自定义DateTime XML序列化

问题描述

我想能够将DateTime与不是服务器的特定时区序列化，也不是客户端时间。基本上，任何时区。
是否可以覆盖.Net2.0 webservices中的DateTime序列化？

I would like to be able to Serialize a DateTime with a specific Time Zone that is not the server, nor is it client time. Basically, any time zone.Is it possible to override the DateTime serialization, in .Net2.0 webservices?

我使用xsd.exe编译xmlschema，所以我试图使用XmlSchemaImporter。

I compile an xmlschema using xsd.exe, so I made an attempt using XmlSchemaImporter.

Onserialize示例显示值更改，但不更改输出格式。

The OnSerialize examples show value changes, but not changes to the output format.

XmlSchemaImporter它进入gac，运行xsd.exe和生成的代码，有我想要的类...但该类是一个属性，最终不能被反映。

XmlSchemaImporter, loaded it into the gac, ran xsd.exe, and generated code that has the class I want... but that class is an attribute, which end up not being able to be reflected.

生成的代码

[System.Xml.Serialization.XmlAttributeAttribute()]
public Cuahsi.XmlOverrides.W3CDateTime dateTime {
    get {
        return this.dateTimeField;
    }
    set {
        this.dateTimeField = value;
    }
}

XmlSchemaImporter

XmlSchemaImporter

public class ImportW3CTime :
  System.Xml.Serialization.Advanced.SchemaImporterExtension
{
    public override string ImportSchemaType(string name, string ns,
        XmlSchemaObject context, XmlSchemas schemas,
        XmlSchemaImporter importer, CodeCompileUnit compileUnit,
        CodeNamespace mainNamespace, CodeGenerationOptions options,
        CodeDomProvider codeProvider)
    {
        if (XmlSchema.Namespace == ns)
        {
            switch (name)
            {
                case "dateTime":
                    string codeTypeName = typeof(W3CDateTime).FullName;
                    CodeTypeDeclaration cls =
                        new CodeTypeDeclaration("W3CDateTime");
                    cls.IsStruct = true;
                    cls.Attributes = MemberAttributes.Public;
                    cls.BaseTypes.Add("dateTime");
                    mainNamespace.Types.Add(cls);
                    return codeTypeName;
                default: return null;
            }
        }
        else { return null; }
    }
}

附录1：
我只是累了DateTimeoffset，当类被标记时仍然会导致错误：

Addendum 1:I just tired DateTimeoffset, and that still causes an error when the class is tagged like:

[System.Xml.Serialization.XmlAttributeAttribute(DataType = "dateTime")]
public System.DateTimeOffset metadataDateTime {
    get {
        return this.metadataDateTimeField;
    }
    set {
        this.metadataDateTimeField = value;
    }
}

推荐答案

Don直接序列化 DateTimeOffset ，但序列化一个字符串：

Don't serialize the DateTimeOffset directly, but serialize a string instead:

// Don't serialize this one
[System.Xml.Serialization.XmlIgnore]
public System.DateTimeOffset metadataDateTime
{
    get { ... }
    set { ... }
}


// Serialize this one instead
[System.Xml.Serialization.XmlAttribute("metadataDateTime")]
public string metadataDateTimeXml
{
    get { /* format metadataDateTime to custom format */ }
    set { /* parse metadataDateTime from custom format */ }
}
