Assembly::Load Method (AssemblyName)
Loads an assembly given its AssemblyName.
Assembly: mscorlib (in mscorlib.dll)
assemblyRef is nullptr.
assemblyRef is not found.
A file that was found could not be loaded.
assemblyRef is not a valid assembly. -or-
Version 2.0 or later of the common language runtime is currently loaded and assemblyRef was compiled with a later version.
FileLoadException is thrown if assemblyRef specifies the full assembly name and the first assembly that matches the simple name has a different version, culture, or public key token. The loader does not continue probing for other assemblies that match the simple name.
Do not use an AssemblyName with only the CodeBase property set. The CodeBase property does not supply any elements of the assembly identity (such as name or version), so loading does not occur according to load-by-identity rules, as you would expect from the Load method. Instead, the assembly is loaded using load-from rules. For information about the disadvantages of using the load-from context, see the Assembly::LoadFrom method overload or Best Practices for Assembly Loading.
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 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 common object file format (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.
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.
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.
If both the AssemblyName::Name property and the AssemblyName::CodeBase property are set, the first attempt to load the assembly uses the display name (including version, culture, and so on, as returned by the Assembly::FullName property). If the file is not found, CodeBase is used to search for the assembly. If the assembly is found using CodeBase, the display name is matched against the assembly. If the match fails, a FileLoadException is thrown.
