AppDomain.SetData Method (String, Object)

 

Assigns the specified value to the specified application domain property.

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

<SecurityCriticalAttribute>
Public Sub SetData (
	name As String,
	data As Object
)

Parameters

name
Type: System.String

The name of a user-defined application domain property to create or change.

data
Type: System.Object

The value of the property.

Exception Condition
AppDomainUnloadedException

The operation is attempted on an unloaded application domain.

Use this method to insert an entry, or modify the value of an entry in an internal cache of name-data pairs that describe properties of this instance of AppDomain.

The cache automatically contains predefined system entries that are inserted when the application domain is created. You cannot insert or modify system entries with this method. A method call that attempts to modify a system entry has no effect; the method does not throw an exception. You can inspect the values of system entries with the GetData method, or the equivalent AppDomainSetup properties described in GetData.

You can call this method to set the value of the default timeout interval for evaluating regular expression patterns by supply "REGEX_DEFAULT_MATCH_TIMEOUT" as the value of the name argument and a TimeSpan value that represents the timeout interval as the value of the data argument. You can also insert or modify your own user defined name-data pairs with this method and inspect their values with the GetData method.

The following example demonstrates how to use the SetData(String, Object) method to create a new value pair. The example then uses the GetData method to retrieve the value, and displays it to the console.

Imports System
Imports System.Reflection

Class ADGetData   

   Public Shared Sub Main()
      ' appdomain setup information
      Dim currentDomain As AppDomain = AppDomain.CurrentDomain

      'Create a new value pair for the appdomain
      currentDomain.SetData("ADVALUE", "Example value")

      'get the value specified in the setdata method
      Console.WriteLine(("ADVALUE is: " & currentDomain.GetData("ADVALUE")))

      'get a system value specified at appdomainsetup
      Console.WriteLine("System value for loader optimization: {0}", _
         currentDomain.GetData("LOADER_OPTIMIZATION"))

   End Sub 
End Class 

' This code example produces the following output:
'
'ADVALUE is: Example value
'System value for loader optimization: NotSpecified
