Assembly.ReflectionOnlyLoad Method

Definition

Loads an assembly into the reflection-only context, where it can be examined but not executed.

Overloads

ReflectionOnlyLoad(Byte[])
Obsolete.

Loads the assembly from a common object file format (COFF)-based image containing an emitted assembly. The assembly is loaded into the reflection-only context of the caller's application domain.

ReflectionOnlyLoad(String)
Obsolete.

Loads an assembly into the reflection-only context, given its display name.

Caution

ReflectionOnly loading is not supported and throws PlatformNotSupportedException.

Loads the assembly from a common object file format (COFF)-based image containing an emitted assembly. The assembly is loaded into the reflection-only context of the caller's application domain.

Public Shared Function ReflectionOnlyLoad (rawAssembly As Byte()) As Assembly

Parameters

rawAssembly
Byte[]

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

Returns

The loaded assembly.

Attributes

Exceptions

rawAssembly is null.

rawAssembly is not a valid assembly for the currently loaded runtime.

rawAssembly cannot be loaded.

.NET Core and .NET 5+ only: In all cases.

Remarks

You cannot execute code from an assembly loaded into the reflection-only context. To execute code, the assembly must be loaded into the execution context as well, using the Load method.

The reflection-only context is no different from other contexts. Assemblies that are loaded into the context can be unloaded only by unloading the application domain.

Parameters

assemblyString
String

The display name of the assembly, as returned by the FullName property.

Returns

The loaded assembly.

Attributes

Exceptions

assemblyString is null.

assemblyString is an empty string ("").

assemblyString is not found.

assemblyString is found, but cannot be loaded.

assemblyString is not a valid assembly for the currently loaded runtime.

.NET Core and .NET 5+ only: In all cases.

Remarks

Dependencies are not automatically loaded into the reflection-only context.

You cannot execute code from an assembly loaded into the reflection-only context. To execute code, the assembly must be loaded into the execution context as well, using the Load method.
