c# – 使用“using”关键字时会被处置的内容

我们举个例子：

using (var someObject = new SomeObject())
{
    var someOtherObject = new SomeOtherObject();
    someOtherObject.someMethod(); 
}

SomeOtherObject还实现了Idisposable.
当SomeObject被处置时,SomeOtherObject也会被处理掉吗？ SomeOtherObject会发生什么？
(在SomeObject的dispose方法中没有实现处理SomeOtherObject)

解决方法

不会.只会处理using子句中的字段.在你的情况下只有someObject.

基本上代码被翻译成了

var someObject = null;
try
{
  someObject = new SomeObject()

  var someOtherObject = new SomeOtherObject();
  someOtherObject.someMethod(); 
}
finally
{
  if (someObject != null )
  someObject.dispose()
}
