如何在ASP.NET中向客户端发送大型XML。NET有效?

HttpContext上下文-当前HttpContext。

简单的解决方案:

context.Response.Write(xmlResponse.OwnerDocument.OuterXml);

但是当XML真的很大时,我们可以在那一行得到OutOfMemoryException。 调用堆栈看起来像:

   at System.String.GetStringForStringBuilder(String value, Int32 startIndex, Int32 length, Int32 capacity)
   at System.Text.StringBuilder.GetNewString(String currentString, Int32 requiredLength)
   at System.Text.StringBuilder.Append(Char value)
   at System.IO.StringWriter.Write(Char value)
   at System.Xml.XmlTextWriter.InternalWriteEndElement(Boolean longFormat)
   at System.Xml.XmlTextWriter.WriteFullEndElement()
   at System.Xml.XmlElement.WriteTo(XmlWriter w)
   at System.Xml.XmlElement.WriteContentTo(XmlWriter w)
   at System.Xml.XmlElement.WriteTo(XmlWriter w)
   at System.Xml.XmlElement.WriteContentTo(XmlWriter w)
   at System.Xml.XmlElement.WriteTo(XmlWriter w)
   at System.Xml.XmlDocument.WriteContentTo(XmlWriter xw)
   at System.Xml.XmlDocument.WriteTo(XmlWriter w)
   at System.Xml.XmlNode.get_OuterXml()

我会写一些这样的代码:

HttpWriter writer = new HttpWriter(context.Response);
XmlTextWriter xmlWriter = new XmlTextWriter(writer);
xmlResponse.OwnerDocument.WriteTo(xmlWriter);

但问题是HttpWriter的构造函数是内部的!HttpContext在Write方法内部使用HttpWriter。
