解决方案：

Solution:

好了，基本上我所。做的是为了创建一个动态对象重用从主题的MyTypeBuilder类（有一些改动）以下，且增加了一个方法从它那里得到一个IList

Ok, basically what I've done was reusing the MyTypeBuilder class (with some adaptations) from the topic below in order to create a dynamic object and added a method to get an IList from it.

public class MyObjectBuilder
{
    public Type objType { get; set; }

    public MyObjectBuilder()
    {
        this.objType = null;
    }

    public object CreateNewObject(List<Field> Fields)
    {
        this.objType = CompileResultType(Fields);
        var myObject = Activator.CreateInstance(this.objType);

        return myObject;
    }

    public IList getObjectList()
    {
        Type listType = typeof(List<>).MakeGenericType(this.objType);

        return (IList)Activator.CreateInstance(listType);
    }

    public static MethodInfo GetCompareToMethod(object genericInstance, string sortExpression)
    {
        Type genericType = genericInstance.GetType();
        object sortExpressionValue = genericType.GetProperty(sortExpression).GetValue(genericInstance, null);
        Type sortExpressionType = sortExpressionValue.GetType();
        MethodInfo compareToMethodOfSortExpressionType = sortExpressionType.GetMethod("CompareTo", new Type[] { sortExpressionType });

        return compareToMethodOfSortExpressionType;
    }

    public static Type CompileResultType(List<Field> Fields)
    {
        TypeBuilder tb = GetTypeBuilder();
        ConstructorBuilder constructor = tb.DefineDefaultConstructor(MethodAttributes.Public | MethodAttributes.SpecialName | MethodAttributes.RTSpecialName);

        // NOTE: assuming your list contains Field objects with fields FieldName(string) and FieldType(Type)
        foreach (var field in Fields)
            CreateProperty(tb, field.FieldName, field.FieldType);

        Type objectType = tb.CreateType();
        return objectType;
    }

    private static TypeBuilder GetTypeBuilder()
    {
        var typeSignature = "MyDynamicType";
        var an = new AssemblyName(typeSignature);
        AssemblyBuilder assemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(an, AssemblyBuilderAccess.Run);
        ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("MainModule");
        TypeBuilder tb = moduleBuilder.DefineType(typeSignature
                            , TypeAttributes.Public |
                            TypeAttributes.Class |
                            TypeAttributes.AutoClass |
                            TypeAttributes.AnsiClass |
                            TypeAttributes.BeforeFieldInit |
                            TypeAttributes.AutoLayout
                            , null);
        return tb;
    }

    private static void CreateProperty(TypeBuilder tb, string propertyName, Type propertyType)
    {
        FieldBuilder fieldBuilder = tb.DefineField("_" + propertyName, propertyType, FieldAttributes.Private);

        PropertyBuilder propertyBuilder = tb.DefineProperty(propertyName, PropertyAttributes.HasDefault, propertyType, null);
        MethodBuilder getPropMthdBldr = tb.DefineMethod("get_" + propertyName, MethodAttributes.Public | MethodAttributes.SpecialName | MethodAttributes.HideBySig, propertyType, Type.EmptyTypes);
        ILGenerator getIl = getPropMthdBldr.GetILGenerator();

        getIl.Emit(OpCodes.Ldarg_0);
        getIl.Emit(OpCodes.Ldfld, fieldBuilder);
        getIl.Emit(OpCodes.Ret);

        MethodBuilder setPropMthdBldr =
            tb.DefineMethod("set_" + propertyName,
              MethodAttributes.Public |
              MethodAttributes.SpecialName |
              MethodAttributes.HideBySig,
              null, new[] { propertyType });

        ILGenerator setIl = setPropMthdBldr.GetILGenerator();
        Label modifyProperty = setIl.DefineLabel();
        Label exitSet = setIl.DefineLabel();

        setIl.MarkLabel(modifyProperty);
        setIl.Emit(OpCodes.Ldarg_0);
        setIl.Emit(OpCodes.Ldarg_1);
        setIl.Emit(OpCodes.Stfld, fieldBuilder);

        setIl.Emit(OpCodes.Nop);
        setIl.MarkLabel(exitSet);
        setIl.Emit(OpCodes.Ret);

        propertyBuilder.SetGetMethod(getPropMthdBldr);
        propertyBuilder.SetSetMethod(setPropMthdBldr);
    }
}

另外，我用了一个Field类像这样有在某一特定领域

Also, I used a Field class like so to have information on a particular Field

public class Field
{
   public string FieldName;
   public Type FieldType;
}

最后，我发现这个方法的地方，可以让一个人的值设置为会员：

Finally, I found this method somewhere that allows a person to set the value to a Member:

public static void SetMemberValue(MemberInfo member, object target, object value)
{
   switch (member.MemberType)
   {
       case MemberTypes.Field:
           ((FieldInfo)member).SetValue(target, value);
           break;
       case MemberTypes.Property:
           ((PropertyInfo)member).SetValue(target, value, null);
           break;
       default:
           throw new ArgumentException("MemberInfo must be if type FieldInfo or PropertyInfo", "member");
   }
}

之后，我做了以下创建一个动态对象并插入一个属性就可以了：

Afterwards, I did the following to create a dynamic object and insert a property on it:

//Creating a List of Fields (string FieldName, Type FieldType) 
List<Field> Fields = new List<Field>();
Fields.Add(new Field { FieldName = "TestName", FieldType = typeof(string) });

//MyObjectBuilder Class
MyObjectBuilder o = new MyObjectBuilder();

//Creating a new object dynamically
object newObj = o.CreateNewObject(Fields);
IList objList = o.getObjectList();

Type t = newObj.GetType();
object instance = Activator.CreateInstance(t);

PropertyInfo[] props = instance.GetType().GetProperties();

int instancePropsCount = props.Count();

for (int i = 0; i < instancePropsCount; ++i)
{
   string fieldName = props[i].Name;
   MemberInfo[] mInfo = null;
   PropertyInfo pInfo = newObj.GetType().GetProperty(fieldName);

   if (pInfo != null)
   {
       var value = pInfo.GetValue(newObj, null);
       mInfo = t.GetMember(fieldName);

       if (value != null && mInfo != null && !string.IsNullOrEmpty(mInfo[0].ToString()))
           SetMemberValue(mInfo[0], instance, value);
   }
   else
   {
       mInfo = t.GetMember(fieldName);

       if (mInfo != null && !string.IsNullOrEmpty(mInfo[0].ToString()))
           SetMemberValue(mInfo[0], instance, null);
   }
}

objList.Add(instance);

这解决方案超越了我最初的问题一点点，但它确实表明如何动态地创建一个对象，从而使我们能够在飞行到该对象添加属性。

This solution goes a little bit beyond my initial question, but it does show how to create an object dynamically, hence allowing us to add properties on the fly to that object.
