Assembly.Load Method (Byte[])

Loads the assembly with a common object file format (COFF)-based image containing an emitted assembly. The assembly is loaded into the domain of the caller.

Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

public static Assembly Load (
	byte[] rawAssembly
)
public static Assembly Load (
	byte[] rawAssembly
)
public static function Load (
	rawAssembly : byte[]
) : Assembly
Not applicable.

Parameters

rawAssembly

An array of type byte that is a COFF-based image containing an emitted assembly.

Return Value

The loaded assembly.

Exception typeCondition

ArgumentNullException

rawAssembly is a null reference (Nothing in Visual Basic).

BadImageFormatException

rawAssembly is not a valid assembly.

-or-

Version 2.0 or later of the common language runtime is currently loaded and rawAssembly was compiled with a later version.

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 overload with a Byte[] parameter to load a COFF image, evidence is inherited from the calling assembly. This applies to the .NET Framework version 1.1 Service Pack 1 (SP1) and subsequent releases.

    NoteNote:

    In the .NET Framework version 1.0 and in version 1.1 without SP1, when you use a Load method overload with a Byte[] parameter to load a 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 COFF image, only the supplied evidence is used. Evidence of the calling assembly and evidence of the COFF image is ignored.

Reflecting on 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.

Note that this method overload always creates a new assembly with its own mapping.
