Convert.ChangeT ype with reference type ie Int32& - can I get the base type?

[phancey]

I am trying to invoke a web service method dynamically. I have created
a generic function that takes a method name, string of parameters and
calls the web method using System.Reflecti on:

MethodInfo mi = proxyInstance.G etType().GetMet hod(methodName) ;
object[] paramsArray = (object[])methodParams.T oArray(typeof(o bject));
object result = mi.Invoke(proxy Instance, paramsArray);

where methodParams is an array of parameters where the value stripped
from the string has been converted into the relevant system.type using:
methodParams[i] = Convert.ChangeT ype(methodParam s[i],
(mi.GetParamete rs())[i].ParameterType) ;

This works fine unless the web method uses reference parameters.
Reference parameters themselves are not a problem if I didn't have to
use the Convert.ChangeT ype function. Convert.ChangeT ype does not work
with type System.Int32&.

Ref strings are fine because I can just avoid using the function
altogether but is there a way I can get the base type of a ByRef
parameter? I had a look at the structure of ParameterType but couldn't
find anywhere where System.Int32& could be interpreted as System.Int32

I can use this:
if (pi[i].ParameterType == System.Type.Get Type("System.In t32&"))
paramValue = Convert.ChangeT ype(paramValue,
System.Type.Get Type("System.In t32") );

but this requires me to code for each specific ref type. Is there a
simple property that allows me to get the right type?

thanks

Type.GetElement Type()
