What's the best way to call a generic method when the type parameter isn't known at compile time, but instead is obtained dynamically at runtime? Consider the following sample code - inside the Example() method, what's the most concise way to invoke GenericMethod() using the type stored in the myType variable? public class Sample { ...
I have an abstract generic class BLL<T> where T : BusinessObject. I need to open an assembly that contains a set of concrete BLL classes, and return the tuples (businessObjectType, concreteBLLType) inside a Dictionary. There is the part of the method I could do until now, but I'm having problems to discover T. protected override Diction...

I'm currently working on a project where a section of the code looks like this: Select Case oReader.Name Case "NameExample1" Me.Elements.NameExample1.Value = oReader.ReadString .... Case "NameExampleN" Me.Elements.NameExampleN.Value = oReader.ReadString .... End Select It continues on for a while. The c...
So what I have right now is something like this: PropertyInfo[] info = obj.GetType().GetProperties(BindingFlags.Public); where obj is some object. The problem is some of the properties I want aren't in obj.GetType() they're in one of the base classes further up. If I stop the debugger and look at obj, the I have to dig through a few...
I know I can do this foreach (PropertyInfo property in myobject.GetType().GetProperties()) { if (property.DeclaringType.ToString() == myobject.GetType().ToString()) { // only have my object properties here // and not parent of my object properties } } But how can I just get the properties of myobject and...
I know that it is possible (in theory) to create a new type at run-time, but is it possible to modify a method body of an existing type at run-time? My plan (if I can get this to work) is to tag up methods with a custom attribute, and then at run-time search for methods with the attribute, and insert some of my own code into the method b...

I'm trying to find a way to automate some exception logging code to add to the stack information already available. Is there any way to use reflection to retrieve the values of all variables on the stack (locals and parameters) - I sincerely doubt the names of the variables are available, but in many cases it would be useful to see the ...
