    {
        //string A = txtInput.Text;
        string[] arrText = txtInput.Text.Split(',');
        int[] newOne = new int[]{};
        foreach (string r in arrText)

int[] newOne = arrText.Select(x => int.Parse(x)).OrderByDescending(x => x).ToArray();

You should be able to do it like this:

private void btnCalc_Click(object sender, EventArgs e)
{
    //string A = txtInput.Text;
    string[] arrText = txtInput.Text.Split(',');
    txtOutput.Text = string.Join(",",arrText.Select( s => int.Parse(s)).OrderByDescending( i => i))
}

Note that this will blow up if some of the input text between the commas is not a number.

this should work:

var newOne = arrText.OrderByDescending(int.Parse).ToArray();

foreach (var s in newOne)
{
      txtOutput.AppendText(s);
}
