在我正在处理的代码中,有一些属性被序列化。据我所知,所有这些都工作得很好,但只有一个。代码如下:
// Fields that the properties use.
private bool _useAlertColors = false;
private List<Int32> _colorArgb = new List<Int32>(new Int32[]{Color.White.ToArgb(), Color.Yellow.ToArgb(), Color.Red.ToArgb()});
// The one that does not work.
public List<Color> AlertColors
{
get
{
List<Color> alertColors = new List<Color>();
foreach (Int32 colorValue in _colorArgb)
{
alertColors.Add(Color.FromArgb(colorValue));
}
return alertColors;
}
set
{
// If there's any difference in colors
// then add the new color
for (int i = 0; i < _colorArgb.Count; i++)
{
if (_colorArgb[i] != value[i].ToArgb())
{
_colorArgb[i] = value[i].ToArgb();
HasChanged = true;
}
}
}
}
// One of those that work.
public bool UseAlertColors
{
get
{
return _useAlertColors;
}
set
{
if (_useAlertColors != value)
{
_useAlertColors = value;
HasChanged = true;
}
}
}
// Serializing method.
public bool Serialize(string filePath)
{
if (string.IsNullOrEmpty(filePath))
{
Logger.Log("Can't save settings, empty or null file path.");
return false;
}
FileStream fileStream = null;
try
{
fileStream = new FileStream(filePath, FileMode.Create);
FilePath = filePath;
System.Xml.Serialization.XmlSerializerFactory xmlSerializerFactory =
new XmlSerializerFactory();
System.Xml.Serialization.XmlSerializer xmlSerializer =
xmlSerializerFactory.CreateSerializer(typeof(Settings));
xmlSerializer.Serialize(fileStream, this);
Logger.Log("Settings have been saved successfully to the file " + filePath);
}
catch (ArgumentException argumentException)
{
Logger.Log("Error while saving the settings. " + argumentException.Message);
return false;
}
catch (IOException iOException)
{
Logger.Log("Error while saving the settings. " + iOException.Message);
return false;
}
finally
{
if (fileStream != null)
fileStream.Close();
}
return true;
}
序列化后,这就是我最终得到的结果:
<UseAlertColors>true</UseAlertColors>
<AlertColors>
<Color />
<Color />
<Color />
</AlertColors>
AlertColors
属性有什么问题?为什么没有连载?
编辑:我已相应地更改了 AlertColors
属性,但它仍然不起作用:
public List<int> AlertColors
{
get
{
return _colorArgb;
}
set
{
// If there's any difference in colors
// then add the new color
for (int i = 0; i < _colorArgb.Count; i++)
{
if (_colorArgb[i] != value[i])
{
_colorArgb[i] = value[i];
HasChanged = true;
}
}
}
}
我在 .xml 文件中得到的是这样的:
<AlertColors>
<int>-1</int>
<int>-8355840</int>
<int>-65536</int>
</AlertColors>
这是初始化 _colorArgb
字段时设置的第一个值。我可以在程序执行过程中看到字段发生变化,但是当覆盖属性被序列化时,它会使用底层字段的初始值进行序列化。
是什么导致了这个问题?
最佳答案
XMLSerializer 在序列化时仅使用类的公共(public)属性 - Color 类没有。
这是一个如何解决这个问题的好例子:http://www.codeproject.com/Articles/2309/NET-XML-Serialization-a-settings-class
关于c# - XML 序列化程序无法处理属性,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/13044886/
