无效的URI:Uri字符串太长

Question

我正在尝试获取模式并验证我的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);

我明白了

不告诉我最大长度是什么或任何东西.以前有人得过这个吗？

问题是如果参数是字符串,xmlreader.create函数中的xml应该是uri.

例如.

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.

看看这个msdn doc XmlReader.Create方法, 用于不同的重载方法..

我猜你应该使用TextReader.
