dynamicly running methods.

[matt]

can i say store a method name in a database & then bring
it back & run it?

sort of like using the eval() in javascript?

i would prefer not to have a masively big switch
statement & instead store the relevent method name in the
database with the relevent record.

thanks in advance for any help.

Sure. Get the Type object (either using type(MyClass) or
<instance>.GetType()), and then call MethodInvoke(). Note that this is
slower than calling normally. You can get some speed increase by creating a
delegate of of a MethodInfo (use type.GetMethods to get the appropriate
method info), and then calling through that.

Check out
Type.GetMethod
method. This most likely does what you want to do. It takes a string, with
an overloaded parameter list for other options.
