我试图抓住一个模式并验证我的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);
我得到
Invalid URI: The Uri string is too long
System.UriFormatException was unhandled Message=Invalid URI: The Uri string is too long. Source=System StackTrace:

不告诉我最大长度是什么或什么.以前有人得过吗？
解决方法
问题是,如果参数是一个字符串,xmlreader.create函数中的xml应该是一个uri.
例如.
XmlReader reader = XmlReader.Create("http://ServerName/data/books.xml",settings);
在你的情况下,xml文件被解释为url,因此它正在抱怨极限.
看看这个msdn doc XmlReader.Create Method
对于不同的重载方法
我猜你应该使用TextReader.
