C# 如何控制XmlSerializer添加默认命名空间的位置

我试图控制将默认名称空间添加到

XmlSerializer

的输出中的级别

到目前为止我已经

<GetAccountDetailRequestStructure>
  <AccountRef xmlns="http://www.govtalk.gov.uk/NAC/GetAccountDetail">4026069</AccountRef>
  <AccountType xmlns="http://www.govtalk.gov.uk/NAC/GetAccountDetail">C</AccountType>
  <SelectionOptions xmlns="http://www.govtalk.gov.uk/NAC/GetAccountDetail">
    <FromDate>2000-01-01</FromDate>
    <ToDate>2015-10-23</ToDate>
    <IncludeAccountSummary>false</IncludeAccountSummary>
  </SelectionOptions>
</GetAccountDetailRequestStructure>

但我想得到的是

<GetAccountDetailRequestStructure xmlns="http://www.govtalk.gov.uk/NAC/GetAccountDetail">
  <AccountRef>4026069</AccountRef>
  <AccountType>C</AccountType>
  <SelectionOptions>
    <FromDate>2000-01-01</FromDate>
    <ToDate>2015-10-23</ToDate>
    <IncludeAccountSummary>false</IncludeAccountSummary>
  </SelectionOptions>
</GetAccountDetailRequestStructure>

4026069
C
2000-01-01
2015-10-23
假的

我认为这相当于第一个XML示例

尝试将默认名称空间传递给

XmlSerializer

的

const string defaultNamespace = "http://www.govtalk.gov.uk/NAC/GetAccountDetail";
var ns = new XmlSerializerNamespaces();
ns.Add(string.Empty, defaultNamespace);

// Note the 2nd constructor argument.
var xs = new XmlSerializer(typeof(T), defaultNamespace);

xs.Serialize(xmlWriter, obj, ns);

它们不是等价物。在第一个示例中，

GetAccountDetailRequestStructure

位于全局命名空间中。@Damien\u the\u Noisever OK，如果是全局命名空间，如何在XmlSerializer中控制它

const string defaultNamespace = "http://www.govtalk.gov.uk/NAC/GetAccountDetail";
var ns = new XmlSerializerNamespaces();
ns.Add(string.Empty, defaultNamespace);

// Note the 2nd constructor argument.
var xs = new XmlSerializer(typeof(T), defaultNamespace);

xs.Serialize(xmlWriter, obj, ns);
