為什么我收到InvalidOperationException？

Question

我有這個代碼：

private string mConfigFileName = "configData.xml";

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

我在線上使用斷點mConfiguration = (Configuration)XmlUtility.Deserialize(mConfiguration.GetType(), mConfigFileName); 它會采用這種方法：

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;
        }      

然后就行Object data = xs.Deserialize(xmlReader); 它正在跳回到Getconfiguration方法的問題：

catch 
            {
                mConfiguration = new Configuration();
            }

例外：

XML文檔中存在錯誤（0,0）

這是xml文檔內容：

<?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>

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

這是完整的異常消息：

編輯：

我將xml文件作為文件添加到我的項目資源中。 並改為代碼：

private string mConfigFileName = Properties.Resources.configData;

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

現在它再次跳到了捕獲，但有一個不同的例外：

Answer 1

找不到文件'D：\\ C-Sharp \\下載文件\\下載 - 文件 - 項目 - 版本-012 \\下載文件\\ bin \\ x86 \\ Release \\ configData.xml'

檢查該文件是否確實存在。 如果它包含在解決方案中，請檢查是否將內容設置為編譯類型，將復制到輸出文件夾設置為“如果更新”。
