C#-反序列化具有多个ns的XML文件

大约进行到一半时，出现以下问题：

<ax26:frentista_id>0</ax26:frentista_id
ax26:horimetro_anterior>0</ax26:horimetro_anterior>

两行都缺少尖括号（<和>）。。。

您需要像一样声明名称空间ns和ax26

<ns:obterControleDieselResponse xmlns:ns="http://x.y.z">
    <ns:return type="br.com.framew2.webservices.posicoes.RetornoDiesel" xmlns:ax26="http://a.b.c.d">
        <ax26:diesel type="br.com.framew2.webservices.posicoes.ControleDiesel">

编辑：

要在代码中声明命名空间，可以尝试使用类似的XmlNamespaceManager

var xmlDoc = new XmlDocument();
xmlDoc.Load(PathToFile);
var nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("ns", "http://x.y.z");
nsmgr.AddNamespace("ax26", "http://a.b.c.d");
var node = doc.SelectSingleNode("//ns:obterControleDieselResponse", nsmgr);
