Message-ID: <1998A959-9D6F-4677-98DB-BDBF39A6308D@upplopp.se> I stand corrected. I was almost certain I couldn't edit it. *crawls back into his corner* The information I'm referring to is mostly IronRuby on Mono stuff. It refers to repositories that don't exist and build processes that don't work. I'm currently working with Wayne from rvm to get IronRuby on RVM and it's been a bit of a head scratcher. Hopefully we'll get it working soon. I'll update the wiki with new mono build info.

I?ve adjusted the code to support a number of types, incl int, bool and float. However the CLR crashes when-ever I assign a value to a non-string property, e.g float or int. ?The runtime has encountered a fatal error. The address of the error was at 0x5935788d, on thread 0x1adc. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.? Any assistance would be deeply appreciated.

I?ve adjusted the code to support a number of types, incl int, bool and float. However the CLR crashes when-ever I assign a value to a non-string property, e.g float or int. ?The runtime has encountered a fatal error. The address of the error was at 0x5935788d, on thread 0x1adc. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.? Any assistance would be deeply appreciated. In essence, instead of using typeof(string) inside the TypeGenerator.Generate method, i use e.g; typeof(int) or typeof(float) This is my current code: C#: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; using System.Reflection.Emit; namespace GenerateType { public class TypeGenerator { public delegate object GetPropertyDelegate(string propertyName); public delegate object SetPropertyDelegate(string propertyName, object value); public static Type Generate(string className, Dictionary> properties) { AssemblyName asmName = new AssemblyName("BindingTypes"); AssemblyBuilder asmBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(asmName, AssemblyBuilderAccess.Run); ModuleBuilder modBuilder = asmBuilder.DefineDynamicModule("Types"); TypeBuilder typeBuilder = modBuilder.DefineType(className, TypeAttributes.Public | TypeAttributes.Class | TypeAttributes.AutoClass | TypeAttributes.AnsiClass | TypeAttributes.BeforeFieldInit | TypeAttributes.AutoLayout); FieldBuilder getFieldBuilder = typeBuilder.DefineField("OnGet", typeof(GetPropertyDelegate), FieldAttributes.Public); FieldBuilder setFieldBuilder = typeBuilder.DefineField("OnSet", typeof(SetPropertyDelegate), FieldAttributes.Public); MethodAttributes getSetAttr = MethodAttributes.Public | MethodAttributes.SpecialName | MethodAttributes.HideBySig; Type type = null; foreach (string s in properties.Keys) { type = null; switch (s) { case "float": type = typeof(float); break; case "int": type = typeof(int); break; case "string": type = typeof(string); break; case "bool": type = typeof(bool); break; //case "dynamic": // type = dynamic; } if (type != null) { GenerateProperties(properties[s], type, typeBuilder, getSetAttr, getFieldBuilder, setFieldBuilder); } } return typeBuilder.CreateType(); } public static void GenerateProperties(List properties, Type type, TypeBuilder typeBuilder, MethodAttributes getSetAttr, FieldBuilder getFieldBuilder, FieldBuilder setFieldBuilder) { foreach (string propertyName in properties) { PropertyBuilder propBuilder = typeBuilder.DefineProperty(propertyName, PropertyAttributes.None, typeof(object), new Type[] {}); MethodBuilder getter = typeBuilder.DefineMethod("get_" + propertyName, getSetAttr, type, Type.EmptyTypes); ILGenerator ilGen = getter.GetILGenerator(); ilGen.Emit(OpCodes.Ldarg_0); ilGen.Emit(OpCodes.Ldfld, getFieldBuilder); ilGen.Emit(OpCodes.Ldstr, propertyName); ilGen.Emit(OpCodes.Callvirt, typeof(GetPropertyDelegate).GetMethod("Invoke")); ilGen.Emit(OpCodes.Ret); // Define the "set" accessor method for CustomerName.

Rob, it's best to avoid depending on IronRuby built-in types in your .NET API unless you absolutely need to, as well as always having your .NET API's arguments be interface types, so both Ruby and .NET can call into them. If you did this: // C# public class MyClass { public void Foo(IDictionary args) {} } You can still call it from Ruby: my_class.foo :limit => 5, :offset => 10 As for indexing, you can copy the provided Hash into a Dictionary to provide string-based indexing: void Foo(IDictionary args) { var dict = new Dictionary(); foreach (DictionaryEntry a in args) dict[a.Key.ToString()] = a.Value; var limit = dict["limit"]; var offset = dict["offset"]; // do your stuff } Another option (which I like more) is to write a Ruby wrapper around it to convert the keys to CLR strings: require 'MyClass' # load above assembly class MyClass # monkey-patch above .NET class alias :orig_foo :foo def foo(args) orig_foo args.inject({}){|i,(j,k)| i[j.to_clr_string] = k; i } end end Then you wouldn't have to do the conversion in C#: void Foo(IDictionary dict) { var limit = dict["limit"]; var offset = dict["offset"]; // do your stuff } I like the latter option best because you do what Ruby needs in Ruby; your .NET code assumes it's getting a CLR string rather than forcing it to be. However, it's not ideal as you have to copy the dictionary in both cases, but for an argument hash it's very unlikely to become an issue. You'll notice that if you a .NET method that accepts a string, you can pass it a Ruby symbol; we do the conversion between Ruby symbols and .NET strings. However, we don't do conversions between generic arguments, especially with a Ruby Hash, were they keys could be different types. But we could convert a Hash to a statically typed Dictionary if all they keys are the same type; if you feel strongly about this please open a bug. ~Jimmy -------------- next part -------------- An HTML attachment was scrubbed...

I don't feel strongly about it so I'll just put in a little helper function to my .NET project to convert a Hash to a Dictionary.
