假设我有一个像这样的xsd文件
<!-- <?xml version="1.0" encoding="utf-8"?>
<xs:schema... scheme and etc here-->
<xs:element name="data_container" >
<xs:complexType>
<xs:sequence>
<xs:element name="people">
<xs:complexType>
<xs:sequence>
<xs:element name="person" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="some_data">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute name="sx" use="required" >
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="M"/>
<xs:enumeration value="F"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="p_id" type="xs:ID" use="required" />
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="other_properties">
<xs:complexType>
<xs:sequence>
<xs:element name="introduction_txt" type="xs:string"/>
<xs:element name="introduction_pic" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
我也是由视觉工作室课程生成的，我想你明白我的意思所以我不会发布代码（只有你会询问它:)）。
所以我尝试创建xml这样的文件（我以为我在这里找到了解决方案所以我用它作为例子How can I build XML in C#?，第二个答案）
但我这样得到错误。
我在这里得到NullReferenceException
newDC.other_properties.introduction_txt =＆＃34; Lorem ipsum dolor sit 阿梅特＆＃34 ;;
如何使用generated-from-xsd类帮助正确写入xml文件？
using System;
using System.Collections.Generic;
using System.Linq;
using System.Xml.Linq;
using System.Text;
namespace xsdTests
{
class Program
{
static void Main(string[] args)
{
xmlGenTest();
}
static void xmlGenTest()
{
XDocument doc = new XDocument();
data_container newDC = new data_container();
newDC.other_properties.introduction_txt = "Lorem ipsum dolor sit amet";
doc.Add(newDC);
doc.Save("C:\\temp\\data.xml");
}
}
}

答案 0 :(得分：1)
如果您已经将XSD转换为可用类（使用XSD.exe / XSDGenerator.exe）并且已在项目中包含该新类文件，那么您只需引用该类/创建它的新实例在使用它之前。 （在序列化之前，如果需要的话）。
修改
按如下方式更改xmlGenTest方法：
static void XmlGenTest()
{
var doc = new XDocument();
var x = new data_container();
x.other_properties = new data_containerOther_properties { introduction_pic = "a", introduction_txt = "b" };
x.people = new data_containerPerson[1];
x.people[0] = new data_containerPerson
{
p_id = "",
some_data = new data_containerPersonSome_data { sx = data_containerPersonSome_dataSX.F }
};
doc.Add(x);
doc.Save("C:\\temp\\data.xml");
}
如果您需要序列化构建的对象（示例），那么您可以在此之后执行此操作，如果您需要课程或帮助，请告诉我。
我希望这有帮助吗？
