是什么原因导致此错误在C＃中反序列化XML？

Question

我在C＃中反序列化XML时遇到以下错误，尽管已在我的类中的XMLType和XMLRoot属性上列出了此命名空间。

<ProductRegistrationInterface xmlns='http://www.4cs.com/CLMSchema'> was not expected.

XML看起来像这样：

  <?xml version="1.0"?>
  <ns4CS:ProductRegistrationInterface 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:ns4CS="http://www.4cs.com/CLMSchema">
    <ns4CS:MessageHeader>
      <TargetReference>Some Value</TargetReference>
    </ns4CS:MessageHeader>
    <ProductRegistrations>
      <ProductRegistration>...</ProductRegistration>
      <ProductRegistration>...</ProductRegistration>
      <ProductRegistration>...</ProductRegistration>
    </ProductRegistrations>
  </ns4CS:ProductRegistrationInterface>

ProductRegistrationInterface类如下所示：

[XmlType(AnonymousType = true, Namespace = "http://www.4cs.com/CLMSchema")]
[XmlRoot(Namespace = "http://www.4cs.com/CLMSchema", IsNullable = false)]
public class ProductRegistrationInterface
{
    /// <summary>
    /// Collection of <see cref="ProductRegistration"/> class.
    /// </summary>
    [XmlArray(Namespace = "")]
    [XmlArrayItem(nameof(ProductRegistration), IsNullable = false)]
    public ProductRegistration[] ProductRegistrations { get; set; }        
}

最后这是我正在使用的代码：

XmlSerializer xs = new XmlSerializer(typeof(ProductRegistrationInfo));
StreamReader sr = new StreamReader(@"Test.xml");
ProductRegistrationInfo s = (ProductRegistrationInfo)xs.Deserialize(sr);
sr.Close();

我错过了什么？

类型不匹配：您正在尝试反序列化为ProjectRegistrationInterface类型的实例，但使用为ProductRegistrationInfo类型创建的序列化程序。
