我有这段代码，它将一个对象序列化为一个文件。我试图让每个 XML 属性在单独的行上输出。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在对象上设置属性XmlTextWriter，以便NewLineOnAttributes设置生效？

好吧，我想我需要一个XmlTextWriter, 因为XmlWriter是一个abstract类。如果你问我，有点令人困惑。 最终工作代码在这里：

/// <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);
    }
}

使用 的静态Create()方法XmlWriter。

XmlWriter.Create(filePath, settings);

请注意，您可以NewLineOnAttributes在设置中设置属性。

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

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