Assembly.Load Method (Byte[])


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

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

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

public static Assembly Load(
	byte[] rawAssembly


Type: System.Byte[]

A byte array that is a COFF-based image containing an emitted assembly.

Return Value

Type: System.Reflection.Assembly

The loaded assembly.

Exception Condition

rawAssembly is null.


rawAssembly is not a valid assembly.


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

The trust level of an assembly that is loaded by using this method is the same as the trust level of the calling assembly. To load an assembly from a byte array with the trust level of the application domain, use the Load(Byte[], Byte[], SecurityContextSource) method overload. For more information about the use of evidence with overloads of the Load method that take byte arrays, see the Load(Byte[], Byte[], Evidence) method overload.

Reflecting on C++ executable files might throw a BadImageFormatException. This is most likely caused by the 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 object with its own mapping.
