如何通过.net向xslt传递参数？
以下是《ASP.NET v2.0 XML编程指南》中的示例，可是运行时总是报错：“因为安全原因，此 XML 文档中禁用 DTD。要启用 DTD 处理，将 XmlReaderSettings 上的 ProhibitDtd 属性设置为 false，并将该设置传递给 XmlReader.Create 方法。”请问该如何修改？

<%@ Page Language= "C# " %>
<%@ Import Namespace= "System.Xml " %>
<%@ Import Namespace= "System.Xml.Xsl " %>
<%@ Import Namespace= "System.Xml.XPath " %>

<script runat= "server ">

void Page_Load(object sender, System.EventArgs e)
{
string xmlPath = Server.MapPath( "aboutus.xml ");
string xslPath = Server.MapPath( "aboutus.xsl ");

XPathDocument xpathDoc = new XPathDocument(xmlPath);
XslCompiledTransform transform = new XslCompiledTransform();
XsltArgumentList argsList = new XsltArgumentList();
argsList.AddParam( "discount ", " ", ".15 ");
//Load the XSL stylsheet into the XslCompiledTransform object
transform.Load(xslPath);
transform.Transform(xpathDoc, argsList, Response.Output);
}

</script>

错了,

string xslPath = Server.MapPath( "aboutus.xsl ");

XPathDocument xpathDoc = new XPathDocument(xmlPath);
XmlReaderSettings settings = XmlReaderSettings(xslPath);
settings.ProhibitDtd = true;
XslCompiledTransform transform = new XslCompiledTransform();
XsltArgumentList argsList = new XsltArgumentList();
argsList.AddParam( "discount ", " ", ".15 ");
//Load the XSL stylsheet into the XslCompiledTransform object
