Usage of StreamWriter

Question

I'm using the following code to open a file and then trying to write something to it:

public partial class MainWindow : Window
{
    StreamWriter file = null;
    public MainWindow()
    {
        InitializeComponent();
        using (file = new StreamWriter("../data/floorPlane.txt", true))
        {
            file.WriteLine("x \t y \t z \t w \n");
        }
    }
}

But it always gives the following error:

A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll

Additional information: 'The invocation of the constructor on type 'SkeletalViewer.MainWindow' that matches the specified binding constraints threw an exception.

I'm totally new to c#. Maybe the question is kindof stupid.

Thanks,

Your exception has nothing to do with the code you are showing — quantdev, Jun 04 '14 at 05:42

Obviously there's another problem in there. Read the exception carefully. There's a problem with some binding. — Ondrej Janacek, Jun 04 '14 at 05:44
Are you sure you have given the **correct** *relative path* of txt file ? — Kurubaran, Jun 04 '14 at 05:45
Exceptions which occur in the ctor of a WPF control will have this exception. You must look in the inner exception to see the actual problem. — GEEF, Jun 04 '14 at 05:47

First, check the inner exception to see what you are actually messing up. Then, if the answer is still not apparent, compare your code to the sample found at this MSDN article: http://msdn.microsoft.com/en-us/library/vstudio/system.io.streamwriter
