6.3. How to Use Data Virtualization

To enable the data virtualization, you should apply a custom attribute to your field. In order to do that, you can use the instructions below.

Instructions on enabling data virtualization

Locate the declaration of a field you want to virtualize

Add a custom attribute as shown below (C#):

using System;
using System.Reflection;

class YourClass
{
    [Obfuscation(Feature = "virtualization", Exclude = false)]
    bool yourField;
}

For Visual Basic .NET:

Imports System
Imports System.Reflection

Class YourClass

    <Obfuscation(Feature:="virtualization", Exclude:=False)>
    Dim yourField As Boolean
    
End Class

Note

Virtualization can significantly slow down the speed of code execution, so please use this feature wisely.

Note

Data virtualization can only be applied to the fields of the following types:
