XPDictionary.GetDataStoreSchema(Assembly[]) Method

Gets the complete schema of a data store that corresponds to the persistent objects which are defined within the specified assemblies.

Namespace: DevExpress.Xpo.Metadata

Assembly: DevExpress.Xpo.v23.2.dll

NuGet Packages: DevExpress.Win.PivotGrid, DevExpress.Win.TreeMap, DevExpress.Xpo

NuGet Package: DevExpress.Xpo

Declaration

C#

public DBTable[] GetDataStoreSchema(
    params Assembly[] assemblies
)

VB.NET

Public Function GetDataStoreSchema(
    ParamArray assemblies As Assembly()
) As DBTable()

Parameters

Name	Type	Description
assemblies	Assembly[]	An array of assemblies which contain the persistent objects.

Returns

Type	Description
DBTable[]	An array of data tables of the DBTable type that correspond to the persistent objects which are defined in the assemblies within the assemblies array.

Remarks

The GetDataStoreSchema method enumerates all the types available in the specified assemblies. Some types may reference other assemblies. If CLR cannot load a referenced assembly, it throws the FileNotFoundException, FileLoadException, or BadImageFormatException. The GetDataStoreSchema method handles all exceptions and skips the problematic assembly without adding corresponding persistent classes to the dictionary.
