Hello,

I would like to validate my input object using the xsd file I defined. Would you please let me know how to do this?

below is my c# object

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace BaseModel
{
    public class Test
    {
        public string TestID { get; set; }

        public string SocialSecurityNo { get; set; }

        public string OrgSelection { get; set; }

        public string FirstName { get; set; }

        public string MiddleName { get; set; }

        public string LastName { get; set; }
    }
}

below is the XML I get after serializing my input object

XML

<?xml version="1.0" encoding="utf-8" ?>
<Personnel>
  <EnterpriseID>1</EnterpriseID>
  <SocialSecurityNo>12345678</SocialSecurityNo>
  <OrgSelection/>
  <MiddleName/>
  <LastName>Tharigopula</LastName>
</Personnel>

Below is the XSD file I generated using the input object

XML

<xs:schema elementformdefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="Personnel" nillable="true" type="Personnel" />
  <xs:complextype name="Test">
    <xs:sequence>
      <xs:element minoccurs="1" maxoccurs="1" name="TestID" type="xs:string" />
      <xs:element minoccurs="1" maxoccurs="1" name="SocialSecurityNo" type="xs:string" />
      <xs:element minoccurs="0" maxoccurs="1" name="OrgSelection" type="xs:string" />
      <xs:element minoccurs="1" maxoccurs="1" name="FirstName" type="xs:string" />
      <xs:element minoccurs="0" maxoccurs="1" name="MiddleName" type="xs:string" />
      <xs:element minoccurs="1" maxoccurs="1" name="LastName" type="xs:string" />
    </xs:sequence>
  </xs:complextype>
</xs:schema>

As you can see in the XSD, I have the TestId, SocialSecurityNo, FirstName, and LastName or the mandatory fields and OrgSelection and MiddleName or optional fields..

so if I were validate my input object without passing the FirstName and LastName, I should see the validation errors..

Can someone please help?

Hi Ravindranath.net,

You can validate a XML against a XSD using the Validate extension method.

Here is the code showing how to do it.

C#

XmlSchemaSet schemaSet = new XmlSchemaSet();
DirectoryInfo dir = new DirectoryInfo("<path where="" you="" have="" your="" xsd="" files="">");

 foreach (FileInfo fileInfo in dir.GetFiles("*.xsd"))
 {
     schemaSet.Add(null, fileInfo.FullName);
 }
 XDocument docToValidate = XDocument.Load("<path of="" xml="" you="" want="" to="" validate="">");
 string validationMessage = string.Empty;
 docToValidate.Validate(schemaSet, (o, e) =>
 {
     validationMessage += e.Message + Environment.NewLine;
 });
 return validationMessage;</path></path>

This code may need some customization to meet your requirements. Hope this helps.
