• Determining if a .NET type is dynamic (created using Reflection.Emit)

  - by Diego Mijelshon

  While the .NET 4 framework provides the Assembly.IsDynamic method, that's not the case with .NET 2.0/3.5. The use case is simple: for logging purposes, I want to determine the underlying type name of an entity that might be wrapped by a dynamic proxy without having any references to NHibernate or Castle (which know about the proxy) For example, I…

  Hi guys! For my small hobby project I need to emit machine code from C++ program in runtime. I have base address 0xDEADBEEF and want to write something like this: Assembler a((void*)0xDEADBEEF); a.Emit() << Push(Reg::Eax) << Push(Reg::Ebx) << Jmp(0xFEFEFEFE); Inline assembler isn't my choice because generated…

• CouchDB emit with lookup key that is array, such that order of array elements are ignored.

  - by MatternPatching

  When indexing a couchdb view, you can emit an array as the key such as: emit(["one", "two", "three"], doc); I appreciate the fact that when searching the view, the order is important, but sometimes I would like the view to ignore it. I have thought of a couple of options. 1. By convention, just emit the contents in alphabetical order,…

• How does LinqPad support WCF Data Services?

  - by user341127

  LinqPad supports WCF Data Services. If you assign an URL, such as http://services.odata.org/Northwind/Northwind.svc/. It will list all available data objects and you can query them. I guess LinqPad generates all available data classes at run time by reflection.Emit. I am wondering who can show me to how to do so. Or maybe someone…

  How can I generate types like these using the System.Reflection.Emit libraries: public class Test<T> {} public class Test<T1, T2> {} When I call ModuleBuilder.DefineType(string) with the second type declaration, I get an exception because there is already another type in the module with the same name (I've already…

  I am trying to use Reflection.Emit to generate a wrapper class in a dynamic assembly. Automatic wrapper generation is part of a new open-source library I'm writing called "GoInterfaces". The wrapper class implements IEnumerable<string> and wraps List<string>. In C# terms, all it does is this: …

  System.Array serves as the base class for all arrays in the Common Language Runtime (CLR). According to this article, For each concrete array type, [the] runtime adds three special methods: Get/Set/Address. and indeed if I disassemble this C# code, int[,] x = new int[1024,1024]; x[0,0] = 1; x[1,1] =…

• IL short-form instructions aren't short?

  - by Alix

  Hi. I was looking at the IL code of a valid method with Reflector and I've run into this: L_00a5: leave.s L_0103 Instructions with the suffix .s are supposed to take an int8 operand, and sure enough this is should be the case with Leave_S as well. However, 0x0103 is 259, which exceeds the capacity of an…

• Populating and Using Dynamic Classes in C#/.NET 4.0

  In our application we're considering using dynamically generated classes to hold a lot of our data. The reason for doing this is that we have customers with tables that have different structures. So you could have a customer table called "DOG" (just making this up) that contains the columns "DOGID",…

  I have a library of dubious origins which is identified by file as a 32 bit executable. However, when I try to dlopen it on a 32 bit CentOS 4.4 machine, dlopen terminates with SIGFPE. Surely if there was something wrong with the format of the binary then dlopen should be handling an error? …
