Question

i am still learning and fighting derived classes.

tried something simple ( from the examples i have seen all over ):

public class BaseClass
{
    public string Title {get;set;}
}

public class Channel : BaseClass
{
    public string Path { get; set; }
}


Channel myChannel = new Channel();
myChannel.Title = "hello";
myChannel.Path = "123";

but i get an error on the myChannel.Path line saying BaseClass does not contain a definition for Path and no extension....

help me please, what am i doing wrong?

Answer 1

The example you show is fine. I think in your actual code you have:

BaseClass myChannel = new Channel();
myChannel.Title = "hello";
myChannel.Path = "123";

so the answer is simply: ensure your local variable is typed as Channel, since it is the the expression type (typically: the type of a variable) that determines the starting point for member resolution.

As a terse alternative in C# 3:

var myChannel = new Channel { Title = "hello", Path = "123" };
