Assembly.LoadFile Method (String, Evidence)
Note: This API is now obsolete. The non-obsolete alternative is LoadFile(String).
Loads an assembly given its path, loading the assembly into the domain of the caller using the supplied evidence.
Assembly: mscorlib (in mscorlib.dll)
[ObsoleteAttribute("This method is obsolete and will be removed in a future release of the .NET Framework. Please use an overload of LoadFile which does not take an Evidence parameter. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information.")] [SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.ControlEvidence)] public static Assembly LoadFile( string path, Evidence securityEvidence )
Parameters
- path
- Type: System.String
The path of the assembly file.
- securityEvidence
- Type: System.Security.Policy.Evidence
Evidence for loading the assembly.
| Exception | Condition |
|---|---|
| ArgumentNullException |
The path parameter is null. |
| FileNotFoundException |
The path parameter is an empty string ("") or does not exist. |
| FileLoadException |
A file that was found could not be loaded. |
| BadImageFormatException |
path is not a valid assembly. -or- Version 2.0 or later of the common language runtime is currently loaded and path was compiled with a later version. |
| NotSupportedException |
securityEvidence is not null. By default, legacy CAS policy is not enabled in the .NET Framework version 4; when it is not enabled, securityEvidence must be null. |
Use the LoadFile method to load and examine assemblies that have the same identity, but are located in different paths. LoadFile does not load files into the LoadFrom context, and does not resolve dependencies using the load path, as the LoadFrom method does. LoadFile is useful in this limited scenario because LoadFrom cannot be used to load assemblies that have the same identities but different paths; it will load only the first such assembly.
