ContractOptionAttribute Constructor (String, String, String)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Initializes a new instance of the ContractOptionAttribute class by using the provided category, setting, and value.

Namespace:  System.Diagnostics.Contracts
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Sub New ( _
	category As String, _
	setting As String, _
	value As String _
)

Parameters

category
Type: System.String
The category of the option to be set.
setting
Type: System.String
The option setting.
value
Type: System.String
The value for the setting.

There are only two category/setting options, and they can be set by either of the constructor overloads. You can use this overload with the same settings as the ContractOptionAttribute overload by specifying "true" or "false" in string format; for example:

[ContractOption("contract", "inheritance", “false”)]
class MyConcurrentList<T> : IList<T> {
   ...
}
