AppDomain.SetData Method (String, Object)

Assigns the specified value to the specified application domain property.

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

public void SetData(
	string name,
	Object data
)

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.

Implements

_AppDomain.SetData(String, Object)

ExceptionCondition
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. You can inspect their values with the GetData method, or the equivalent AppDomainSetup properties described in GetData.

You can 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.


using System;
using System.Reflection;

class ADGetData 
{
    public static void Main() 
    {
        // appdomain setup information
        AppDomain currentDomain = 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"));
    }
}

/* This code example produces the following output:

ADVALUE is: Example value
System value for loader optimization: NotSpecified
 */
