.net - 从 XmlSchema .net 的输出中删除 docType 声明

Question

以下代码:

        XmlSchema xmlSchema = new XmlSchema();

        XmlSchemaElement xmlSchemaElement = new XmlSchemaElement();            
        xmlSchemaElement.Name = "SomeElement";
        xmlSchema.Items.Add(xmlSchemaElement);

        XmlNamespaceManager xmlNamespaceManager = new XmlNamespaceManager(new NameTable());
        xmlNamespaceManager.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");

        StringWriter stringWriter = new StringWriter();            
        xmlSchema.Write(stringWriter, xmlNamespaceManager);

        String result = stringWriter.ToString();

给我:

<?xml version="1.0" encoding="utf-16"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="SomeElement" />
</xs:schema>

我不需要 docType 声明。

显然我可以删除第一行。但是，有谁知道有什么方法可以阻止 XmlSchema 类首先编写 docType 声明吗？

不是直接写入您的 StringWriter，而是写入 XmlWriter。这样，您就可以设置特定的序列化选项。

StringWriter stringWriter = new StringWriter();

XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true; // <-- this is what you care about
XmlWriter xmlWriter = XmlWriter.Create(stringWriter, settings);
xmlSchema.Write(xmlWriter, xmlNamespaceManager);

String result = stringWriter.ToString();
