我希望能够使用不是服务器的特定时区序列化DateTime,也不是客户端时间.基本上,任何时区.
是否可以在.Net2.0 webservices中覆盖DateTime序列化?
我使用xsd.exe编译xmlschema,所以我尝试使用XmlSchemaImporter.
OnSerialize示例显示值更改,但不更改输出格式.
XmlSchemaImporter,将其加载到gac中,运行xsd.exe,并生成具有我想要的类的代码……但该类是一个属性,最终无法反映.
[InvalidOperationException: Cannot
serialize member ‘metadataDateTime’ of
type Cuahsi.XmlOverrides.W3CDateTime.
XmlAttribute/XmlText cannot be used to
encode complex types.]
生成的代码
[System.Xml.Serialization.XmlAttributeAttribute()]
public Cuahsi.XmlOverrides.W3CDateTime dateTime {
get {
return this.dateTimeField;
}
set {
this.dateTimeField = value;
}
}
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; }
}
}

我只是厌倦了DateTimeoffset,当类被标记为时仍然会导致错误:
[System.Xml.Serialization.XmlAttributeAttribute(DataType = "dateTime")]
public System.DateTimeOffset metadataDateTime {
get {
return this.metadataDateTimeField;
}
set {
this.metadataDateTimeField = value;
}
}
最佳答案 不要直接序列化DateTimeOffset,而是序列化字符串:
// 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 */ }
}
