Delete file using File.Delete and then using a Streamwriter to create the same file?

Question

public void LoadRealmlist()
    {
        try
        {
            File.Delete(Properties.Settings.Default.WoWFolderLocation + "Data/realmlist.wtf");
            StreamWriter TheWriter = new StreamWriter(Properties.Settings.Default.WoWFolderLocation + "Data/realmlist.wtf");
            TheWriter.WriteLine("this is my test string");
            TheWriter.Close();
        }
        catch (Exception)
        {

        }            
    }

Will my method properly delete a file, then create one with "realmlist.wtf" as the name and then write a line to it?

I'm kind of confused because I can't see the line where it actually creates the file again. Or does the act of creating a StreamWriter automatically create a file?

Answer 1

The Stream Writer will create the file if it doesn't exist. It will create it in the constructor, so when the StreamWriter is instantiated.

Answer 2

You know, if you pass a FileStream instance to the StreamWriter constructor, it can be set to simply overwrite the file. Just pass it along with the constructor.

http://msdn.microsoft.com/en-us/library/system.io.filestream.filestream.aspx

Example:

try
{
    using (FileStream fs = new FileStream(filename, FileMode.Create))
    {
        //FileMode.Create will make sure that if the file allready exists,
        //it is deleted and a new one create. If not, it is created normally.
        using (StreamWriter sw = new StreamWriter(fs))
        {
           //whatever you wanna do.
        }
    }
}
catch (Exception e)
{
    System.Diagnostics.Debug.WriteLine(e.Message);
}

Also, with this you won't need to use the .Close method. The using() function does that for you.

Try System.IO.File.CreateText
