get property name from generic list

Environment: asp.net fx3.5

given

public class Product
{
    public int ProductId { get; set; }
    public string ProductName { get; set; }
    public decimal UnitPrice { get; set; }
}

i have a List<Product> collection.

is there a way to get the property names because i want them to be a header row in my csv file that i'm constructing?

so the result i'm looking for is a string = "ProductId,ProductName,UnitPrice"

You can use the TypeDescriptor class (which is more efficient than plain reflection):

string.Join(",", TypeDescriptor.GetProperties(instance).Select(p => p.Name))

String.Join(",", typeof(Product).GetProperties().Select(p => p.Name))

If you don't want to use Linq, you can just iterate through the PropertyInfo array returned by GetProperties and concatenate the names to a string.

var headers = this.GetType().GetProperties().Select(p => p.Name).Aggregate((p1, p2) => p1 + "," + p2);
