Question

Here my code:

using Excel = Microsoft.Office.Interop.Excel;

private void button1_Click(object sender, EventArgs e)
{
    Excel.Application xlApp = new Excel.Application();
    Excel.Workbook wb = xlApp.Workbooks.Add(System.Type.Missing);
    Excel.Worksheet ws = (Excel.Worksheet)wb.Sheets[1];
    xlApp.Visible = true;

    Excel.Shape textBox = ws.Shapes.AddTextbox(
        Microsoft.Office.Core.MsoTextOrientation.msoTextOrientationHorizontal,
        10 + 10 + 10, 36, 600, 100);
    textBox.TextFrame.Characters(System.Type.Missing, System.Type.Missing).Text
        = "testing";

    xlApp.ActiveWindow.Activate();
    xlApp.UserControl = true;
    ws = null;
    wb = null;
    xlApp = null;
}

But with this code I only can add one line text “testing”:

---------------------------------
|Testing                        |
|                               |
|                               |
---------------------------------

Now I want to add 3 line text, like this:

---------------------------------
|Test1                          |
|Test2                          |
|Test3                          |
---------------------------------

Somebody help me?

System.Environment.NewLine might be the constant you are looking for to separate your 3 strings.
