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


The value of the property.

Exception typeCondition


Operations are 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.

using System.Reflection;

class ADGetData 

	public static void Main() 
		// appdomain setup information
		AppDomain currentDomain = AppDomain.CurrentDomain;

		//set predefined system variable application name
		String dataName = "APP_NAME";
		String setappname = "MyApplication";
		currentDomain.SetData(dataName, setappname);

		//Create a new value pair for the appdomain
		String dataValue = "ADVALUE";
		Int32 advalue = 6;
		currentDomain.SetData(dataValue, advalue);

		//get the value specified in the setdata method
		Console.WriteLine(" ADVALUE is: " + currentDomain.GetData("ADVALUE"));

		//get system value specified at appdomainsetup
		Console.WriteLine("System value for application name:" + currentDomain.GetData("APP_NAME"));
