R – Initparams from ASP.NET in silverlight 3.0

My team came up with a good solution. I'm not sure who deserves the credit but it's somewhere in google land. So far it works pretty good.

Essentially the solution comes down to using reflection to build a dynamic object based on this dynamic data. The function takes in a 2-dimensional array and turns it into a List object with properties that can be bound. We put this process in a WCF Service and it seems to do exactly what we need so far.

Here is some of the code that builds the object using Reflection

AppDomain myDomain = AppDomain.CurrentDomain;
            AssemblyName myAsmName = new AssemblyName("MyAssembly");

            AssemblyBuilder myAssembly = myDomain.DefineDynamicAssembly(myAsmName, AssemblyBuilderAccess.Run);
            ModuleBuilder myModule = myAssembly.DefineDynamicModule(myAsmName.Name);

            TypeBuilder myType = myModule.DefineType("DataSource", TypeAttributes.Public);

            string columnName = "whatever";

            for (int j = 0; j <= array.GetUpperBound(1); j++)
            {

                Type properyType = typeof(T);
                FieldBuilder exField = myType.DefineField("_" + "columnName" + counter, properyType, FieldAttributes.Private);

                  //The following line is where I’m passing columnName + counter and getting errors with some strings but not others.
                PropertyBuilder exProperty = myType.DefineProperty(columnName + counter.ToString(), PropertyAttributes.None, properyType, Type.EmptyTypes);
                //Get

                MethodBuilder exGetMethod = myType.DefineMethod("get_" + "columnName" + counter, MethodAttributes.Public, properyType, Type.EmptyTypes); ILGenerator getIlgen = exGetMethod.GetILGenerator();
                //IL for a simple getter:
                //ldarg.0 
                //ldfld int32 SilverlightClassLibrary1.Class1::_Age
                //ret 

                getIlgen.Emit(OpCodes.Ldarg_0);
                getIlgen.Emit(OpCodes.Ldfld, exField);

                getIlgen.Emit(OpCodes.Ret);
                exProperty.SetGetMethod(exGetMethod);

                //Set

                MethodBuilder exSetMethod = myType.DefineMethod("set_" + "columnName" + counter, MethodAttributes.Public, null, new Type[] { properyType }); ILGenerator setIlgen = exSetMethod.GetILGenerator();
                //IL for a simple setter:
                //ldarg.0 
                //ldarg.1 
                //stfld int32 SilverlightClassLibrary1.Class1::_Age
                //ret 

                setIlgen.Emit(OpCodes.Ldarg_0);
                setIlgen.Emit(OpCodes.Ldarg_1);

                setIlgen.Emit(OpCodes.Stfld, exField); setIlgen.Emit(OpCodes.Ret);
                exProperty.SetSetMethod(exSetMethod);

                counter++;

            }
            finished = myType.CreateType();
