I have a class:

```
public abstract class SendAgencyFileComponent : ISendAgencyFileComponent
{
    public AgencyOutput agencyOutput;
    public TDXDataTypes.DB.Entity client;
    public TDXDataTypes.DB.Entity agency;

    public SendAgencyFileComponent(AgencyOutput agencyOutput, TDXDataTypes.DB.Entity client, TDXDataTypes.DB.Entity agency)
    {
        this.agencyOutput = agencyOutput;
        this.client = client;
        this.agency = agency;
    }
}

```

I have a number of classes that inherit from this class, that reside in various DLLs (including the one this is being called from, but in a different location). I need to be able to instantiate an instance of this class from the DLL location and class name. Currently I am using:

```
System.Reflection.Assembly assembly = 
   System.Reflection.Assembly.LoadFrom(
   "C:\\Program Files\\RMIS\\" + format.AssemblyName + ".dll");

return assembly.CreateInstance(
   format.ClassName, 
   true, 
   System.Reflection.BindingFlags.CreateInstance, 
   null, 
   new Object[] { agencyOutput, client, agency }, 
   System.Globalization.CultureInfo.CurrentCulture, 
   null
   ) as DotNet_WS_Components.ISendAgencyFileComponent;

```

But I keep getting the error:

Constructor on type 'TDXDataTypes.DotNet\_WS\_Components.InternationalAgencyFileOut' not found.

I'm sure my arguments match the constructor perfectly, and when loading the class from the same assembly using Activator.CreateInstance, it works fine:

```
System.Runtime.Remoting.ObjectHandle sendFilehandle = 
   Activator.CreateInstance(
       format.AssemblyName, 
       format.ClassName, 
       true, 
       System.Reflection.BindingFlags.CreateInstance, 
       null,
       new Object[] { agencyOutput, client, agency }, 
       System.Globalization.CultureInfo.CurrentCulture, 
       null, 
       null);

       return (TDXDataTypes.DotNet_WS_Components.ISendAgencyFileComponent)sendFilehandle.Unwrap();

```

The particular example I'm working on at the moment is:

```

Webservice
-> calls TDXDataTypes dll method through referenced DLL
-> calls TDXDataTypes dll class (above) using reflection from a different folder

```
