Question

Is it possible to get access to a private static field inside a static class, using the VS2010 Unit Test class PrivateObject ?

Let say i have the following class:

public static class foo
{
    private static bar;
}

Can i use PrivateObject to create a copy of foo, and then get the bar field?

Answer 1

The property value can be retreived using reflection. This will require the use of Type.GetField Method (String, BindingFlags) and the FieldInfo.GetValue Method

string propertyName = "bar";
FieldInfo fieldInfo = typeof(foo).GetField(propertyName, BindingFlags.NonPublic | BindingFlags.Static);
object fieldValue = fieldInfo.GetValue(null);
