The DynExpr class represents expressions that can be re-evaluated dynamically and variables that can receive assignment or be re-evaluated dynamically. These expressions are used to access the value of a dynamically created field.

Because dynamic expressions are compiled and bound at runtime, it is necessary to track the scope of variables referenced in order to evaluate the symbols in the expression. The scope for the evaluation is included in the representation of the dynamic expression.

You create DynExpr objects by invoking the CreateDynExpr method (see CreateDynExpr Method) of the Scope class. For examples of using dynamic expressions, see the Programming Guide.
