如何设置在XmlTextWriter的设置属性，让我可以写上自己的行每个XML属性？ [英] How do I set the Settings property in XmlTextWriter, so that I can write each XML attribute on its own line?

问题描述

我有这样的一些代码，其中序列化对象到一个文件。我试图让每个XML属性输出在单独一行。代码如下：

 公共静态无效ToXMLFile（obj对象，字符串文件路径）
 {
 XmlSerializer的序列化=新的XmlSerializer（obj.GetType（））; 
 
 XmlWriterSettings设置=新XmlWriterSettings（）; 
 settings.NewLineOnAttributes = TRUE; 
 
 XmlTextWriter的作家=新的XmlTextWriter（文件路径，Encoding.UTF8）; 
 writer.Settings =设置; //这里失败。属性为只读。使用（流baseStream = writer.BaseStream）
 {
 serializer.Serialize 
 
（作家，OBJ）; 
} 
} 
  

唯一的问题是，在在的XmlTextWriter 对象设置属性是只读的。

如何设置设置在的XmlTextWriter 对象，使 NewLineOnAttributes 设置是否行得通呢？

好吧，我想我需要一个的XmlTextWriter ，因为的XmlWriter 是摘要类。如果你问我有点困惑。的最后的工作代码是在这里：的

  ///<总结> 
 ///序列化对象到XML文件;写每个XML属性到一个新行。 
 ///< /总结> 
公共静态无效ToXMLFile（obj对象，字符串文件路径）
 {
 XmlSerializer的序列化=新的XmlSerializer（obj.GetType（））; 
 
 XmlWriterSettings设置=新XmlWriterSettings（）; 
 settings.Indent = TRUE; 
 settings.NewLineOnAttributes = TRUE;使用（XmlWriter的作家= XmlWriter.Create（文件路径，设置））
 {
 serializer.Serialize 
 
（作家，OBJ）; 
} 
} 
  

解决方案

使用静态创建（） 的XmlWriter 。

的方法

  XmlWriter.Create（文件路径，设置）; 
  

请注意，您可以设置 NewLineOnAttributes 属性在设置

I have this bit of code, which serializes an object to a file. I'm trying to get each XML attribute to output on a separate line. The code looks like this:

public static void ToXMLFile(Object obj, string filePath)
{
    XmlSerializer serializer = new XmlSerializer(obj.GetType());

    XmlWriterSettings settings = new XmlWriterSettings();
    settings.NewLineOnAttributes = true;

    XmlTextWriter writer = new XmlTextWriter(filePath, Encoding.UTF8);
    writer.Settings = settings; // Fails here.  Property is read only.

    using (Stream baseStream = writer.BaseStream)
    {
        serializer.Serialize(writer, obj);
    }
}

The only problem is, the Settings property of the XmlTextWriter object is read-only.

How do I set the Settings property on the XmlTextWriter object, so that the NewLineOnAttributes setting will work?

Well, I thought I needed an XmlTextWriter, since XmlWriter is an abstract class. Kinda confusing if you ask me. Final working code is here:

/// <summary>
/// Serializes an object to an XML file; writes each XML attribute to a new line.
/// </summary>
public static void ToXMLFile(Object obj, string filePath)
{
    XmlSerializer serializer = new XmlSerializer(obj.GetType());

    XmlWriterSettings settings = new XmlWriterSettings();
    settings.Indent = true;
    settings.NewLineOnAttributes = true;

    using (XmlWriter writer = XmlWriter.Create(filePath, settings))
    {
        serializer.Serialize(writer, obj);
    }
}

解决方案

Use the static Create() method of XmlWriter.

XmlWriter.Create(filePath, settings);

Note that you can set the NewLineOnAttributes property in the settings.
