C# How do I remove values for a specific item in the database

Question

I'm having problems deleting from my database

I have the following

Member thisMember = db.Members.First(m => m.MemberID == member.MemberID);
db.Members.Remove(thisMember.Name);
db.Members.Remove(thisMember.LastName);

But I keep getting an invalid arguments error. Can someone assist me?

Thanks!

db.Members.Remove is used to remove whole record (row/object) from data source. So you can remove whole member like this:

db.Member.Remove(thisMember);

If you want to set values of thisMember then you can do it like this:

Member thisMember = db.Members.First(m => m.MemberID == member.MemberID);
thisMember.Name = "";
// provided that it allows null value
thisMember.LastName = null;
// save changes in data source
db.SaveChanges();
