.NET : LINQ TO XML中进行XML文件验证

using System;
using System.Xml.Schema;
using System.Xml.Linq;

//LINQ TO XML中，通过对System.Xml.Schema的扩展实现了简单方便的架构验证功能

string xmlFile = "..\\..\\OrderData.xml";
string xsdFile = "..\\..\\OrderSchema.xsd";

XmlSchemaSet schemas = new XmlSchemaSet();
schemas.Add("", xsdFile);

XDocument doc = XDocument.Load(xmlFile);

bool error=false;
doc.Validate(schemas, (o, e) =>
    {
        Console.WriteLine("验证文档发生错误:{0}", e.Message);
        error = true;
    });
Console.WriteLine("文档是否通过验证{0}?", !error);

doc.Root.Element("Orders").Element("Order").Element("CustomerID").Value = "AAAAA";//故意修改该文档
//因为架构中规定了Orders中的CustomerID必须先存在于Customers中，所以，这样修改之后会出错

doc.Validate(schemas, (o, e) =>
{
    Console.WriteLine("验证文档发生错误:{0}", e.Message);
    error = true;
});
Console.WriteLine("文档是否通过验证{0}?", !error);
Console.Read();
