foreach item in class list

Question

I have a class like so:

public class OverDueClass
{
     public int CustomerID { get; set; }
     public int Question_ID { get; set; }
     public string Department { get; set; }
     public DateTime DueDate { get; set; }
}

And I am populating this class and passing it to another method:

while (dataReader.Read())
{
      OverDueClass overDueItem = new OverDueClass();

      overDueItem.CustomerID = (int)dataReader[0];
      overDueItem.Question_ID = (int)dataReader[1];
      overDueItem.Department = dataReader[2].ToString();
      overDueItem.DueDate = (DateTime)dataReader[3];

      OverDueCell.Add(overDueItem);
}  

sendEmail("[email protected]", OverDueCell);

Now in the other method, I can see the data is being passed.

Now I am trying to run a foreach to do something with the data and I tried the following:

foreach(string item in overDue)
{

}

But I get this error:

Cannot covert type to string.

overDue I'm assuming is a single OverDueClass, its not an array or collection, so you can't foreach over it. Are you trying to iterate through all the properties in the class? — Ron Beyer

@RonBeyer...Because he sent OverDueCell as a parameter to sendEmail method, I think overDue would be OverDueCell. — Salah Akbari

If the overDue is the OverDueCell then change string to OverDueClass in foreach like this:

foreach(OverDueClass item in overDue)
{

}

Or use var keyword:

foreach(var item in overDue)
{

}

If you are attempting to iterate thru the collection of OverDueItems:

foreach(var item in overDueItemsCollection)
{
    ...
}

If you are trying to iterate thru properties of OverDueItem:

PropertyInfo[] properties = typeof(overDueItem).GetProperties();
foreach (PropertyInfo property in properties)
{
    var value = property.GetValue(overDueItem);
    ...
}
