如何使用XSD文件验证输入c＃对象？ [英] How to validate input c# object using XSD file?

问题描述

您好，



我想使用我定义的xsd文件验证我的输入对象。你能告诉我怎么做吗？



以下是我的c＃对象

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

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; }
    }
}

下面是序列化输入对象后得到的XML

below is the XML I get after serializing my input object

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

以下是XSD文件我使用输入对象生成

Below is the XSD file I generated using the input object

<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>

正如您在XSD中看到的，我有TestId，SocialSecurityNo ，FirstName和LastName或必填字段以及OrgSelection和MiddleName或可选字段..



所以如果我在不传递FirstName和LastName的情况下验证我的输入对象，我应该看到验证错误..



有人可以帮忙吗？

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?

推荐答案

嗨Ravindranath.net，



您可以使用验证扩展方法对XSD验证XML。



以下是显示如何操作的代码。

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.

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>

此代码可能需要一些自定义满足您的要求。希望这会有所帮助。

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