AppDomain.ExecuteAssemblyByName Method (AssemblyName, String[])

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

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

member ExecuteAssemblyByName : 
        assemblyName:AssemblyName * 
        args:string[] -> int 


Type: System.Reflection.AssemblyName
An AssemblyName object representing the name of the assembly.
Type: System.String[]
Command-line arguments to pass when starting the process.

Return Value

Type: System.Int32
The value that is returned by the entry point of the assembly.


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.


assemblyName was compiled with a later version of the common language runtime than the version that is currently loaded.


The operation is attempted on an unloaded application domain.


The specified assembly has no entry point.

The ExecuteAssemblyByName method provides similar functionality to the ExecuteAssembly method, but specifies the assembly by display name or AssemblyName rather than by file location. Therefore, ExecuteAssemblyByName loads assemblies with the Load method rather than with the LoadFile method.

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.
