Question

i am making an application which will load and save settings in an xml file. i searched thru all those questions and answers and tried all those methods and i didn’t find solution to my problem. here is the code:

private void DocumentToPrint_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        int x1 = 1;            
        XmlReader reader = XmlReader.Create("settings.xml");
        while (reader.Read())
        {
            if ((reader.NodeType == XmlNodeType.Element) && (reader.Name == "coordinates"))
            {
                if (reader.HasAttributes)
                {
                    x1 = int.Parse(reader.GetAttribute("tekst1x"));
                }

            }
        }
        reader.Close();

        var line1 = textBox1.Text;
        Font PrintFont = this.textBox1.Font;
        SolidBrush PrintBrush = new SolidBrush(Color.Black);
        e.Graphics.DrawString(line1, PrintFont, PrintBrush, x1, 30, new StringFormat());
        PrintBrush.Dispose();
    }

so its always showing me

this error:

Use of unassigned local variable ‘x1’ even i do have x1 assigned to 1.

on this line

e.Graphics.DrawString(line1, PrintFont, PrintBrush, x1, 30, new StringFormat());

any help will be appreciated. thanks in advance and best wishes.

i edit the question and added the full code

Answer 1

The given code does compile well. It seems like an issue with the IDE. I suppose it’ll be enough to Clean andRebuild the solution. However if it does not help, you may try to restart Visual Studio.
