    <p>I've ran into a problem and wondered if there's simple way of solving it.</p> <p>Here I have a XML template, defining some properties and their values.</p> <pre><code>&lt;Properties&gt; &lt;Property name="ID"&gt;10000&lt;/Property&gt; &lt;Property name="Name"&gt; &lt;SubProperty name="FirstName"&gt;Foo&lt;/SubProperty&gt; &lt;SubProperty name="LastName"&gt;Bar&lt;/SubProperty &gt; &lt;/Property&gt; &lt;/Properties&gt; </code></pre> <p>All I what is to extract the Properties/subProperties defined in the template to generate a new XML file, with all values attached, something like</p> <pre><code>&lt;Items&gt; &lt;ID&gt;10000&lt;/ID&gt; &lt;Name&gt; &lt;FirstName&gt;Foo&lt;/FirstName&gt; &lt;LastName&gt;Bar&lt;/LastName&gt; &lt;/Name&gt; &lt;/Items&gt; </code></pre> <p>Since I don't know the content of the template in design time, I tried to load it and created a List class use LINQ, but cannot get the result above when serialize it directly. So instead of create a List class I created a dynamic object using Reflection.Emit and then serialize the object to XML. </p> <hr> <pre><code>private static readonly XDocument doc = XDocument.Load("Template.xml"); static void Main(string[] args) { var newType = CreateDynamicType(); var newObject = Activator.CreateInstance(newType); var properties = newType.GetProperties(); foreach (var property in properties) { // assign values } SerializeToXml(newObject); } private static Type CreateDynamicType() { AssemblyName assemblyName = new AssemblyName() { Name = "DynamicTypeAdapter" }; AssemblyBuilder assembly = Thread.GetDomain().DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.Run); ModuleBuilder module = assembly.DefineDynamicModule(assembly.GetName().Name, false); TypeBuilder type = module.DefineType("Items", TypeAttributes.Public | TypeAttributes.Class); foreach (var p in doc.Descendants("Property")) { string pName = p.Attribute("name").Value; TypeBuilder subType = module.DefineType(pName, TypeAttributes.Public | TypeAttributes.Class); foreach (var sp in p.Descendants("SubProperty")) { CreateDynamicProperty(subType, sp.Attribute("name").Value, typeof(string)); } var propertyType = subType.CreateType(); CreateDynamicProperty(type, pName, propertyType); } return type.CreateType(); } private static void CreateDynamicProperty(TypeBuilder typeBuilder, string propertyName, Type propertyType) { PropertyBuilder property = typeBuilder.DefineProperty(propertyName, PropertyAttributes.None, propertyType, new Type[] { typeof(string) }); FieldBuilder field = typeBuilder.DefineField("_" + propertyName, propertyType, FieldAttributes.Private); MethodAttributes GetSetAttributes = MethodAttributes.Public | MethodAttributes.HideBySig; MethodBuilder getMethod = typeBuilder.DefineMethod("get_value", GetSetAttributes, propertyType, Type.EmptyTypes); ILGenerator getIL = getMethod.GetILGenerator(); getIL.Emit(OpCodes.Ldarg_0); getIL.Emit(OpCodes.Ldfld, field); getIL.Emit(OpCodes.Ret); MethodBuilder setMethod = typeBuilder.DefineMethod("set_value", GetSetAttributes, null, new Type[] { typeof(string) }); ILGenerator setIL = setMethod.GetILGenerator(); setIL.Emit(OpCodes.Ldarg_0); setIL.Emit(OpCodes.Ldarg_1); setIL.Emit(OpCodes.Stfld, field); setIL.Emit(OpCodes.Ret); property.SetGetMethod(getMethod); property.SetSetMethod(setMethod); } </code></pre> <hr> <p>It works fine but is there any simple way of doing this? Any comment is appreciated. Thanks</p>

    1. COYou've presented a problem, and some sample XML, but I am still having a hard time understanding what your code is actually doing. Could you post an example of the code you currently have?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
