Methodinfo.invoke problems

Question

Hi, I am having a problem with an exception being raised... Below is what I am trying to acheive..

I am trying to call a routine defined in the main class when a treeview item is selected.
I have stored the routine name under the treenode tag element and I am excuting the following code when it is selected.

private void treeView1_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)

{

if (e.Node.Tag == null)

{

}

else

{

Type theFunctionType = Type.GetType("XMLTree1.Form1");

Type[] paramTypes = new Type[0];

MethodInfo funcInfo = theFunctionType.GetMethod( e.Node.Tag.ToString(),paramTypes);

Object[] parameters = new Object[0];

object result = funcInfo.Invoke(theFunctionType,parameters);

 }

}

The problem is when the funcinfo.Invoke is executed I get the following exception...

"An unhandled exception of type 'System.Reflection.TargetException' occurred in mscorlib.dll

Additional information: Object does not match target type."

Can someone help please I am stuck to why this occurs..
Thanks
