Question

我有这段代码：

private string mConfigFileName = "configData.xml";

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

我在第mConfiguration = (Configuration)XmlUtility.Deserialize(mConfiguration.GetType(), mConfigFileName);行使用断点，它将使用此方法：

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;
        }

然后在Object data = xs.Deserialize(xmlReader);行上它跳回到Getconfiguration方法的捕获：

catch 
            {
                mConfiguration = new Configuration();
            }

例外：

XML文档（0,0）中存在错误

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>

  <MagnifierWidth>150</MagnifierWidth>
  <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项目的资源中。并改为代码：

private string mConfigFileName = Properties.Resources.configData;

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

现在它再次跳到了捕获区，但有一个不同的例外：

Answer 1

无法找到文件'D：\ C-Sharp \ Download 文件\下载 - 文件 - 项目 - 版本-012 \下载文件\ BIN \ 86 \推出\ configData.xml'

检查文件是否确实存在。如果它包含在解决方案中，请检查是否将内容设置为编译类型，将复制到输出文件夹设置为“如果更新”。

为什么我收到InvalidOperationException？
