its showing me the number twice why the messagebox is working twice each time ?
If in the first array the number is 33454 then i see the messagebox once and then once again. Whats wrong here ? I want it to show me the number only once each time.

Its like repeating each number and show it once and then once again and only then moving to the next one.

EDIT **

Maybe the problem its showing the number twice each time have something to do with the scroll event im using ?

void trackBar1_Scroll(object sender, EventArgs e)
        {
            myTrackPanelss1.trackBar1.Minimum = 0;
            myTrackPanelss1.trackBar1.Maximum = counter - 1;//list_of_histograms.Count-1;
            long[] tt = list_of_histograms[myTrackPanelss1.trackBar1.Value];
            histogramControl1.DrawHistogram(tt);
            long res = GetTopLumAmount(tt, 1000);
            long max = GetHistogramMaximum(tt);
            if (res > -1)
            label24.Text = (res / 1000.0).ToString();
            setpicture(myTrackPanelss1.trackBar1.Value);
            this.pictureBox1.Refresh();
        }

For some reason its getting to the scroll and do everything here again. Twice in a row.
What can be the problem ?

Answer 1

A long[] basically holds a number of long values. Doing x[i].length is invalid, because a long does not have a property length. What is it that you are trying to achieve?

long[] x = {1,2,3} ;
x.length; //this is valid because you are querying the length / count of the array
x[0].length; //this is invalid because 1 does not have a property length

EDIT

Your loop counter will be the index. So,

for (int i =0; i < x.Length; i++)
{
   //check for maximum, when you find it
   Console.WriteLine("The maximum value is " + x[i]);
   Console.WriteLine("The maximum value is present at index " + i);
}
