Assembly.LoadFile Method (String)

Loads the contents of an assembly file on the specified path.

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

public static Assembly LoadFile(
	string path


Type: System.String
The path of the file to load.

Return Value

Type: System.Reflection.Assembly
The loaded assembly.


The path parameter is null.


A file that was found could not be loaded.


The path parameter is an empty string ("") or does not exist.


path is not a valid assembly.


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

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.
