适用于

XmlTypeAttribute(String)

初始化 XmlTypeAttribute 类的新实例,并指定 XML 类型的名称。

public:
 XmlTypeAttribute(System::String ^ typeName);
public XmlTypeAttribute (string typeName);
public XmlTypeAttribute (string? typeName);
new System.Xml.Serialization.XmlTypeAttribute : string -> System.Xml.Serialization.XmlTypeAttribute
Public Sub New (typeName As String)

参数

typeName
String

XmlSerializer 序列化类实例时生成(和在反序列化类实例时识别)的 XML 类型的名称。

注解

XmlTypeAttribute将类应用于指定 XML 类型的命名空间、XML 类型名称以及是否在 XML 架构文档中包括该类型。 若要查看设置类属性的结果 XmlTypeAttribute ,请将应用程序编译为可执行文件或 DLL,并将生成的文件传递给 XML 架构定义工具 (Xsd.exe) 。 该工具将编写架构,包括类型定义。
