Calling a method using reflection

[jgd1234567]

Hi, i'm trying to build my own pager control. I have added a property called DataSourceID which allows me to access the ObjectDataSource on the page. However in my control i need to call the "SelectCountMethod" from the type "TypeName" specified by the object data source to return the number of rows. I understand the way to do this is to use reflection but i have no idea where to start.

Really appreciate it if someone could help. Thanks

//sample class
public class MyClass
{
    public int GetSomeInt(){ return 4; }
}

//to call a method of an unknown object
object mysteryObject = new MyClass();
string methodName = "GetSomeInt";
MethodInfo info = typeof(MyClass).GetMethod(methodName);
int returnValue = (int)info.Invoke(mysteryObject, null);

Slight correction to make it more dynamic:

object mysteryObject = new MyClass();
string methodName = "GetSomeInt";
MethodInfo info = typeof([b]mysteryObject.GetType()[/b]).GetMethod(methodName);
int returnValue = (int)info.Invoke(mysteryObject, null);

Slight other correction to get the code to compile.

MethodInfo info = mysteryObject.GetType().GetMethod(methodName);
