使用XSD.exe生成的这些类级别属性中的哪一个可以安全地丢弃？

Question

I used XSD.exe against an XML schema file ( .XSD ) to generate C# classes for use in deserializing XML data files that conform to the said XML schema.

I noticed the following class level attributes have been added to all the generated classes.

[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.17929")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]

In some cases, the tool has also generated the XmlElementAttribute attribute, which I am well aware is necessary for proper deserialization.

[System.Xml.Serialization.XmlElementAttribute("Field")]

So other than this XmlElementAttribute , which of the aforementioned attributes are really required for deserialization to be successful. I know I can remove them 1 by 1 and try it out, but there are a lot of classes and I want to keep my class definitions as 'clean' as possible without having un-necessary attributes all over the place.

Here's a sample class definition generated by XSD.exe , in case you need to look at the class also.

[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.17929")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]
public partial class CrystalReportReportFooter {

    private CrystalReportReportFooterSection sectionField;

    /// <remarks/>
    public CrystalReportReportFooterSection Section {
        get {
            return this.sectionField;
        }
        set {
            this.sectionField = value;
        }
    }
}

Thank you,

Should be safe to remove unless the tool that regenerates the code needs this.

[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.17929")]

You need this as this is what tells a class that it can be serialized.

[System.SerializableAttribute()]

This can be removed. It's purely for debugging and may end up hindering debugging later on if you add custom code.

[System.Diagnostics.DebuggerStepThroughAttribute()]

---

This can be removed. Only used for the IDE or any WYSIWYG designer that takes advantage of it.

[System.ComponentModel.DesignerCategoryAttribute("code")]

---

This is up to you. Basically it is telling the Serializer that the class is an anonymous XSD type.

[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]
