Namespace:  System

        name:string -> Object  
override GetData : 
        name:string -> Object

Parameters

name
Type: System.String

The name of a predefined application domain property, or the name of an application domain property you have defined.

Return Value

Type: System.Object
The value of the name property, or a null reference (Nothing in Visual Basic) if the property does not exist.

Implements

_AppDomain.GetData(String)

ExceptionCondition
ArgumentNullException

name is a null reference (Nothing in Visual Basic).

AppDomainUnloadedException

The operation is attempted on an unloaded application domain.

Use this method to retrieve the value of an entry in an internal cache of name-data pairs that describe properties of this instance of AppDomain. Note that the comparison of name with the name of key-value pairs is case-sensitive.

The cache automatically contains predefined system entries that are inserted when the application domain is created. You can inspect their values with the GetData method, or the equivalent AppDomainSetup properties.

You can insert or modify your own user defined name-data pairs with the SetData method and inspect their values with the GetData method.

The following table describes the name of each predefined system entry and its corresponding AppDomainSetup property.

Value of 'name'

The following example creates a new application domain, sets a system-provided value for the domain, and adds a new value pair for the domain. The example then demonstrates how to use the GetData method to retrieve the data from these value pairs and display them to the console.
