ObjectVersionCheckerIsEntityUpgradable Method

Checks whether entities of the specified class can be upgraded, and helps distinguish between backward and forward compatibility issues.

Namespace: Autodesk.Civil
Assembly: AeccDrainageDesignMgd (in AeccDrainageDesignMgd.dll) Version: 13.9.960.0
Syntax
Copy
public static bool IsEntityUpgradable(
	Database database,
	RXClass rxClass
)

Parameters

database  Database
The database containing the entities to check for upgrade capability.
rxClass  RXClass
The runtime class of the entity type to check.

Return Value

Boolean
True if entities of the specified class can be upgraded; otherwise, false. Returns true for backward compatibility scenarios where older version data can be upgraded. Returns false for forward compatibility scenarios where the data is from a newer version. When compatibility issues occur (E.g, "write/read/create" operations fail), use this method to determine the type of compatibility issue : True is indicating a backward compatibility issue - older version data that can be upgraded to benefit from new features / full capability in the current Civil 3D version. False is indicating a forward compatibility issue - newer version data is being processed by the current older Civil 3D version.
Exceptions
ExceptionCondition
ArgumentNullExceptionThrown when database or rxClass is null.
Remarks
This method is particularly useful for determining appropriate user messaging and available actions: - Backward compatibility: Users can upgrade objects to unlock full functionality, E.g, some UI may be read-only until upgrade - Forward compatibility: Users might need to consider using a newer Civil 3D version to work with these objects, otherwise, user operations on these objects might be limited.
