1. ObsoleteAttribute
ObsoleteAttribute applies to all program elements except assemblies, modules, parameters, and return values. Marking an element as obsolete informs users that the element will be removed in future versions of the product.
Message property contains a string that will be displayed when the attribute assignee is used. It is recommended a workaround to be provided in this description.
IsError– If set to true the compiler will indicate an error if the attribute target is used in the code.
public static class ObsoleteExample
{
// Mark OrderDetailTotal As Obsolete.
[ObsoleteAttribute("This property (DepricatedOrderDetailTotal) is obsolete. Use InvoiceTotal instead.", false)]
public static decimal OrderDetailTotal
{
get
{
return 12m;
}
}
public static decimal InvoiceTotal
{
get
{
return 25m;
}
}
// Mark CalculateOrderDetailTotal As Obsolete.
[ObsoleteAttribute("This method is obsolete. Call CalculateInvoiceTotal instead.", true)]
public static decimal CalculateOrderDetailTotal()
{
return 0m;
}
public static decimal CalculateInvoiceTotal()
{
return 1m;
}
}
