Important
We do not recommend that you use the Read
and Write
methods due to potential vulnerabilities if the input XML document contains names of untrusted assemblies and types. Validate or sanitize the input XML documents even in testing and non-production environments for the best security.
When a Session object uses the functionality of the InMemoryDataStore class, persistent objects are stored and loaded from RAM.
#Example
This example demonstrates how to store persistent objects in RAM.
To use RAM as a data store, a InMemoryDataStore
object is created and passed to the SimpleDataLayer object constructor. The created SimpleDataLayer object is assigned to the XpoDefault.DataLayer property and will be used by any Session object when a connection to a data store is to be established.
using DevExpress.Xpo;
using DevExpress.Xpo.DB;
XpoDefault.DataLayer = new SimpleDataLayer(new InMemoryDataStore());
