IVariable The IVariable at the specified index.
Retrieves a variable declared in the graph by index.
Use this method to access a specific IVariable from the list of variables declared in the graph. This list does not include variable nodes that reference variables. The index is zero-based and reflects the order in which the variables were created. The index must be within the valid range of the variable list (see: VariableCount).
