通过ASMX Web服务进行序列化时保持空格/换行符

Question

我正在ASMX Webservice(旧版.NET SOAP服务)中对XML文档进行一些预处理,以便最终在Silverlight前端使用.

我正在将该XML文档处理为POCO对象以便于使用.该对象定义如下:

public class CACDocument : ITextDocument
{
    #region Properties
    public string Title { get; set; }
    public string Text { get; set; }
    public List<Code> CodeList { get; set; }
    public XElement FormatedText { get; set; }
    #endregion

    #region Constructor
    public CACDocument()
    {
        CodeList = new List<Code>();
    }
    #endregion
}

该对象中的Text属性包含基本格式化的文本(换行符,空格等等).提供该属性的XML节点如下所示:

<text>
   A TITLE FOLLOWED BY two line breaks


   Some text followed by a line break

   Some more text that might extend for a paragraph or two followed by more line breaks

   Still more text
</text>

一切都很好,格式保持正如我所期望的那样,Web服务序列化要发送到前端的数据.我猜测在尝试优化带宽时,序列化对象会在发送之前从Text属性中删除额外的空格和换行符.在这个特定的例子中,格式化很重要.有没有办法强制Web服务维护这个空格/换行格式？

我想我编码代替了一些编码来讨论有问题的项目,然后转换回前端,但这让我觉得有点像kludge.

您可以将其序列化为CDATA部分:

    [XmlIgnore]
    public string Text { get; set; }

    private static readonly XmlDocument _xmlDoc = new XmlDocument();

    [XmlElement("Text")]
    public XmlCDataSection TextCData
    {
        get
        {
            return _xmlDoc.CreateCDataSection(Text);
        }
        set
        {
            Text = value.Data;
        }
    }

文本将被序列化为:

<text><![CDATA[A TITLE FOLLOWED BY two line breaks


   Some text followed by a line break

   Some more text that might extend for a paragraph or two followed by more line breaks

   Still more text]]></text>
