The result is as follows:

<?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>

Ii. Generate XML Schema

Private void button#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 (); // Type format conversion 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 "); // Output and save 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 ();}}}

The result is as follows:

<?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>

The two types of generation are all generated in batches using the entity set. You don't need to demonstrate a single entity.
