Can only display array by iterating through a for loop

Question

Hello I am trying to make a C# program that downloads files but I am having trouble with the array.

I have it split up the text for downloading and put it into a 2 level jagged array (string[][]).

Now I split up the rows up text by the | char so each line will be formatted like so: {filename}|{filedescription}|{filehttppath}|{previewimagepath}|{length}|{source}

when I use short test text to put it into a text box it displays fine in the text box.

IE: a string like test|test|test|test|test|test

but if I put in a real string that I would actually be using for the program to DL files the only way I get the string to display is to iterate through it with a for or foreach loop. If I try to access the data with the index I get an index missing error. (IE array[0])

So this is the code that gets the array to display:

public Form2(string[][] textList, string path)
{
    InitializeComponent();
    textBox1.Text = textBox1.Text + path + Environment.NewLine;
    WebClient downloader = new WebClient();
    foreach (string[] i in textList)
    {
        for(int j=0;j<i.Length;j++)
        {
            textBox1.Text = textBox1.Text + i[j] + Environment.NewLine + @"\\newline" + Environment.NewLine;
        }
    }
}

And then this is the code that gives an index missing error:

public Form2(string[][] textList, string path)
{
    InitializeComponent();
    textBox1.Text = textBox1.Text + path + Environment.NewLine;
    WebClient downloader = new WebClient();
    foreach (string[] i in textList)
    {
        textBox1.Text = textBox1.Text + i[0] + Environment.NewLine;
        textBox1.Text = textBox1.Text + i[1] + Environment.NewLine;
        textBox1.Text = textBox1.Text + i[2] + Environment.NewLine;
        textBox1.Text = textBox1.Text + i[3] + Environment.NewLine;
        textBox1.Text = textBox1.Text + i[4] + Environment.NewLine;
        textBox1.Text = textBox1.Text + i[5] + Environment.NewLine;
    }
}

Any help is this is apreciated I don't see why I can access they data through a for loop but not directly it just doesn't make any sense to me.

Also, here is the code that generates the array:

public String[][] finalList(string[] FileList)
{
    String[][] FinalArray = new String[FileList.Length][];
    for (int i = 0; i<FinalArray.Length;i++)
    {
        string[] fileStuff = FileList[i].Split(new char[] {'|'});
        FinalArray[i] = fileStuff;
    }
    return FinalArray;
}

Answer 1

In your first example you are using the actual length of each inner array to do the concatenation. In your second example you are hard coded to the same length yet you said in the intro it was a jagged array.

Can you show what your input text looks like?

you are not doing the same concatenation in first and second example so the resulting stings are very different.

        first = "\r\n Crazy Video\r\n\\\\newline\r\nThis Video is absolutly crazy!\r\n\\\\newline\r\nhtt://fakeurl.fake/vidfolder/video.flv\r\n\\\\newline\r\nhtt://fakeurl.fake/imgfolder/img.j‌​pg\r\n\\\\newline\r\n300\r\n\\\\newline\r\nhtt://fakeurl.fake \r\n\\\\newline\r\n"

        second = "\r\n Crazy Video\r\nThis Video is absolutly crazy!\r\nhtt://fakeurl.fake/vidfolder/video.flv\r\nhtt://fakeurl.fake/imgfolder/img.j‌​pg\r\n300\r\nhtt://fakeurl.fake \r\n"

Answer 2

Are you sure each String[] in string[][] textList has 6 elements?
