XPDictionary.CollectClassInfos(Assembly[]) Method

Obtains the metadata information for all the persistent objects that are defined in the specified assemblies.

Namespace: DevExpress.Xpo.Metadata

Assembly: DevExpress.Xpo.v21.1.dll

NuGet Package: DevExpress.Xpo

Declaration

C#

public XPClassInfo[] CollectClassInfos(
    params Assembly[] assemblies
)

VB.NET

Public Function CollectClassInfos(
    ParamArray assemblies As Assembly()
) As XPClassInfo()

Parameters

Name	Type	Description
assemblies	Assembly[]	An array of assemblies which contain the persistent objects whose metadata information is collected.

Returns

Type	Description
XPClassInfo[]	An array of the XPClassInfos for the persistent objects that are defined in the assemblies within the assemblies array.

Remarks

The CollectClassInfos 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 CollectClassInfos method handles all exceptions and skips the problematic assembly without adding corresponding persistent classes to the dictionary.
