“ throw”和“ throw ex”之间有区别吗？

是，有一点不同;

• throw ex

  重置堆栈跟踪（因此您的错误似乎源自

  HandleException

  ）

• throw

  不会-原罪犯将得到保留。

  static void Main(string[] args)

  {
  try
  {
  Method2();
  }
  catch (Exception ex)
  {
  Console.Write(ex.StackTrace.ToString());
  Console.ReadKey();
  }
  }
  
  

  private static void Method2()
  {
  try
  {
  Method1();
  }
  catch (Exception ex)
  {
  //throw ex resets the stack trace Coming from Method 1 and propogates it to the caller(Main)
  throw ex;
  }
  }

  private static void Method1()
  {
  try
  {
  throw new Exception(“Inside Method1”);
  }
  catch (Exception)
  {
  throw;
  }
  }
