C＃将对象序列化为xml而不进行格式化

Question

我需要将c＃对象序列化为xml，我可以像格式化部分中那样进行操作，但是我们可以在没有缩进/多余空格/换行的格式化情况下实现它。这是必需的，因为我们需要将整个对象写到一个csv中，因此我们需要一个缩小的版本。我尝试了几个XmlWriterSettings，但是没有按预期工作。任何代码片段都将提供很大的帮助，要序列化的对象可以具有其他引用类型，这些成员可以从其他基类继承，因此序列化器可能需要已知的类型

格式化的XML：

<ArrayOfStock xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Stock>
    <ProductCode>12345</ProductCode>
    <ProductPrice>10.32</ProductPrice>
  </Stock>
  <Stock>
    <ProductCode>45632</ProductCode>
    <ProductPrice>5.43</ProductPrice>
  </Stock>
</ArrayOfStock>

无格式：

<ArrayOfStock xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><Stock><ProductCode>123456</ProductCode><ProductPrice>10.57</ProductPrice></Stock><Stock><ProductCode>789123</ProductCode><ProductPrice>133.22</ProductPrice></Stock></ArrayOfStock>

尝试过的代码：

Type[] _knownExpressions = new Type[]
{
     typeof(SimpleExpression),
     typeof(CompositeExpression)
};
string expression = string.Empty;
MemoryStream ms = new MemoryStream();
DataContractSerializer dcs = new DataContractSerializer(typeof(Expression), _knownExpressions);                                        
using (XmlTextWriter xmlTextWriter = new XmlTextWriter(ms, System.Text.Encoding.Default))
{
      xmlTextWriter.Formatting = Formatting.None;
      dcs.WriteObject(xmlTextWriter, expression);
      xmlTextWriter.Flush();
      xmlTextWriter.BaseStream.Position = 0;
      StreamReader sr = new StreamReader(xmlTextWriter.BaseStream);
      expression = sr.ReadToEnd();
      sr.Close();
 }

不介意，我没有将正确的对象传递给序列化器，以下工作

Type[] _knownExpressions = new Type[]
{
     typeof(SimpleExpression),
     typeof(CompositeExpression)
};
string expression = string.Empty;
Expression exp = new Expression(){
   // Fill the object
};
MemoryStream ms = new MemoryStream();
DataContractSerializer dcs = new DataContractSerializer(typeof(Expression), _knownExpressions);                                        
using (XmlTextWriter xmlTextWriter = new XmlTextWriter(ms, System.Text.Encoding.Default))
{
      xmlTextWriter.Formatting = Formatting.None;
      dcs.WriteObject(xmlTextWriter, exp);
      xmlTextWriter.Flush();
      xmlTextWriter.BaseStream.Position = 0;
      StreamReader sr = new StreamReader(xmlTextWriter.BaseStream);
      expression = sr.ReadToEnd();
      sr.Close();
 }
