I got a class like this:
namespace MYSCommon
{
[Serializable]
public class Cart
{
// Methods
public Cart(){
//Code skip
}
public double Value{
//Code skip
}
}
}
I use this method to call in the aspx, it got an error:
The code:
<%= MYSCommon.Cart.Value %>
The error:
Compiler Error Message: CS0120: An object reference is required for the nonstatic field, method, or property 'MYSCommon.Cart.Value'
But I got another like this:
namespace MYSCommon
{
public class Constant
{
// Fields
public static string staticValue = "Something";
}
}
and called it via: <%= MYSCommon.Constant.staticValue %>
, which is success.
How can I solve it? Thanks.
You can't access instance variable without the class instance. In the code behind of ascx
you may create a public instance of type Cart
like:
Code behind of ascx:
public MYSCommon.Cart myCart = new MYSCommon.Cart();
later you can access it like:
in ascx
:
<span> <%= myCart.Value %> </span>
Just make sure that myCart
is declared as public
and at Page
level.
