C# 在序列化中禁用命名空间属性

我使用以下代码来反序列化一个对象

之后，当我检查返回的节点时，我会得到两个额外的属性 {Attribute，Name=“xmlns:xsi”，Value=”http://www.w3.org/2001/XMLSchema-instance“}对象{System.Xml.xmldattribute} {Attribute，Name=“xmlns:xsd”，Value=”http://www.w3.org/2001/XMLSchema“}对象{System.Xml.xmldattribute}

我想知道如何禁用这两个属性来营救；一个简单（但完整）的示例：

为什么要“禁用”这些属性？他们不应该伤害任何东西。他们应该是一个假设性的陈述。我不希望我的元素中有额外的属性，这就是为什么.BCos我在xml中使用由不同组件读取的相同节点的原因。我希望确保它获得与回滚编辑版本所需的完全相同的输入。如果你需要编辑，请发表评论
