[英]Generate XML from C# Class with specific attributes
我遇到了有关C#中类的XML序列化的问题:我想要的是以下格式的XML
<?xml version="1.0" encoding="utf-8"?>
<MyClass:Req xsi:schemaLocation="http://www.Test.com/MyClass.xsd"
xmlns:TestClass="http://www.Test.com/MyClass"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.Test.com/MyClass">
<head>
<hA>01</hA>
</head>
<body>
<R1>0</R1>
<R3 />
<R4 />
</body>
</MyClass:Req>
所有XMLNS属性都是必需的,并且需要通过代码进行配置。 我当前得到的输出是:
<?xml version="1.0" encoding="utf-8"?>
<MyClass_x003A_Req xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.Test.com/MyClass">
<head>
<hA>01</hA>
</head>
<body>
<R1>0</R1>
<R3 />
<R4 />
</body>
</MyClass_x003A_Req>
如您所见,包含序言的行不正确,我需要它仅显示第一个XML示例中的值。 另外,冒号也被转换为x003A ,我需要将其设为冒号。
这是我目前正在使用的代码,请记住它只是测试代码,这些字段将在生产前进行更改。
request theReq = new request();
requestHead rHead = new requestHead();
requestBody rBody = new requestBody();
rHead.hA = "01";
rBody.R1 = "0";
theReq.head = rHead;
theReq.body = rBody;
XmlSerializer serializer = new XmlSerializer(typeof(request));
TextWriter textWriter = new StreamWriter(@"Test.xml");
serializer.Serialize(textWriter, theReq);
textWriter.Close();
[XmlRoot(Namespace = "http://www.Test.com/MyClass",
ElementName = "MyClass:Req",
DataType = "string",
IsNullable = true)]
public partial class request
{
private requestHead headField;
private requestBody bodyField;
public request()
{
this.bodyField = new requestBody();
this.headField = new requestHead();
}
public requestHead head
{
get
{
return this.headField;
}
set
{
this.headField = value;
}
}
public requestBody body
{
get
{
return this.bodyField;
}
set
{
this.bodyField = value;
}
}
}
public partial class requestHead
{
private string headAField;
private string headBField;
public string hA
{
get
{
return this.headAField;
}
set
{
this.headAField = value;
}
}
public string hB
{
get
{
return this.headBField;
}
set
{
this.headBField = value;
}
}
}
public partial class requestBody
{
private string R1Field;
private string R2Field;
private requestBodyR3 R3Field;
private requestBodyR4 R4Field;
public requestBody()
{
this.R4Field = new requestBodyR4();
this.R3Field = new requestBodyR3();
}
public string R1
{
get
{
return this.R1Field;
}
set
{
this.R1Field = value;
}
}
public string R2
{
get
{
return this.R2Field;
}
set
{
this.R2Field = value;
}
}
public requestBodyR3 R3
{
get
{
return this.R3Field;
}
set
{
this.R3Field = value;
}
}
public requestBodyR4 R4
{
get
{
return this.R4Field;
}
set
{
this.R4Field = value;
}
}
}
public partial class requestBodyR3
{
private string R31Field;
private string R32Field;
public string R31
{
get
{
return this.R31Field;
}
set
{
this.R31Field = value;
}
}
public string R32
{
get
{
return this.R32Field;
}
set
{
this.R32Field = value;
}
}
}
public partial class requestBodyR4
{
private string R41Field;
public string R41
{
get
{
return this.R41Field;
}
set
{
this.R41Field = value;
}
}
}
我知道我需要更改XMLRoot行以实现所需的输出,但是我不确定在这里需要更改什么?
另外,我如何在将COLON写入文件之前强制保留COLON,而不将其修改为x003A 。
最后一个问题,因为我没有填充R3和R4,如果没有填充值,就像没有将R2和R4写入文件一样,我可以防止它们被写入XML,我相信区别是R2是字符串以及R3和R4是复杂类型,使得序列化程序更难确定是否应写入它们?
编辑:
应用Ralp的建议更改后,单击确定,该文件现在如下所示:
<?xml version="1.0" encoding="utf-8"?>
<MyClass:Req d1p1:schemaLocation="http://www.test.com/myclass.xsd"
xmlns:d1p1="http://www.w3.org/2001/XMLSchema-instance"
xmlns:MyClass="http://www.test.com/myclass">
<head>
<hA>01</hA>
</head>
<body>
<R1>0</R1>
<R3 />
<R4 />
</body>
</MyClass:Req>
如何更改xsi的d1p1?
另外缺少的一行是xmlns =“ http://www.Test.com/MyClass”>,我该如何添加呢?
编辑-2:
几乎有了Ralp的帮助,这是更新的文件:
<?xml version="1.0" encoding="utf-8"?>
<MyClass:Req xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.test.com/myclass.xsd"
xmlns:MyClass="http://www.test.com/myclass">
<head>
<hA>01</hA>
</head>
<body>
<R1>0</R1>
<R3 />
<R4 />
</body>
</MyClass:Req>
并更新了CODE:
request theReq = new request();
requestHead rHead = new requestHead();
requestBody rBody = new requestBody();
rHead.hA = "01";
rBody.R1 = "0";
theReq.head = rHead;
theReq.body = rBody;
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("xsi", "http://www.w3.org/2001/XMLSchema-instance");
ns.Add("MyClass", "http://www.test.com/myclass");
XmlSerializer serializer = new XmlSerializer(typeof(request));
TextWriter textWriter = new StreamWriter(@"Test.xml");
serializer.Serialize(textWriter, theReq, ns);
textWriter.Close();
[XmlRoot(Namespace = "http://www.test.com/myclass", ElementName = "Req")]
public partial class request
{
private requestHead headField;
private requestBody bodyField;
public request()
{
this.bodyField = new requestBody();
this.headField = new requestHead();
}
[XmlAttribute("schemaLocation", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
public string xsiSchemaLocation = "http://www.test.com/myclass.xsd";
[XmlElement("head", Namespace = "")]
public requestHead head
{
get
{
return this.headField;
}
set
{
this.headField = value;
}
}
[XmlElement("body", Namespace = "")]
public requestBody body
{

