对象未设置为实例...视觉工作室是否在拖我？ [英] Object not set to an instance... Is visual studio trolling me?

问题描述

我得到了通常的错误，但这是应该发生的行：

Hi,

I get the usual error but this is the line it's supposed to occur on:

public string Serialize()
{
  var serializer = new XmlSerializer(GetType()); //<<< This line
  TextWriter writer = new StringWriter();
  serializer.Serialize(writer, this);

  return writer.ToString();
}

我看不出这有什么意义。我的调试器无法展开，但我检查了QuickWatch中的值。该行上的任何内容都不为null，但是我再也看不到该行上的内容可以为null，可以吗？



这不是我第一次已经看过这个，但现在每次都在发生：S



我有什么想法可以继续吗？



谢谢^ _ ^

I don't see how that makes any sense. My debugger is unable to unwind but I have checked the values in QuickWatch. Nothing on that line is null, but then again I can't see what on that line can be null, can it?

This isn't the first time I've seen this but now it's happening every time :S

Any ideas how I can proceed?

Thanks ^_^

推荐答案

听起来像是一些奇怪的行为。你可以在下面的代码中检查这个的类型吗？在vs中放置一个断点并检查thisType是什么。也许它给出了一个线索。

Sounds like some strange behaviour. Could you check the type of this like in the code below? Put a breakpoint in the vs and check out what thisType is. Maybe it gives a clue.

public string Serialize()
{
  Type thisType = this.GetType();
  [BREAKPOINT] var serializer = new XmlSerializer(thisType); //<<< This line
  TextWriter writer = new StringWriter();
  serializer.Serialize(writer, this);

  return writer.ToString();
}

祝你好运！

Good luck!
