C# XAML Code issues

Question

I'm trying to finish off this program but I have a few errors that I can't get rid of. I've been following the C# book I have as well and I can't seem to find missing steps. I'll post the XAML code and the regular code.

Errors I have are as followed...

Warning 3 Unreachable code detected

Error 1 The type or namespace name 'memberSince' could not be found (are you missing a using directive or an assembly reference?)

Error 4 The type or namespace name 'Member' could not be found (are you missing a using directive or an assembly reference?)

Error 5 The type or namespace name 'Member' could not be found (are you missing a using directive or an assembly reference?)

Error 6 Delegate 'System.Threading.ParameterizedThreadStart' does not take 0 arguments

Error 2 'BellRingers.MainWindow.memberSince' is a 'field' but is used like a 'type'

Answer 1

struct Member
{
   public string FirstName;
   public string LastName;
   public string TowerName;
   public bool IsCaptain;
   public DateTime MemberSince;
   public List<string> Methods;

}

then change your the saveData Method's signature to this.

private void saveData(string fileName, Member member)
{  ...}

Doing this cleared all of the errors for me.
