如何向XML属性添加命名空间前缀

我有一个表示XML元素的类:

[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")][System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.testingmcafeesites.com/testcat_bl.html")]
[System.Xml.Serialization.XmlRootAttribute("scenario", Namespace = "http://www.testingmcafeesites.com/testcat_bl.html", IsNullable = false)]
public partial class scenario
{
    private string nameField;
    
    private description descriptionField;
    
    /// <remarks />
    [System.Xml.Serialization.XmlAttributeAttribute("name", Namespace = "http://www.testingmcafeesites.com/testcat_bl.html")]
    public string Name
    {
        get { return this.nameField; }
        set { this.nameField = value; }
    }
    
    /// <remarks />
    [System.Xml.Serialization.XmlElementAttribute("description", Namespace = "http://www.testingmcafeesites.com/testcat_bl.html")]
    public description description
    {
        get { return this.descriptionField; }
        set { this.descriptionField = value; }
    }
    
    /// <remarks />
    [System.Xml.Serialization.XmlNamespaceDeclarations]
    public System.Xml.Serialization.XmlSerializerNamespaces XmlNamespaces
    {
        get
        {
            var namespaces = new System.Xml.Serialization.XmlSerializerNamespaces();
            namespaces.Add("epd", "http://www.testingmcafeesites.com/testcat_bl.html");
            return namespaces;
        }
        set { }
    }
}

序列化后,它给出以下结果:

<epd:scenario name="Reuse">

,但我需要得到:

<epd:scenario epd:name="Reuse">

有人能帮我解释一下我应该做什么来实现所需的结果吗?

我试图添加 epd:name 前缀直接进入 XmlAttributeAttribute ,但这里序列化失败了

[System.Xml.Serialization.XmlAttributeAttribute("epd:name", Namespace = "http://www.testingmcafeesites.com/testcat_bl.html")]
public string Name
{
    get { return this.nameField; }
    set { this.nameField = value; }
}
