How do I get the count of attributes that an object has?

Question

I've got a class with a number of attributes, and I need to find a way to get a count of the number of attributes it has. I want to do this because the class reads a CSV file, and if the number of attributes (csvcolumns) is less than the number of columns in the file, special things will need to happen. Here is a sample of what my class looks like:

    public class StaffRosterEntry : RosterEntry
    {
        [CsvColumn(FieldIndex = 0, Name = "Role")]
        public string Role { get; set; }

        [CsvColumn(FieldIndex = 1, Name = "SchoolID")]
        public string SchoolID { get; set; }

        [CsvColumn(FieldIndex = 2, Name = "StaffID")]
        public string StaffID { get; set; }
    }

I tried doing this:

var a = Attribute.GetCustomAttributes(typeof(StaffRosterEntry));
var attributeCount = a.Count();

But this failed miserably. Any help you could give (links to some docs, or other answers, or simply suggestions) is greatly appreciated!

Answer 1

Please use the following code:

Type type = typeof(YourClassName);
int NumberOfRecords = type.GetProperties().Length;

Answer 2

This is untested and just off the top of my head

System.Reflection.MemberInfo info = typeof(StaffRosterEntry);
object[] attributes = info.GetCustomAttributes(true);
var attributeCount = attributes.Count();
