在异常和返回值之间选择

我创建了一个从文件中解析一些文档的类.

I have created a class that parses some document from file.

class Parser
{
  public Parse(string fileName)
  {
    ///
  }
}

在这种情况下，有时可能会出现解析错误返回某些数据.我为此创建了特殊课程.

Sometimes there can be parsing errors in that case parser has to return certain data. I have created special class for that.

class ParsingError
{
 // some data
}

我该如何正确处理此类错误.我至少有两个选择:

How can I correctly deal with such errors. I have at least two options:

创建我自己的异常或返回值.

create my own exception or return value.

选项一

myParser.Parse(fileName, out error);

方案二

try
{
  myParser.Parse(fileName)
}

catch(MyParsingException ex)
{
  // use ex.Error field
}

更新

如果我没记错的话，异常背后的思想是它应该处理一些异常的东西，那是一些方法不打算处理的情况.

If I am not mistaken the ideology behind the exception is that it should deal with something exceptional, that is some situation that the method is not intended to deal with.

这让我想知道例如:

解析器在文件中发现未知字段，或者编码错误

这会被视为特例吗?
