异常详细信息: System.NotSupportedException: 不支持给定路径的格式。源错误: 
 行 36:         settings.ValidationType = ValidationType.Schema;
行 37:         //把XSD添加到xmlreaderSettings 的Schmas 模式中
行 38:         settings.Schemas.Add(null,XmlReader.Create(xsdPath));//????????????
行 39:         reader = XmlReader.Create(xmlPath,settings);
行 40:         while (reader.Read())  源文件: c:\Inetpub\wwwroot\Chapter5\a.aspx.cs   I 行: 38功能：用XSD模式验证xml数据
程序如下：
public partial class a : System.Web.UI.Page
{
    //对CHAR有自动扩展的功能    private StringBuilder _builder = new StringBuilder();
    protected void Page_Load(object sender, EventArgs e)
    {
       
        //httpRequest.page.Request 获取页面请求的对象
        
        string xmlPath = Request.PhysicalApplicationPath + @"C:\Inetpub\wwwroot\Chapter5\Author.xml";        string xsdPath = Request.PhysicalApplicationPath + @"C:\Inetpub\wwwroot\Chapter5\Author.xsd";
        XmlReader reader = null;
        XmlReaderSettings settings = new XmlReaderSettings();
        //set prooperty
        settings.ValidationEventHandler += new ValidationEventHandler(this.ValidationEventHandler);
        settings.ValidationType = ValidationType.Schema;
        //把XSD添加到xmlreaderSettings 的Schmas 模式中
        settings.Schemas.Add(null,XmlReader.Create(xsdPath));//????????????这句有问题
        reader = XmlReader.Create(xmlPath,settings);
        while (reader.Read())
        { 
            //   
        }
        if (_builder.ToString() == String.Empty)
        {
            Response.Write("Validate complated successfully");
        }
        else
        {
            Response.Write("validate failed " + _builder.ToString());
        }    }    public void ValidationEventHandler(object sender ,ValidationEventArgs args) 
    {
        _builder.Append("error!" +args.Message +"</br>");
    }
}
