如何在XmlTextWriter中設置Settings屬性，以便我可以在自己的行上編寫每個XML屬性？

Question

我有這段代碼，它將一個對象序列化爲一個文件。我試圖讓每個XML屬性在一個單獨的行上輸出。代碼如下所示：

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); 
    } 
} 

唯一的問題是，在XmlTextWriter對象的Settings屬性爲只讀。

如何在XmlTextWriter對象上設置Settings屬性，以便NewLineOnAttributes設置可以使用？

嗯，我想我需要一個XmlTextWriter，因爲XmlWriter是abstract類。如果你問我，有點令人困惑。 最後的工作代碼是在這裏：

/// <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

使用的XmlWriter靜態Create()方法。

XmlWriter.Create(filePath, settings); 

請注意，您可以在設置中設置NewLineOnAttributes屬性。

Answer 2

我知道這個問題很舊，無論如何它實際上可以設置XMLTextWriter的縮進。與XMLwriter不同，您不必通過設置;你應該使用Formatting屬性：

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