C＃标志枚举分隔符

Question

我有一个枚举和成员类型

 [Flags]
 public enum SearchFilter
 {
    types = 0x01,
    attributes = 0x02,
    methods = 0x04
 }
 [System.Xml.Serialization.XmlAttribute("search-filter")]
 public SearchFilter search_filter = SearchFilter.types | SearchFilter.attributes | SearchFilter.methods;

序列化此类结果属性时

将是这样的：

<filter search_filter="types attributes methods" />

但需要属性：

<filter search_filter="types|attributes|methods" />

如何在类序列化时更改分隔符？

您必须完全控制它，然后 - 例如我将该成员标记为[XmlIgnore]并添加公共string属性，例如：

[XmlAttribute("search-filter")]
public string SearchShim {
    get { /* translate */ }
    set { /* translate */ }
}
