在Windows CE C＃中记录错误

Question

I'm writing a Windows CE App and want to implement error logging to a .txt file.

I've done research and saw this example:

public static void Logs(string fileName, string methodName, string message)
    {
        try
        {
            if (!string.IsNullOrEmpty(message))
            {
                using (FileStream file = new FileStream(Application.StartupPath + "\\Log.txt", FileMode.OpenOrCreate, FileAccess.Write))
                {
                    StreamWriter streamWriter = new StreamWriter(file);
                    streamWriter.WriteLine((((System.DateTime.Now + " - ") + fileName + " - ") + methodName + " - ") + message);
                    streamWriter.Close();
                }
            }
        }
        catch
        {
        }
    } 

private void button2_Click(object sender, EventArgs e)
    {
        try
        {
            int a = 10, b = 0;
            int result = a / b; //runtime Exception will throw
        }
        catch (Exception ex)
        {
            Logs(this.GetType().Name, "button1_Click()", ex.Message.ToString());
        }
    }

That works but only in Windows Forms. I'm getting this error in Windows CE:

'System.Windows.Application' does not contain a definition for 'StartupPath'

Ok, so I know I have to use this:

Path.GetDirectoryName (Assembly.GetExecutingAssembly ().GetName ().CodeBase);

But I'm not sure how. Still learning so please don't mark this as duplicate. Can someone rather just explain to me exactly where and how to use this in Windows CE app?

Thanks in advance.

Answer 1

You can write a function that returns the path of the executing assembly... just like:

public static string GetCurrentApplicationPath() 
{
  return System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
}

and use this function in place of Application.StartupPath
