I am trying to take a class item and insert it into a MDF file.

I am having trouble equating the "List" classlist to its individual columns.

How do I break classlist down to its individual components?

C#

public class Class1
    {
        public Int32 id { get; set; }
        public string col1 { get; set; }
        public string col2 { get; set; }
        public string col3 { get; set; }
    }

C#

List<Class1> classlist = new List<Class1>();
            classlist.Add(new Class1() { id = 1, col1 = "11", col2 = "22", col3="33" });
            classlist.Add(new Class1() { id = 2,  col1 = "44", col2 = "55", col3="66" });
            classlist.Add(new Class1() { id = 3,  col1 = "77", col2 = "88", col3="99" });
            string connStr = ConfigurationManager.ConnectionStrings["MDFdb"].ConnectionString;
            string cmdStr = "INSERT INTO [Table1] (col1,col2,col3) VALUES (@col1,@col2,@col3);";
            for (int n; n<25; n++)
            {
            using (SqlConnection conn = new SqlConnection(connStr))
            {
                using (SqlCommand cmd = new SqlCommand(cmdStr, conn))
                {
                    conn.Open();
                    cmd.ExecuteNonQuery();
                    cmd.Parameters.Add("@col1", classlist[n,1]);
                    cmd.Parameters.Add("@col2", classlist[n,2]);
                    cmd.Parameters.Add("@col2", classlist[n,3]);
                }
            }
            }

classlist[n].col1 does not work for you? Keep in mind that when n > 3, you are going to get an exception.

Solution 1

classlist is a list of classes of type Class1 which appear to have properties id, col1, col2, etc.

So, you could access it like this:

C#

classlist[n].id
classlist[n].col1
...

Since classlist[n] will be an instance of Class1. Intellisense should show you this.
