C# and VB.NET Expression Builder

The C# and VB.NET expression builders allow for the building and saving of an expression, to be used at scan time for the dynamic population of a metadata field.
By defining a metadata field as Expression (C# or vB.NET), you can use a subset of the C# or VB.NET programming languages to determine the ultimate value of the field.
The Expression Builder button appears when a metadata field of the correct type is selected. By clicking this button, you display the Expression Builder window, described below.

The Expression Builder window is split into three sections:
-The top expression section, in which the expression is built.
-The bottom left tree, in which you can select between the Metadata and IDCard MRZ.
-The bottom right list, in which the selected reference list is displayed.
By referring to the reference lists, you can build an expression to return a value; it is this value that will populate the metadata field to which this script is linked.