{
return this.bodyField;
}
set
{
this.bodyField = value;
}
}
}
public partial class requestHead
{

private string headBField;
public string hA
{

{
return this.headAField;
}
set
{
this.headAField = value;
}
}
public string hB
{
get
{
return this.headBField;
}
set
{
this.headBField = value;
}
}
}
public partial class requestBody
{
private string R1Field;
private string R2Field;
private requestBodyR3 R3Field;
private requestBodyR4 R4Field;
public requestBody()
{
this.R4Field = new requestBodyR4();
this.R3Field = new requestBodyR3();
}
public string R1
{
get
{
return this.R1Field;
}
set
{
this.R1Field = value;
}
}
public bool ShouldSerializeR1() { return !String.IsNullOrEmpty(R1); }
public string R2
{
get
{
return this.R2Field;
}
set
{
this.R2Field = value;
}
}
public bool ShouldSerializeR2() { return !String.IsNullOrEmpty(R2); }
public requestBodyR3 R3
{
get
{
return this.R3Field;
}
set
{
this.R3Field = value;
}
}
public bool ShouldSerializeR3() { return requestBodyR3.ShouldSerializeRequestBodyR3(); }
public requestBodyR4 R4
{
get
{
return this.R4Field;
}
set
{
this.R4Field = value;
}
}
}
public partial class requestBodyR3
{
private string R31Field;
private string R32Field;
public static bool ShouldSerializeRequestBodyR3()
{
bool blnRetVal = false;
//Add code to test these values later
return blnRetVal;
}
public string R31
{
get
{
return this.R31Field;
}
set
{
this.R31Field = value;
}
}
public string R32
{
get
{
return this.R32Field;
}
set
{
this.R32Field = value;
}
}
}
public partial class requestBodyR4
{
private string R41Field;
public string R41
{
get
{
return this.R41Field;
}
set
{
this.R41Field = value;
}
}
}
现在唯一的问题是缺少xmlns =“ http://www.Test.com/MyClass”>
如果我将以下代码添加到名称空间部分:
ns.Add("", "http://www.test.com/Myclass");
如果大小写与名称空间MyClass相同,我会得到我需要的输出,但是NOTICEi不得不改变字母之一的大小写以获取输出,然后它就不会输出。
提前致谢
命名空间为MyClass,元素名称为Req。 因此,您需要定义命名空间。
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("MyClass", "http://www.test.com/myclass");
并调用带有XmlSerializerNamespaces实例的Serialize重载。 然后,Request类本身就是一个名为Req的Element。
[XmlRoot(Namespace = "http://www.test.com/myclass", ElementName = "Req")]
public class Request
{
[XmlElement("R1", Namespace = "")]
public string R1 { get; set; }
public bool ShouldSerializeR1() { return !string.IsNullOrWhiteSpace(R1); }
[XmlAttribute("schemaLocation", Namespace = "")]
public string xsiSchemaLocation = "http://www.test.com/myclass.xsd";
}
可以通过声明为Xml属性的属性来添加schemaLocation。 可以通过使用ShouldSerialize * MyLovelyPropertyName()*语法的方法来控制是否应序列化属性。
