dynamic class loading

[KC Eric]

Hi all,

If someone has compiled a dll for the some classes,
and I want to use the dll in another project, how can I know the class
available in that dll file?

Thanks!

Assembly a = Assembly.LoadFrom(<codebase of assembly>);
foreach( Type t in a.GetTypes() )
{
if( a.IsClass )
{
// Do stuff to class such as
object o = a.CreateInstance(t.FullName);
}
}

Obviously if you are interested in all types not just classes you can omit the if.

Thanks!

How about even the name of the dll file is not provided?

We only know the dll file is in a certain directory, say c:\temp, but the
name of dll is not known.

foreach( string fileName in Directory.GetFiles(<directory path>, "*.dll")
{
try
{
Assembly a = Assembly.LoadFrom(fileName);
// etc
}
catch( FileLoadException e)
{
// deal with the fact that some of the dlls may not be assemblies
}
}
