C#實體類生成XML與XML Schema文檔。本站提示廣大學習愛好者：（C#實體類生成XML與XML Schema文檔）文章只能為提供參考，不一定能成為您想要的結果。以下是C#實體類生成XML與XML Schema文檔正文
一、實體類生成XML
1 private void CreateXML()
2 {
3 Type[] objType = DBEntityRegst();
4 foreach (var item in objType)
5 {
6 if (item == null)
7 {
8 break;
9 }
10
11 XmlDocument doc = new XmlDocument();
12
13 //<?xml version="1.0"?>
14 XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "", "");
15 doc.AppendChild(dec);
16
17 //創建一個根節點
18 //<schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
19 XmlElement root = doc.CreateElement("schema");
20 root.SetAttribute("xmlns:xs", "http://www.w3.org/2001/XMLSchema");
21 doc.AppendChild(root);
22
23 //<element Name="DTO_BatchTotal">
24 XmlElement element1 = doc.CreateElement("element");
25 element1.SetAttribute("Name", (item.Name).ToString());
26
27 //<complexType>
28 XmlElement element2 = doc.CreateElement("complexType");
29
30 //<sequence>
31 XmlElement element3 = doc.CreateElement("sequence");
32
33
34 System.Reflection.PropertyInfo[] ps = item.GetProperties();
35 for (int i = 0; i < ps.Length; i++)
36 {
37 string typeold = (ps[i].PropertyType).ToString();
38 string[] a = typeold.Split('.');
39 string typenew = ("xs:" + a[1]).ToLower();
40
41 //<element Name="batch" Type="xs:string" />
42 //<element Name="total" Type="xs:decimal" />
43 XmlElement element4 = doc.CreateElement("element");
44 element4.SetAttribute("Name", ps[i].Name);
45 element4.SetAttribute("Type", typenew);
46
47 //給element3添加子節點
48 element3.AppendChild(element4);
49 }
50 //同上
51 element1.AppendChild(element2);
52 element2.AppendChild(element3);
53 root.AppendChild(element1);
54
55 XmlSerializerNamespaces xsn = new XmlSerializerNamespaces();
56 xsn.Add("xs", "http://www.w3.org/2001/XMLSchema");
57 doc.Save(@"E:\XML\" + item.Name.ToString() + ".xml");
58
59
60 }
61 }
62
63 /// <summary>
64 /// 將DTO實體加載到List列表
65 /// </summary>
66 private Type[] DBEntityRegst()
67 {
68
69 List<IEntityRegstHelper> entityRegstHelperlist = null;
70 entityRegstHelperlist = new List<IEntityRegstHelper>();
71 var classes = Assembly.Load("ZxSoftERPGC.Model").GetTypes();//命名空間[Model]下的類類型集
72
73 Type[] a = new Type[classes.Length];
74 int i = 0;
75 foreach (var classtype in classes)
76 {
77
78 if (((classtype.Name).ToString()).Contains("DTO_")) //指定獲取類名包含“DTO_”的類
79 {
80 a[i] = classtype;
81 i++;
82 }
83 }
84 return a;
85 }
結果如：
<?xml version="1.0"?>
<schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<element Name="DTO_BatchTotal">
<complexType>
<sequence>
<element Name="batch" Type="xs:string" />
<element Name="total" Type="xs:decimal" />
</sequence>
</complexType>
</element>
</schema>

二、生成XML Schema
private void button1_Click(object sender, EventArgs e)
{
Type[] objType = DBEntityRegst();
foreach (var item in objType)
{
if (item == null)
{
break;
}
XmlSchema schema = new XmlSchema();
// <xs:element name="">
XmlSchemaElement elementPets = new XmlSchemaElement();
schema.Items.Add(elementPets);
elementPets.Name = (item.Name).ToString();
// <xs:complexType>
XmlSchemaComplexType complexType = new XmlSchemaComplexType();
elementPets.SchemaType = complexType;
//<xs:sequence>
XmlSchemaSequence seqauth = new XmlSchemaSequence();
complexType.Particle = seqauth;
System.Reflection.PropertyInfo[] ps = item.GetProperties();
for (int i = 0; i < ps.Length; i++)
{
// <xs:element name=""/>
XmlSchemaElement catRef = new XmlSchemaElement();
seqauth.Items.Add(catRef);
catRef.Name = ps[i].Name;
string typeold = (ps[i].PropertyType).ToString();
string[] a = typeold.Split('.');
string typenew = (a[1]).ToLower();
//類型格式轉換
if (typenew == "int32" || typenew == "int64")
{
typenew = "integer";
}
if (typenew == "datetime")
{
typenew = "date";
}
catRef.SchemaTypeName = new XmlQualifiedName(typenew, "http://www.w3.org/2001/XMLSchema");
}
XmlSchemaSet schemaSet = new XmlSchemaSet();
schemaSet.Add(schema);
schemaSet.Compile();
XmlSchema compiledSchema = null;
foreach (XmlSchema schema1 in schemaSet.Schemas())
{
compiledSchema = schema1;
}
XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable());
nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
//用流的形式輸出保存
using (MemoryStream stream = new MemoryStream())
{
compiledSchema.Write(stream, nsmgr);
FileStream fs = new FileStream(@"E:\XML\" + item.Name.ToString() + ".xml", FileMode.Create);
BinaryWriter w = new BinaryWriter(fs);
w.Write(stream.ToArray());
fs.Close();
stream.Close();
}
}
}
結果如：
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="DTO_BatchTotal">
<xs:complexType>
<xs:sequence>
<xs:element name="batch" type="xs:string" />
<xs:element name="total" type="xs:decimal" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

2種生成都是用實體集批量生成，單個實體就不用演示了吧。
