問(wèn)題描述

我正在嘗試獲取架構(gòu)并針對(duì)我的 xml 進(jìn)行驗(yàn)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 閱讀器 = XmlReader.Create(xml, settings);

我明白了

無(wú)效的URI:Uri字符串太長(zhǎng)System.UriFormatException 未處理 Message=Invalid URI: Uri 字符串太長(zhǎng).源 = 系統(tǒng)堆棧跟蹤:在 System.Uri.CreateThis(字符串 uri，布爾值 dontEscape，UriKind uriKind)在 System.Uri..ctor(字符串 uriString，UriKind uriKind)在 System.Xml.XmlResolver.ResolveUri(Uri baseUri，字符串 relativeUri)在 System.Xml.XmlUrlResolver.ResolveUri(Uri baseUri，字符串 relativeUri)在 System.Xml.XmlReaderSettings.CreateReader(字符串 inputUri，XmlParserContext inputContext)在 System.Xml.XmlReader.Create(字符串 inputUri，XmlReaderSettings 設(shè)置，XmlParserContext inputContext)在 System.Xml.XmlReader.Create(字符串 inputUri，XmlReaderSettings 設(shè)置)在 Program.cs:line 42 中的 ConsoleApplication2.Program.Main(String[] args)在 System.AppDomain._nExecuteAssembly(RuntimeAssembly 程序集，字符串 [] 參數(shù))在 System.AppDomain.ExecuteAssembly(字符串 assemblyFile，證據(jù) assemblySecurity，String [] args)在 Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly()在 System.Threading.ThreadHelper.ThreadStart_Context(對(duì)象狀態(tài))在 System.Threading.ExecutionContext.Run(ExecutionContext executionContext，ContextCallback 回調(diào)，對(duì)象狀態(tài)，布爾 ignoreSyncCtx)在 System.Threading.ExecutionContext.Run(ExecutionContext executionContext，ContextCallback 回調(diào)，對(duì)象狀態(tài))在 System.Threading.ThreadHelper.ThreadStart() 內(nèi)部異常:

不告訴我最大長(zhǎng)度是多少或任何東西.以前有人收到過(guò)這個(gè)嗎?

如果參數(shù)是字符串，問(wèn)題是你的 xmlreader.create 函數(shù)中的 xml 應(yīng)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(gè) msdn 文檔 XmlReader.Create 方法對(duì)于不同的重載方法..

我猜你應(yīng)該使用 TextReader 之一.p>

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);

I get

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

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

eg.

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

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

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

I am guessing you should use the TextReader one.

這篇關(guān)于無(wú)效的 URI:Uri 字符串太長(zhǎng)的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
