我现在要找到问题的根源。 我们没有例外处理,因此,对错误来自何地进行猜测。 这里我的问题是,如果一种方法能够回收XmlTextReader物体,如果该方法在审判/捕获中包装,最终被封块使用的是Close()方法,则该物体是否无效?
如果是的话,我如何妥善处置这些资源,我知道有没有一种Clone()或Copy()方法,是否还有另一种方法可以做到这一点? 我是否甚至应该注意处置XmlTextReader和XmlReader物体?

在将<条码>XmlReader退回打电话之前,不得关闭或处分。
没有,Dispose
//Close
没有将null
转让给物体,它们只是要求该物体释放它认为需要释放的任何资源。
XmlReader GetReader()
{
XmlRead reader = ....
// DO NOT dispose/close reader here with
// reader.Dispose() or using(reader){...}
return reader;
}
使用:
using(var reader = GetReader()) {...}
请注意,在<代码>Dispose之后,许多类型的数据保障不得查阅。 许多班级采用的方法。 净额是不能用后,请标注>Dispose。
