Guid Attribute
Class
System.Runtime.InteropServices.GuidAttribute
Applies To
Assembly, Class, Delegate, Enum, Interface, Struct
Constructor
New(guid)
guid (required; String)
The GUID to be assigned to the program element
Properties
Value (String)
Read-only. Value from the
guid constructor parameter.
Description
The <Guid> attribute assigns an explicit Globally Unique Identifier (GUID) to a
program element when an automatically generated GUID is undesirable. The
<Guid>
attribute is used for COM interop. A GUID can be generated by a utility named
guidgen.exe, which is included with Visual Studio.
Assigning a GUID to a program element, rather than allowing Visual Studio to do it
automatically, ensures that it remains constant over successive recompilations of the
source code. Because COM uses GUIDs to permanently identify program elements,
inadvertently changing a GUID may cause COM to fail to recognize a component.
Visual Studio automatically adds the
<Guid> attribute to each AssemblyInfo.vb file to
ensure that, should a type library be generated for a particular project, its library iden-
tifier (LibID) will remain unchanged when the project is recompiled.
