public void DefineUnmanagedResource(
	byte[] resource


Type: System.Byte[]

An opaque BLOB that represents an unmanaged resource

Exception Condition

An unmanaged resource has already been defined in the module's assembly.


resource is null.

An assembly can be associated with only one unmanaged resource. This means that calling DefineVersionInfoResource or DefineUnmanagedResource after either one of the methods was called previously throws ArgumentException. Multiple unmanaged resources need to be merged with a tool such as the Microsoft ResMerge utility (not supplied with the common language runtime).
