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.
The cache automatically contains predefined system entries that are inserted when the application domain is created. You can inspect their values with the 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 method.
The following table describes the name of each predefined system entry and its corresponding AppDomainSetup property.
Value of 'name'
"APP_LAUNCH_URL" represents the URL originally requested by the user, before any redirection. It is available only when the application has been launched with a browser such as Internet Explorer. Not all browsers provide this value.
The following code 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 method to retrieve the data from these value pairs and display them to the console.
