c# - XML 文档中的错误 (2,2)

Question

我有一些 xml 文件，我正尝试在给定代码中按以下方式反序列化。

using (StreamReader srFileContent = new StreamReader(filePath))  
{
    XmlSerializer serializer = new XmlSerializer(typeof(messageType));   
    messageType objMessage = (messageType)serializer.Deserialize(srFileContent);  
}

这里的file locate at filePath不包含以下几行

<?xml version="1.0"?>
<message xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">

这就是我收到错误的原因。你能帮我在反序列化给定文件的流之前如何添加这行运行时吗？

错误如下:

System.InvalidOperationException: There is an error in XML document (2, 2). ---> System.InvalidOperationException: was not expected. at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReadermessageType.‌​Read161_message() --- End of inner exception stack trace --- at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events) at System.Xml.Serialization.XmlSerializer.Deserialize(TextReader textReader) at CCR2BB.frmMain.BWConvertProcess_DoWork()

您必须查看基本异常才能找出问题所在。捕获的异常可能包含 4 个或更多内部异常。

如:

try
{
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.GetBaseException());
}
