I am looking for a way to dynamically load an assembly given the name of
the assembly. Is it appropriate to use the Assembly.Load() method and
specify the assembly name. I assume that this method will pick up the
private assemblies as well as those in the GAC. Is this correct?

Wally

PS. If this is the incorrect list to send this to, please alert me to
the correct one.

Here is something I use:

public void InvokeMethod(string sMethodName, object[] paramArray)
{
    object obj =3D null;
    object[] Parameters =3D null;
        =09
    try
    {
        //Get class type
        Type type =3D typeof([SomeNamespace]);

        // Create an instance of Routing in Memory
        obj =3D Activator.CreateInstance (type);
                =09
        //Get info for method
        MethodInfo mi =3D type.GetMethod(sMethodName);
        int numParams =3D mi.GetParameters().GetLength(0);
        Parameters =3D new object[numParams];
            =09
        if(numParams>0)
        {
            //only pass number of parameters each function needs
            for(int i=3D0;i<numParams;i++)
            {
                Parameters[i] =3D paramArray[i];
            }=09
                =09
            mi.Invoke(obj, Parameters);

        }
        else
        {
            //invoke method
            mi.Invoke(obj,null);
        }
    }
    catch(Exception e)
    {
        LogError(e.Message);
    }
}

This is useful if the assembly is already loaded. If not...
