Question

So, I wanna know how to write the entire content of an array to a textbox by using a foreach loop in C#. My code currently looks like this:

I generate a series of random numbers which are stored in the array:

int[] iData;

Now I want to write the stored data in this array to a textbox by using the foreach loop like this:

        foreach (int myInt in iData)
        {
            txtListing.Text = myInt.ToString();
        }

This will only write the last generated number in the array to the textbox, but my question is how do I write all of them to the tekstbox.

I only know, how to do this with a listbox and a forLoop. But is there any way this can be done with a textbox and a foreach loop?

Answer 1

Try using the AppendText method instead:

foreach (int myInt in iData)
{
    txtListing.AppendText(myInt.ToString());
}

Another option is to join the elements together as a string:

textListing.Text = string.Join(string.Empty, iData);

…or if you want another delimiter:

textListing.Text = string.Join(", ", iData);
