Question

I have two classes and a method like this:

public class Class1 
{
    public int Id { get; set; }
    public string Name { get; set; }
    public Class2 Params { get; set; }
}

public class Class2
{
    public string Param1 { get; set; }
    public string Param2 { get; set; }
    public string Param3 { get; set; }
}

private Class1 GetData(SqlDataReader reader)
{
var model = new Class1
    {
        Id = Convert.ToInt32(reader["ID"]),
        Name = reader["Name"].ToString(),
        Class2.
    };
}

Why I cannot see the properties of Class2?

Dave is correct. The easiest way to do this with your code is as follows

private Class1 GetData(SqlDataReader reader)
{
    var model = new Class1
    {
        Id = Convert.ToInt32(reader["ID"]),
        Name = reader["Name"].ToString(),
        Params = new Class2()
     };
 }
