INFO: Visual J# .NET Does Not Support Multidimensional SafeArrays (818448)
The information in this article applies to:
- Microsoft Visual J# .NET (2003)
- Microsoft Visual J# .NET (2002)
- Microsoft Common Language Runtime (included with the .NET Framework 1.1)
- Microsoft Common Language Runtime (included with the .NET Framework) 1.0
SUMMARYWhen you use multidimensional SafeArray data types in
Microsoft Visual J# .NET, you may receive unexpected results.
Visual
J# .NET does not support multidimensional SafeArrays and may only support one
dimensional SafeArray data types. If the SafeArray is multidimensional, the
marshaling may fail.MORE INFORMATIONIn Component Object Model (COM), an array is represented as
a SafeArray data type. A SafeArray is a self-describing array that contains any
type that can be placed in a VARIANT. SafeArray can have any number of
dimensions. Each of these dimensions can have distinct upper and lower bounds.
SafeArray is similar to the Microsoft Visual Basic 6.0 array type.
By
default, the behavior of the importer differs when it encounters SafeArray data
types. This behavior depends on whether you use the Type Library Importer
(Tlbimp.exe) or Microsoft Visual Studio .NET. When it refers a type library in
Visual Studio .NET, the IDE runs the equivalent of Tlbimp.exe with the /sysarray option. Every occurrence of a SafeArray is converted to a System.Array type. System.Array is the base class for all arrays in
Microsoft .NET
Framework arrays and is suffiently flexible to represent anything that a
SafeArray can represent. This includes multiple dimensions and custom bounds
for each dimension.
In Visual J# .NET, multidimensional SafeArrays do
not work even if you run Tlbimp.exe with the /sysarray option.REFERENCESFor more information about the SafeArray data type, visit
