为什么我得到InvalidOperationException？

Question

我有这样的代码：

private string mConfigFileName = "configData.xml"; 

     private void GetConfiguration() 
     { 
      try 
      {     
       mConfiguration = (Configuration)XmlUtility.Deserialize(mConfiguration.GetType(), mConfigFileName);     
      } 
      catch 
      { 
       mConfiguration = new Configuration(); 
      } 
     } 

我使用就行了mConfiguration = (Configuration)XmlUtility.Deserialize(mConfiguration.GetType(), mConfigFileName);一个断点，这将这个方法：

public static Object Deserialize(Type type, string fileName) 
     { 
      XmlSerializer xs = new XmlSerializer(type); 

      XmlTextReader xmlReader = new XmlTextReader(fileName); 
      Object data = xs.Deserialize(xmlReader); 

      xmlReader.Close(); 

      return data; 
     }  

然后上线Object data = xs.Deserialize(xmlReader);它跳回的抓该方法Getconfiguration：

catch 
      { 
       mConfiguration = new Configuration(); 
      } 

例外：

有XML文档中的错误（0，0）

这是XML文档内容：

<?xml version="1.0" encoding="utf-8"?> 
<Configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <LocationX>877</LocationX> 
    <LocationY>498</LocationY> 
    <CloseOnMouseUp>true</CloseOnMouseUp>

    <MagnifierHeight>150</MagnifierHeight> 
    <ZoomFactor>3</ZoomFactor> 
    <SpeedFactor>0.35</SpeedFactor> 
</Configuration> 

这是完整的异常消息：

编辑：

我将xml文件作为文件添加到我的项目资源中。 而改为代码：

private string mConfigFileName = Properties.Resources.configData; 

     private void GetConfiguration() 
     { 
      try 
      {     
       mConfiguration = (Configuration)XmlUtility.Deserialize(mConfiguration.GetType(), mConfigFileName);     
      } 
      catch 
      { 
       mConfiguration = new Configuration(); 
      } 
     } 

现在它有一个不同的异常再次跳到陷阱：

Answer 1

Could not find file 'D:\C-Sharp\Download File\Downloading-File-Project-Version-012\Downloading File\bin\x86\Release\configData.xml'

检查文件是否确实存在。如果它包含在解决方案中，请检查是否将Content设置为编译类型，并将Copy to Output文件夹设置为“If Newer”。
