AppDomain.ExecuteAssemblyByName Method (AssemblyName, Evidence, String[])

Note: This method is new in the .NET Framework version 2.0.

Executes the assembly given an AssemblyName, using the specified evidence and arguments.

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

public int ExecuteAssemblyByName (
	AssemblyName assemblyName,
	Evidence assemblySecurity,
	params string[] args
public int ExecuteAssemblyByName (
	AssemblyName assemblyName, 
	Evidence assemblySecurity, 
	String[] args
public function ExecuteAssemblyByName (
	assemblyName : AssemblyName, 
	assemblySecurity : Evidence, 
	... args : String[]
) : int



An AssemblyName object representing the name of the assembly.


Evidence for loading the assembly.


Command-line arguments to pass when starting the process.

Return Value

The value returned by the entry point of the assembly.

Exception typeCondition


The assembly specified by assemblyName is not found.


The assembly specified by assemblyName was found, but could not be loaded.


The assembly specified by assemblyName is not a valid assembly.


Operations are attempted on an unloaded application domain.

The ExecuteAssemblyByName method provides similar functionality to the ExecuteAssembly method, but specifies the assembly by display name or AssemblyName rather than by file location.

The assembly begins executing at the entry point specified in the .NET Framework header.

This method does not create a new process or application domain, and it does not execute the entry point method on a new thread.


When you use the ExecuteAssemblyByName method with an Evidence parameter, pieces of evidence are merged. Pieces of evidence supplied as an argument to the ExecuteAssemblyByName method supersede pieces of evidence supplied by the loader.
