無效的 URI：Uri 字符串太長

Question

我正在嘗試獲取架構並針對我的 xml 進行驗證。

  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

不告訴我最大長度是多少或任何東西。 以前有人得到這個嗎？

問題是，如果參數是字符串，則 xmlreader.create function 中的 xml 應該是 uri。

例如。

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

在您的情況下， xml 文件被解釋為 url ，因此它抱怨限制。

看看這個msdn doc XmlReader.Create Method以了解不同的重載方法。

我猜你應該使用TextReader之一。
