无效URI: URI字符串太长

本文关键字：URI 无效 字符串 | 更新日期: 2023-09-27 18:05:18

我正在尝试抓取一个模式并对我的xml进行验证。

  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);

我得到

没有告诉我最大长度是多少。有人以前听过吗?

无效URI: URI字符串太长

问题在于xmlreader中的XML。如果参数是字符串，则Create函数应该是uri。

。

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

在您的情况下，xml文件被解释为url，因此它抱怨限制。

查看msdn doc XmlReader。创建方法对于不同的重载方法…

我猜你应该使用TextReader的一个。
