如何在XmlTextWriter中设置Settings属性,以便我可以在自己的行上编写每个XML属性？

Question

我有一些代码,它将一个对象序列化为一个文件.我正在尝试将每个XML属性输出到单独的行.代码如下所示:

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);
    }
}

唯一的问题是,对象的Settings属性XmlTextWriter是只读的.

如何Settings在XmlTextWriter对象上设置属性,以便NewLineOnAttributes设置有效？

嗯,我以为我需要一个XmlTextWriter,因为XmlWriter是一个abstract班级.如果你问我,有点困惑. 最终的工作代码在这里:

/// <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);
    }
}

Answer 1

使用静态Create()方法XmlWriter.

XmlWriter.Create(filePath, settings);

请注意,您可以NewLineOnAttributes在设置中设置属性.

Answer 2

我知道这个问题很老了，无论如何实际上可以为XMLTextWriter. 与 不同的是XMLwriter，您不必通过设置；你应该使用该Formatting属性：

XmlTextWriter writer = new XmlTextWriter(filePath, Encoding.UTF8);
w.Formatting = Formatting.Indented;
