MORE INFORMATION

Steps to reproduce the behavior

1. Start Microsoft Visual Studio .NET.
2. On the File menu, point to New, and then click Project.
3. Under Project Types, click Microsoft Visual C# .NET or Microsoft Visual Basic .NET. Under Templates, click Console Application.
4. Name the project MyTestConsoleApplication, and then click OK.
5. Replace the existing code with the following code:
   
   Visual C# .NET Code

   using System;
   using System.IO;
   using System.Xml;
   using System.Xml.Schema;
   
   namespace MyNameSpace
   {
      public class MyClass
      {
         // This method (Main) reads the XML file by using the XmlSchema class
         // and then writes the XML Schema on the Console.
         public static void Main(string []args)
         {
            try 
            {
               // Read the XML Schema file by using the XmlTextReader class.
               XmlTextReader reader = new XmlTextReader(@"..\..\Test.xsd");
               XmlSchema myXmlSchema = XmlSchema.Read(reader, null);
               reader.Close();
   
               // Write the XML Schema file to the Console.
               myXmlSchema.Write(Console.Out);
               Console.Write("\n\n\n\nPress ENTER to quit .....");
               Console.Read();
               Console.WriteLine("");
            }
            catch (Exception e) 
            {
               // Catch exceptions, if any exist.
               Console.WriteLine(e);
               Console.Write("\n\n\n\nPress ENTER to quit .....");
               Console.Read();
               Console.WriteLine("");
            }
         }
      }
   }
   

   Visual Basic .NET Code

   Imports System
   Imports System.IO
   Imports System.Xml
   Imports System.Xml.Schema
   
   Module Module1
      'This method (Main) reads the XML file by using the XmlSchema class
      'and then writes the XML Schema on the Console.
      Sub Main()
         Try
            ' Read the XML Schema file by using the XmlTextReader class.
            Dim reader As New XmlTextReader("..\Test.xsd")
            Dim myXmlSchema As XmlSchema
            myXmlSchema = myXmlSchema.Read(reader, Nothing)
            reader.Close()
   
            ' Write the XML Schema file to the Console.
            myXmlSchema.Write(Console.Out)
            Console.WriteLine("")
            Console.Write("Press ENTER to quit .....")
            Console.Read()
            Console.WriteLine("")
         Catch e As Exception
            Console.WriteLine(e)
            Console.Write("Press ENTER to quit .....")
            Console.Read()
            Console.WriteLine("")
         End Try
      End Sub
   End Module
   

6. In Solution Explorer, right-click MyTestConsoleApplication, click Add, and then click Add New Item.
7. Under Categories, click Local Project Items. Under Templates, click XML Schema.
8. Name the schema file Test.xsd, and then click Open.
9. Right-click the Test.xsd page, and then click View XML Source.
10. Replace the existing XML Schema code with the following code:

    <?xml version="1.0" encoding="utf-8" ?>
    <xs:schema xmlns:mstns="http://tempuri.org/Dataset1.xsd" 
    xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" 
    xmlns:NameSpace1="http://tempuri.org/XMLSchema1.xsd" 
    xmlns="http://tempuri.org/Dataset1.xsd" attributeFormDefault="qualified" 
    elementFormDefault="qualified" targetNamespace="http://tempuri.org/Dataset1.xsd" 
    id="Dataset1" xmlns:xs="http://www.w3.org/2001/XMLSchema">
       <xs:import namespace="http://tempuri.org/XMLSchema1.xsd" />
       <xs:element msdata:IsDataSet="true" name="Dataset1">
          <xs:complexType>
             <xs:choice maxOccurs="unbounded">
                <xs:element name="Table" type="NameSpace1:Famous_x0020_People" />
             </xs:choice>
          </xs:complexType>
       </xs:element>
    </xs:schema>
    <xs:schema xmlns="http://tempuri.org/XMLSchema1.xsd" elementFormDefault="qualified" 
    targetNamespace="http://tempuri.org/XMLSchema1.xsd" id="XMLSchema1" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
       <xs:complexType name="Famous_x0020_People">
          <xs:sequence>
             <xs:element minOccurs="0" name="Name" type="xs:string" />
             <xs:element minOccurs="0" name="Role" type="xs:string" />
             <xs:element minOccurs="0" name="BirthDate" type="xs:date" />
          </xs:sequence>
       </xs:complexType>
    </xs:schema>

11. On the Debug menu, click Start.
    
    In the Console output, you may find

     <xs:element name="Table" type="NameSpace1:Famous_x005F_x0020_People" />

    instead of

    <xs:element name="Table" type="NameSpace1:Famous_x0020_People" />
