Assembly.Load Method (Byte, Byte)
Loads the assembly with a Common Object File Format (COFF)-based image containing an emitted assembly.
[Visual Basic] Overloads Public Shared Function Load( _ ByVal rawAssembly() As Byte, _ ByVal rawSymbolStore() As Byte _ ) As Assembly [C#] public static Assembly Load( byte rawAssembly, byte rawSymbolStore ); [C++] public: static Assembly* Load( unsigned char rawAssembly __gc, unsigned char rawSymbolStore __gc ); [JScript] public static function Load( rawAssembly : Byte, rawSymbolStore : Byte ) : Assembly;
- An array of type byte that is a COFF-based image containing an emitted assembly.
- An array of type byte containing the raw bytes representing the symbols for the assembly.
The loaded assembly.
|ArgumentNullException||rawAssembly is a null reference (Nothing in Visual Basic).|
|SecurityException||The caller does not have the required permission.|
|BadImageFormatException||assemblyFile is not a valid assembly.|
The assembly is loaded into the domain of the caller, and the raw bytes representing the symbols for the assembly are also loaded.
The Load methods use the default load context, which records the assembly name and assembly instance information for the set of assemblies that is the transitive closure of the assemblies referenced by a managed application. The default load context applies to assemblies that are loaded with a Load method and that use a fully qualified assembly reference.
Whether certain permissions are granted or not granted to an assembly is based on evidence. The rules for assembly and security evidence merging are as follows:
- When you use a Load method with no Evidence parameter, the assembly is loaded with the evidence that the loader supplies.
- When you use a Load method with an Evidence parameter, pieces of evidence are merged. Pieces of evidence supplied as an argument to the Load method supersede pieces of evidence supplied by the loader.
- When you use a Load method with a Byte parameter to load a common object file format (COFF) image, evidence is combined. Zone, Url and Site are inherited from the calling assembly, and Hash and StrongName are taken from the COFF assembly.
- When you use a Load method with a Byte parameter and Evidence to load a common object file format (COFF) image, only the supplied evidence is used. Evidence of the calling assembly and evidence of the COFF image is ignored.
Reflecting on Managed Extensions for C++ executable files might throw a BadImageFormatException. This is most likely caused by C++ compiler stripping the relocation addresses or the .Reloc section from your executable file. To preserve the .reloc address for your C++ executable file, specify /fixed:no when you are linking.

.NET Framework Security:
- ReflectionPermission when invoked late-bound through mechanisms such as Type.InvokeMember. Associated enumeration: ReflectionPermissionFlag.MemberAccess.
- FileIOPermission for access to read from a file or directory, and for access to the information in the path itself. Associated enumerations: FileIOPermissionAccess.Read, FileIOPermissionAccess.PathDiscovery.
- WebPermission for reading a URI that does not begin with "file://".
- SecurityPermission to load an assembly with evidence. Associated enumeration: SecurityPermissionFlag.ControlEvidence.
