使用多个VARYING命名空间反序列化XML？

Question

我正在尝试反序列化XML报告。这是从XML生成的类（类很好）。但是，命名空间确实在SQL服务器版本之间有所不同。

例如报告命名空间是

"http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition"

在下面的例子中也可以

"http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition"

等等

另外我假设这个命名空间可以变化

"http://schemas.microsoft.com/SQLServer/reporting/reportdesigner"

如何使用不同的命名空间反序列化XML（不为每个可能的命名空间创建单独的类）？

这是我的XML类：

using System.Xml.Serialization;
using System.Collections.Generic;

如何读取命名空间，然后在文本中替换它，然后从替换的文本反序列化？ 由于您有一个报告，因此名称空间文本出现在内容中某处的可能性应该是远程的......

public RdlReader OpenXml(string xml)
{
    System.Xml.XmlDocument document = new System.Xml.XmlDocument();
    document.XmlResolver = null;
    document.PreserveWhitespace = true;
    document.LoadXml(xml);

    string default_namespace = Xml2CSharp.Report.DEFAULT_NAMESPACE;
    string designer_namespace = Xml2CSharp.Report.DESIGNER_NAMESPACE;

    if (document.DocumentElement.HasAttribute("xmlns"))
        default_namespace = document.DocumentElement.Attributes["xmlns"].Value;

    if (document.DocumentElement.HasAttribute("xmlns:rd"))
        designer_namespace = document.DocumentElement.Attributes["xmlns:rd"].Value;

    this.m_xml = xml
        .Replace(default_namespace, Xml2CSharp.Report.DEFAULT_NAMESPACE)
        .Replace(designer_namespace, Xml2CSharp.Report.DESIGNER_NAMESPACE);

    document = null;


    document = new System.Xml.XmlDocument();
    document.XmlResolver = null;
    document.PreserveWhitespace = true;
    document.LoadXml(this.m_xml);


    Xml2CSharp.Report rep = Tools.XML.Serialization.DeserializeXmlFromString<Xml2CSharp.Report>(this.m_xml);
    System.Console.WriteLine(rep);

    this.m_document = document;
    this.m_nsmgr = GetReportNamespaceManager(this.m_document);

    return this;
}

像这样：

[XmlRoot(ElementName = "Report",
    Namespace = Report.DEFAULT_NAMESPACE)]
public class Report
{
    public const string DEFAULT_NAMESPACE = "http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition";
    public const string DESIGNER_NAMESPACE = "http://schemas.microsoft.com/SQLServer/reporting/reportdesigner";
    [...]
