无效的URI：URI字符串太长 [英] Invalid URI: The Uri string is too long

问题描述

我试图抓住一个架构和验证对我的XML。

I am trying to grab a schema and validate against my xml.

  XmlReaderSetting settings = new System.Xml.XmlReaderSettings();
            settings.Schemas.Add(null, "http://example.com/myschema.xsd");
            settings.ValidationEventHandler += new System.Xml.Schema.ValidationEventHandler(settings_ValidationEventHandler); 
            settings.ValidationType = ValidationType.Schema;
            settings.IgnoreWhitespace = false;
            XmlReader reader = XmlReader.Create(xml, settings);

我收到

不告诉我是什么最大长度或任何东西。有谁拿到过？

Does not tell me what the max length is or anything. Anyone ever get this before?

推荐答案

的问题是，在你的xmlreader.create功能的XML应该是一个URI，如果该参数是一个字符串。

the problem is that the xml in your xmlreader.create function should be a uri if the argument is a string.

如：

XmlReader reader = XmlReader.Create("http://ServerName/data/books.xml", settings);

在你的情况下，XML文件将被PTED作为URL跨$ P $，因此它是抱怨的限制。

In your case the xml file is being interpreted as the url and hence it is complaining about the limit.

看看这个MSDN文档 XmlReader.Create方法 针对不同的重载方法。

look at this msdn doc XmlReader.Create Method for different overloaded methods..

我猜你应该使用的TextReader 之一。
