.NET reflection question

I'm trying to do something similar to the WinCV utility that ships with .NET.  I want to select any class and generate code that describes that class just as WinCV does in the right-hand pane.  When creating fields, I have this code...

//Fields
FieldInfo [] fields = dt.GetFields();
foreach(FieldInfo fld in fields)
{
CodeMemberField cmf = new CodeMemberField(fld.FieldType, fld.Name);
cmf.Attributes = (MemberAttributes)fld.FieldType.MemberType;
                        
if(fld.IsFamily) cmf.Attributes |= MemberAttributes.Family;
if(fld.IsFamilyAndAssembly) cmf.Attributes |= MemberAttributes.FamilyAndAssembly;
if(fld.IsFamilyOrAssembly) cmf.Attributes |= MemberAttributes.FamilyOrAssembly;
if(fld.IsPrivate) cmf.Attributes |= MemberAttributes.Private;
if(fld.IsPublic) cmf.Attributes |= MemberAttributes.Public;
if(fld.IsStatic) cmf.Attributes |= MemberAttributes.Static;

//Const?
if(fld.IsLiteral)
{
      if(!fld.IsInitOnly)
            cmf.Attributes |= MemberAttributes.Const;
      else
      {
            //readonly
      }
}


My problem is a) this is ugly.  I thought there would be an override somewhere in "CodeMemberField" that took a FieldInfo type as a parameter and set the properties for me.  I could not find such a member so I have to resort to this ugly way.  The other problem is that there is no MemberAttributes enum that describes the readonly property.  So when running my code on the System.DateTime class I'm getting

    public static System.DateTime MinValue;
    public static System.DateTime MaxValue;

when I should (according to WinCV) be getting

    public static readonly System.DateTime MinValue;
    public static readonly System.DateTime MaxValue;


Thanks in advance.
