Now I get a value in the variable currentMode. When I view this variable in the debugger it shows
System.Web.Configuration.AuthenticationMode.Forms

But I don't know how to use this in the IF statement.

For example,

if (currentMode   .... // I need to determine that it is Forms)
{
    // take action
}

How do I compare the value in currentMode?

UPDATE. Figured the answer. It is:

if (currentMode.Equals(System.Web.Configuration.AuthenticationMode.Forms))
....
