使用(object obj = new Object())是什么意思？

Question

这个陈述在C#中意味着什么？

        using (object obj = new object())
        {
            //random stuff
        }

Answer 1

这意味着obj工具IDisposible将在using块之后被妥善处理.它的功能与以下相同:

{
  //Assumes SomeObject implements IDisposable
  SomeObject obj = new SomeObject();
  try
  {
    // Do more stuff here.       
  }
  finally
  { 
    if (obj != null)
    {
      ((IDisposable)obj).Dispose();
    }
  }
}

Answer 2

using (object obj = new object())
{
    //random stuff
}

相当于:

object obj = new object();
try 
{
    // random stuff
}
finally {
   ((IDisposable)obj).Dispose();
}
