C# 2.0 Support

  Reflector won't do the translation that you want for the anonymous type. In the IL the anonymous type is constructed using a constructor argument.

  var foo = new  {A = "jajaj2"};
  

  is generated as a call

  AnonymousType0<string> type = new AnonymousType0<string>("jajaj2");
  

  so you'd have to do analysis to determine that the constructor argument is referring to the property.
  
  Reflector recognises the anonymous types, causing it to emit the 3.0 syntax, by looking for the prefix "<>f__" on the type name. I managed to get the latter form of the construction by using ildasm, removing the prefix and then using ilasm to reconstruct the assembly but that trick doesn't get you all the way to what you want.

  Well, Clive, thank you very much for the answer!
  
  Оne more question.
  
  How to manage extension methods? I want Reflector to generate old-style call:

  IEnumerable<string> namesStartingWithA = Enumerable.Where(
      names, delegate(string n) { return n.StartsWith("A"); });
  

  instead of 3.0 syntax:

  var namesStartingWithA = names.Where(name => name.StartsWith("A"));
  

  
  May be, it's worth to add two different items (C# 2.0 and C# 3.0) insted of the only one (C#) in language choise combobox?

  I think you're looking for the View/Options/Disassembler/Optimization combobox.
  
  In Reflector 5.1.5, setting this optimization level to 3.5 makes some code appear as
  

     string[] names = new string[] { "a" };
      IEnumerable<string> namesStartingWithA = from n in names
          where n.StartsWith("A")
          select n;
  

  
  Changing the level to .NET 2.0 gives
  

     IEnumerable<string> namesStartingWithA = new string[] { "a" }.Where<string>(delegate (string n) {
          return n.StartsWith("A");

  Here we rid of (I'm not sure how it should be in English) type inference and lambdas, but extension method (Where) still remain. I need this transform:

  IEnumerable<string> namesStartingWithA = Enumerable.Where<string>(new string[] { "a" }, delegate (string n) { ...

  Hi all,
  I am creating Window Application using c#.net.
  I want to show message box with error icon on button click.
  For showing message box the code is
  
  MessageBox.Show("Error");
  
  But What to do for including error icon?
