Assembly.ReflectionOnlyLoad Method

Definition

Namespace:

System.Reflection

Assembly:

System.Runtime.dll

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.

ReflectionOnlyLoad(Byte[])

Source:

Assembly.cs

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.

 static System::Reflection::Assembly ^ ReflectionOnlyLoad(cli::array <System::Byte> ^ rawAssembly);

[<System.Obsolete("ReflectionOnly loading is not supported and throws PlatformNotSupportedException.", DiagnosticId="SYSLIB0018", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
static member ReflectionOnlyLoad : byte[] -> System.Reflection.Assembly

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

Assembly

The loaded assembly.

Attributes

ObsoleteAttribute

Exceptions

ArgumentNullException

rawAssembly is null.

BadImageFormatException

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

FileLoadException

rawAssembly cannot be loaded.

PlatformNotSupportedException

.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.

ReflectionOnlyLoad(String)

Source:

Assembly.cs

Caution

ReflectionOnly loading is not supported and throws PlatformNotSupportedException.

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

public:
 static System::Reflection::Assembly ^ ReflectionOnlyLoad(System::String ^ assemblyString);

[System.Obsolete("ReflectionOnly loading is not supported and throws PlatformNotSupportedException.", DiagnosticId="SYSLIB0018", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
public static System.Reflection.Assembly ReflectionOnlyLoad (string assemblyString);

[<System.Obsolete("ReflectionOnly loading is not supported and throws PlatformNotSupportedException.", DiagnosticId="SYSLIB0018", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
static member ReflectionOnlyLoad : string -> System.Reflection.Assembly

Public Shared Function ReflectionOnlyLoad (assemblyString As String) As Assembly

Parameters

assemblyString

String

Returns

Assembly

The loaded assembly.

Attributes

ObsoleteAttribute

Exceptions

ArgumentNullException

assemblyString is null.

ArgumentException

assemblyString is an empty string ("").

FileNotFoundException

assemblyString is not found.

FileLoadException

assemblyString is found, but cannot be loaded.

BadImageFormatException

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

PlatformNotSupportedException

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.

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.
