我是否有办法在.NET中序列化对象,而XML Namespaces也不会自动序列化?似乎默认情况下.NET认为应该包含XSI和XSD名称空间,但我不希望它们存在。

obj
并且已经定义。将具有单个空命名空间的XMLSerializerNamespace添加到集合中可以解决问题。
在这样的VB中:
Dim xs As New XmlSerializer(GetType(cEmploymentDetail))
Dim ns As New XmlSerializerNamespaces()
ns.Add("", "")
Dim settings As New XmlWriterSettings()
settings.OmitXmlDeclaration = True
Using ms As New MemoryStream(), _
sw As XmlWriter = XmlWriter.Create(ms, settings), _
sr As New StreamReader(ms)
xs.Serialize(sw, obj, ns)
ms.Position = 0
Console.WriteLine(sr.ReadToEnd())
End Using
在C#中就像这样:
//Create our own namespaces for the output
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
//Add an empty namespace and empty value
ns.Add("", "");
//Create the serializer
XmlSerializer slz = new XmlSerializer(someType);
//Serialize the object with our own namespaces (notice the overload)
slz.Serialize(myXmlTextWriter, someObject, ns);

如果您想要删除额外的xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
和xmlns:xsd="http://www.w3.org/2001/XMLSchema"
,但仍保留自己的名称空间xmlns="http://schemas.YourCompany.com/YourSchema/"
,则除了这个简单的更改之外,您使用与上面相同的代码:< / p>
// Add lib namespace with empty prefix
ns.Add("", "http://schemas.YourCompany.com/YourSchema/");

如果你想删除名称空间,你可能还想删除版本,以节省你的搜索我已经添加了这个功能,所以下面的代码将同时执行这两个。
我还将它包装在一个通用方法中,因为我创建了非常大的xml文件,这些文件太大而无法在内存中进行序列化,因此我将输出文件中断并将其序列化为较小的&#34;大块&#34;:
public static string XmlSerialize<T>(T entity) where T : class
{
// removes version
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
XmlSerializer xsSubmit = new XmlSerializer(typeof(T));
using (StringWriter sw = new StringWriter())
using (XmlWriter writer = XmlWriter.Create(sw, settings))
{
// removes namespace
var xmlns = new XmlSerializerNamespaces();
xmlns.Add(string.Empty, string.Empty);
xsSubmit.Serialize(writer, entity, xmlns);
return sw.ToString(); // Your XML
}
}

我建议这个助手类:
public static class Xml
{
#region Fields
private static readonly XmlWriterSettings WriterSettings = new XmlWriterSettings {OmitXmlDeclaration = true, Indent = true};
private static readonly XmlSerializerNamespaces Namespaces = new XmlSerializerNamespaces(new[] {new XmlQualifiedName("", "")});
#endregion
#region Methods
public static string Serialize(object obj)
{
if (obj == null)
{
return null;
}
return DoSerialize(obj);
}
private static string DoSerialize(object obj)
{
using (var ms = new MemoryStream())
using (var writer = XmlWriter.Create(ms, WriterSettings))
{
var serializer = new XmlSerializer(obj.GetType());
serializer.Serialize(writer, obj, Namespaces);
return Encoding.UTF8.GetString(ms.ToArray());
}
}
public static T Deserialize<T>(string data)
where T : class
{
if (string.IsNullOrEmpty(data))
{
return null;
}
return DoDeserialize<T>(data);
}
private static T DoDeserialize<T>(string data) where T : class
{
using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(data)))
{
var serializer = new XmlSerializer(typeof (T));
return (T) serializer.Deserialize(ms);
}
}
#endregion
}

如果你无法摆脱每个元素的额外xmlns属性,那么当从生成的类序列化为xml时(例如:当使用 xsd.exe 时),所以你有类似的东西: / p>
<manyElementWith xmlns="urn:names:specification:schema:xsd:one" />
然后我会与你分享对我有用的东西(以前的答案和我发现的here的混合物)
显式设置所有不同的xmlns,如下所示:
Dim xmlns = New XmlSerializerNamespaces()
xmlns.Add("one", "urn:names:specification:schema:xsd:one")
xmlns.Add("two", "urn:names:specification:schema:xsd:two")
xmlns.Add("three", "urn:names:specification:schema:xsd:three")
然后将其传递给序列化
serializer.Serialize(writer, object, xmlns);
您将在根元素中声明三个名称空间,并且不再需要在其他元素中生成相应的前缀
<root xmlns:one="urn:names:specification:schema:xsd:one" ... />
<one:Element />
<two:ElementFromAnotherNameSpace /> ...
