驗證Xml針對Xsd Schema的錯誤

我有以下Xml，我想根據Xsd Schema進行驗證（以下）。我想使用下面給出的C＃函數來針對給定的Xsd Schema驗證Xml。我收到這種通用類錯誤消息「根級數據無效，第1行，第1位」。這發生在「while（vr.Read（））」。驗證Xml針對Xsd Schema的錯誤

你能解釋一下這個問題的原因和解決方法是什麼，或者有什麼辦法可以解決這些類型的通用錯誤。

正如您從我的Xsd模式可以看到的，它也具有對其他子xsd文件的引用。我想知道它是否與錯誤有關。

親切問候

以下是C＃驗證功能：

      string schemaNamespace, string schemaUri) 
    { 
     // Continue? 
     if(xml == null || schemaNamespace == null || schemaUri == null) 
     { 
      return false; 
     } 

     isValidXml = true; 
     XmlValidatingReader vr; 
     XmlTextReader tr; 
     XmlSchemaCollection schemaCol = new XmlSchemaCollection(); 
     schemaCol.Add(schemaNamespace, schemaUri); 

     try 
     { 
      // Read the xml. 
      tr = new XmlTextReader(xml); 
      // Create the validator. 
      vr = new XmlValidatingReader(tr); 
      // Set the validation tyep. 
      vr.ValidationType = ValidationType.Schema; 
      // Add the schema. 
      if(schemaCol != null) 
      {

AFAIK XmlValidatingReader已過時。我想你會更好地使用XmlReader。爲了控制URI解決方案（如果模式引用了其他方案作爲相對路徑），您可以通過從XmlUrlResolver繼承並重寫ResolveUri方法來創建自己的XML URL解析器類。然後將其分配給XmlReaderSettings類的XmlResolver成員。不過，我希望事情不會惡化，但希望:)這裏是我可以建議的原理圖代碼：

  XmlTextReader reader = new XmlTextReader(pathToXSD); 
      XmlSchema schema = XmlSchema.Read(reader,  ValidationEventHandler); 
      XmlReaderSettings settings = new XmlReaderSettings(); 

      settings.ValidationType = ValidationType.Schema; 
      settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema; 
      settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation; 
      settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings; 
      settings.ValidationEventHandler += new ValidationEventHandler(ValidationEventHandler); 
      settings.Schemas.Add(schema); 

      using (StringReader xmlStream = new StringReader(xml)) 
      { 
       using (XmlReader xmlReader = XmlReader.Create(xmlStream, settings)) 
       { 
        while (xmlReader.Read()) { } 
       } 
      }
