反序列化XML無效操作異常

我想反序列化和使用xsd.exe工具創建的對象的xml文件。當我嘗試運行示例應用程序時，出現以下異常：InvalidOperationException - XML文檔（1，1）中存在錯誤。我在這裏做錯了什麼？這裏是我的代碼：反序列化XML無效操作異常

示例XML文件

<?xml version="1.0" encoding="utf-8"?> 
<patient> 
<pr> 
<fname>Cindy </fname> 
<lname>Knapp </lname> 
<id>1 </id> 
</pr> 
<pr> 
<fname>Regie </fname> 
<lname>Miller </lname> 
<id>2 </id> 
</pr> 
<ad> 
    <id>1</id> 
    <streetnumber>1200 NW</streetnumber> 
    <city>Miami </city> 
    <state>FL</state> 
    <zip>34488</zip> 
</ad> 
<ad> 
    <id>2</id> 
    <streetnumber>1299 NE</streetnumber> 
    <city>NY </city> 
    <state>NY</state> 
    <zip>9032</zip> 
</ad> 
</patient>

這裏是產生

在主函數類，我試圖反序列化的XML文件。

class Program 
    { 
     static void Main(string[] args) 
     { 
      patient pr = new patient(); 
      XmlSerializer serializer = new XmlSerializer(typeof(patient)); 
      FileStream myStream = new FileStream(@"C:\com\dss\VXReports\XSD Document\EXAMPLE.CS", FileMode.Open); 
      pr = (patient)serializer.Deserialize(myStream); 
      string kr = string.Empty; 
     } 
    } 

Stack Trace:

「C：\ COM \ DSS \ VXReports \ XSD文件\ EXAMPLE.CS」 - 「的.cs」是一個不同尋常的擴展XML文件。 – 2014-09-03 00:14:17

@AlexeiLevenkov，這是問題。我花了4個多小時試圖弄清楚代碼有什麼問題，而且我甚至沒有注意到文件名後面的.cs擴展名。謝謝。 – user3802347 2014-09-03 00:58:43

訣竅是注意異常消息。這不是騙你。請記住，「一旦你消除了不可能的事物，無論如何，儘管不可能，是事實。因此，即使您的XML文檔看起來很完美，您對XML序列化程序的輸入也不是有效的XML文檔。這意味着您完美的XML文檔不是XML序列化程序的輸入... – 2014-09-03 02:03:56

我將文件擴展名從.cs更改爲.xml。我還在該項目中創建了一些部分類，併爲這些類添加了一些XML裝飾。使用xsd.exe自動生成的類中沒有任何更改。我的主類

static void Main(string[] args) 
     { 
      patient pr = new patient(); 
      XmlSerializer serializer = new XmlSerializer(typeof(patient)); 
      FileStream myStream = new FileStream(@"C:\com\dss\VXReports\XSD Document\EXAMPLE.XML", FileMode.Open); 
      pr = (patient)serializer.Deserialize(myStream); 
      string kr = string.Empty; 
     }

新的部分類：

[Serializable, XmlRoot("patient")] 
    public partial class patient 
    { 
     [XmlElement("pr")] 
     public patientPR[] pr { get; set; } 
     [XmlElement("ad")] 
     public patientAD[] ad { get; set; } 
    } 

    [Serializable, XmlType("pr")] 
    public partial class patientPR 
    { 
     [XmlElement("fname")] 
     public string fname { get; set; } 
     [XmlElement("lname")] 
     public string lname { get; set; } 
     [XmlElement("id")] 
     public int id { get; set; } 
    } 

    [Serializable, XmlType("ad")] 
    public partial class patientAD 
    { 
     [XmlElement("id")] 
     public int id { get; set; } 
     [XmlElement("streetnumber")] 
     public string streetnumber { get; set; } 
     [XmlElement("city")] 
     public string city { get; set; } 
     [XmlElement("state")] 
     public string state { get; set; } 
     [XmlElement("zip")] 
     public ushort zip { get; set; } 
    }

您的代碼對我來說工作得很好。如果您在XML中具有該功能，請從頂部刪除「示例XML文件」。如果你沒有那個，你可能會遇到一些問題，如不可見的字符或者編碼衝突。在SO上查看此鏈接，例如：Deserialization error in XML document(1,1)
