Public Function Add ( _
    value As Attribute _

Parameters

value
Type: Attribute

The Attribute to be added to the end of the collection.

Return Value

Type: Int32
The index at which the value has been added.

Exceptions

Exception	Condition
ArgumentException	value cannot be placed on a class.
ArgumentNullException	The attribute is nulla null reference (Nothing in Visual Basic).

Remarks

Attributes are added in the order you would expect them to be declared on the class. The following code example shows how to add attributes that would be declared on a physical class.

[Browsable(true)]
[Description("Hello world")]
public class MyClass {}

The following code example shows the order in which to add attributes.

Add(new DescriptionAttribute("Hello world"));
Add(BrowsableAttribute.Yes);

Attributes that are marked as "allow multiple" will be added multiple times, while those not marked with "allow multiple" will only be added once, with the last one added taking precedence. This is in the same manner as a compiler.
