Quick CodeDOM Question

[Guest]

Hi,

I am working on CodeDOM to generate a more usable class to serialize
and deserialize WXS files. I have hit the wall at a pretty early
stage. :-( I am attempting to change the member public fields into
properties. I have written a generic field to property code for that.
It is almost straight out of the link that you gave me.

But that always creates code with the virtual keyword. I am not sure
on how to get rid of it. For example this is the sample Icon class
created.

public class Icon {
private string _id;
private string _src;
/// <remarks/>
[System.Xml.Serialization.XmlAttributeAttribute()]
public virtual string Id {
get {
return this._id;
}
set {
this._id = value;
}
}
/// <remarks/>
[System.Xml.Serialization.XmlAttributeAttribute()]
public virtual string src {
get {
return this._src;
}
set {
this._src = value;
}
}
}

public virtual string Id ...
public virtual string src ...

As you can see the properties above have the ugly 'virtual' keyword. I
am not sure how to get rid of it.

Can you show us a cut down, compilable, version of the code that generates a virtual property

Sorry about the earlier message. It was rouge HTML. This is a much readable
version of the code. Thanks for all your help.

foreach(CodeTypeDeclaration type in ns.Types)
{
if(type.IsClass || type.IsStruct)
{
CodeTypeMember[] members=new CodeTypeMember[type.Members.Count];
type.Members.CopyTo(members,0);
foreach(CodeTypeMember member in members)
{
if(member is CodeMemberField)
{
CodeMemberProperty prop=new CodeMemberProperty();
prop.Name=member.Name;
prop.Attributes=MemberAttributes.Public;
prop.Type=((CodeMemberField)member).Type;
prop.HasGet=true;
prop.HasSet=true;
prop.CustomAttributes.AddRange(member.CustomAttributes);
member.CustomAttributes.Clear();
prop.Comments.AddRange(member.Comments);
member.Comments.Clear();
member.Attributes=MemberAttributes.Private;
char[] letters=member.Name.ToCharArray();
letters[0]=Char.ToLower(letters[0]);
member.Name=String.Concat("_",new string(letters));
//add get and set
CodeFieldReferenceExpression refReturnStatement=new
CodeFieldReferenceExpression(new CodeThisReferenceExpression(),member.Name);
CodeMethodReturnStatement retStatement=new
CodeMethodReturnStatement(refReturnStatement);
prop.GetStatements.Add(retStatement);
//_member=value
CodeArgumentReferenceExpression refValuePart=new
CodeArgumentReferenceExpression("value");
CodeAssignStatement asStatement=new
CodeAssignStatement(refReturnStatement,refValuePart);
prop.SetStatements.Add(asStatement);
type.Members.Add(prop);
}
}
}

TO save me having to extract the bits from this code snippet that produce the result you see and then create the type form the codeDOM, and so I then don't have to wrap it in a method body and a class just so I can try it out and experiment.

Any chance you could post something short, that *compiles* that shows your issue. I'm sure it will be quicker for you to strip down to the bare essentials your code rather than me try to build it up from what you have provided.
