Question

ServiceStack.Text是否可以缩进其xml输出，因此它不是xml的一长行？我们希望将输出写入易于阅读的文本文件中。

您使用的是任何类型的编码吗？因为默认情况下，序列化对象时不会发生任何缩进剥离。请尝试以下代码。

你的xml类对象

 public class MyXMLClass
{
    [XmlElement]
    public string[] Property1 { get; set; }
    [XmlElement]
    public string[] Property2 { get; set; }
}

序列化方法

static void TestXMLWithIndent()
    { 
        var x = new MyXMLClass()
        {
            Property1 = new string[] { "TestProp11", "TestProp12", "TestProp13" },
            Property2 = new string[] { "TestProp21", "TestProp22", "TestProp23" }
        };
        var filename = @"c:\temp\testxmlWithIndent.oxi";
        using (TextWriter textWriter = new StreamWriter(filename))
        {
            XmlSerializer serializer = new XmlSerializer(typeof(MyXMLClass));
            serializer.Serialize(textWriter, x);
            textWriter.Close();
        }
    }

此代码生成正确的缩进。而下面的代码生成的xml文件没有你提到的缩进。请注意，我使用xmltextwriter时必须使用编码。

 static void XmlWithNoIndent()
    {
        var x = new MyXMLClass()
        {
            Property1 = new string[] { "TestProp11", "TestProp12", "TestProp13" },
            Property2 = new string[] { "TestProp21", "TestProp22", "TestProp23" }
        };
        var filename = @"c:\temp\testxmlWithNoIndent.oxi"; 
        using (MemoryStream memoryStream = new MemoryStream())
        {
            using (var xmlTextWriter = new System.Xml.XmlTextWriter(memoryStream, Encoding.Unicode))
            {
                XmlSerializer xs = new XmlSerializer(typeof(MyXMLClass));
                xs.Serialize(xmlTextWriter, x);

                MemoryStream memoryBaseStream;
                memoryBaseStream = (MemoryStream)xmlTextWriter.BaseStream;
                UTF8Encoding encoding = new UTF8Encoding();
                File.WriteAllBytes(filename, memoryStream.ToArray());
                memoryBaseStream.Dispose();
                xmlTextWriter.Close();
                memoryStream.Close();
            }
        }
    }

ServiceStack.Text xml序列化格式良好的输出
