output multidimensional array to grid style textbox

Question

I am having trouble with text formatting while trying to output my array into a textbox.

I'm required to output something like this; https://i.sstatic.net/sX6AI.jpg sort of like a table minus the borders.

Ive managed to produce something similar, but i'm out of ideas. https://i.sstatic.net/rvAUY.jpg

My code is:

string[,] toys = new string[5, 4];
for (int week = 0; week <= 3; week++)
{
    for (int day = 0; day <= 4; day++)
    {
        toys[day, week] = Microsoft.VisualBasic.Interaction.InputBox("Please enter value for Day " + Convert.ToString(day + 1) + " in week " + Convert.ToString(week + 1) + ".");
    }
}
txtOutput.Text += "Mon" + "\t" + "Tue" + "\t" + "Wed" + "\t" + "Thu" + "\t" + "Fri" + "\t" + "\r\n";
txtOutput.Text += "Week 1" + "\t" + "\r\n";
txtOutput.Text += "Week 2" + "\t" + "\r\n";
txtOutput.Text += "Week 3" + "\t" + "\r\n";
txtOutput.Text += "Week 4" + "\t" + "\r\n";

foreach (string text in toys)
{

    txtOutput.Text += text + "\t";
}

Is this Silverlight, or Web Forms? Neither one has a textbox that works like this. — John Saunders

It's not the only wrong thing here but, why "Mon" + "\t" instead of "Mon \t" ? — Selman Genç

Oh i was taught to use the visual basic inputbox (for the current project im working on) so had to use that. Also was unaware i could code it that way "Mon \t", seems alot easier! — Mirro A

You still haven't said what kind of project this is. Visual Basic doesn't have any "inputbox", BTW. — John Saunders

The easiest way to do this is by drawing line by line as follows:

//first, set up the toys index by accepting some inputs
string[,] toys = new string[5, 4];
for (int week = 0; week <= 3; week++)
{
    for (int day = 0; day <= 4; day++)
    {
        toys[day, week] = Microsoft.VisualBasic.Interaction.InputBox("Please enter value for Day " + Convert.ToString(day + 1) + " in week " + Convert.ToString(week + 1) + ".");
    }
}


//then, print the output line by line by looping through the toys array
//the first line must be separate because the headings are not part of the array
txtOutput.Text += "Mon" + "\t" + "Tue" + "\t" + "Wed" + "\t" + "Thu" + "\t" + "Fri" + "\t" + "\r\n";

for (int week = 0; week <= 3; week++)//foreach week
{
    //construct the line of text which represents the week's data
    txtOutput.Text += "\tWeek " + (week+1) + "\t";
    for (int day = 0; day <= 4; day++)
    {
       txtOutput.Text += toys[day,week];
       if(day != 4)
       {
         //so long as it is not the last day, then you have to tab over
         txtOutput.Text += "\t";
       }
    }

    //wrap things up by moving to the next line before you iterate to the next line
    txtOutput.Text += "\r\n";
 }

I like this approach. Seems logical. Although its saying this part is not working. txtOutput.Text += toys[week, day];

AGB Over a year ago

Nevermind... I think I switched up your indexes on the toys array. See the edited code above, which should have fixed the issue.

Mirro A Over a year ago

Oh i see what you mean, its still saying "Index was outside the bounds of the array." for the: txtOutput.Text += toys[week,day];

AGB Over a year ago

that line of code should now read txtOutput.Text += toys[day,week]; it should not read txtOutput.Text += toys[week,day];

thanks for explaining it! Makes alot more sense now :)

just a little idea, you'd better init the titles(like "Mon", "Tue"..etc.. ) into the array, like this

string[,] toys = new string[,]
{
    {" ","Mon", "Tue", "Wed", "Thu", "Fri"},
    {"Week 1", "0", "0", "0", "0", "0"},
    {"Week 2", "0", "0", "0", "0", "0"},
    {"Week 3", "0", "0", "0", "0", "0"},
    {"Week 4", "0", "0", "0", "0", "0"}
};

and

toys[week + 1, day + 1] = Microsoft.VisualBasic.Interaction.InputBox(...

and when you output, use the GetLenght() cause toys[,] is a two-dimensional array.

for (int i = 0; i < toys.GetLength(0); i++)
{
    for (int j = 0; j < toys.GetLength(1); j++)
    {
        this.textBox1.Text += toys[i, j] + "\t";
    }
    this.textBox1.Text += "\r\n";
}

This way seems like alot more code? For this part: toys[week + 1, day + 1] = Microsoft.VisualBasic.Interaction.InputBox(... Would i have to paste that like for each day of the week? or loop it?

Rwing Over a year ago

toys[day + 1, week + 1] = Microsoft.VisualBasic.Interaction.InputBox("Please enter value for Day " + Convert.ToString(day + 1) + " in week " + Convert.ToString(week + 1) + ".");

Have you looked into the StringBuilder Class?

Ref- http://msdn.microsoft.com/en-us/library/system.text.stringbuilder(v=vs.110).aspx

StringBuilder myName = new StringBuilder(); 
myName.appendFormat("Name = {0}, hours = {1:hh}", myName, DateTime.Now); //For example.

That should be a good place to start.

Check out my way of doing it. I just read your message so yeah... Maybe this will also help in the future... This is the shortest I could think of :)

TextBox1.Text = "\t" + "Mon" + "\t" + "Tues" + "\t" + "Weds" + "\t" + "Thurs" + "\t" + "Fri";
for (int week = 0; week <= 3; week++)
    {
    TextBox1.Text += Environment.NewLine + "Week " + Convert.ToString(week + 1) + "\t";
    for (int day = 0; day <= 4; day++)
        {
        TextBox1.Text += toys[day, week] + "\t";
        }
    }
