有OptionalField被废弃，在C＃中？ [英] Have OptionalField been obsoleted in C#?

问题描述

看来，<一个href="http://msdn.microsoft.com/en-us/library/system.runtime.serialization.optionalfieldattribute.aspx"相对=nofollow> OptionalFieldAttribute 是不再（如果有的话）需要序列化的BinaryFormatter。

It seems that the OptionalFieldAttribute is not longer (if ever) needed for serialization with BinaryFormatter.

随着例如，从codeguru 有不再建造code在Visual Studio 2010时抛出的异常，针对旧版本的.NET框架时也是如此。

With a example from codeguru there is no longer any exception thrown when building the code in Visual Studio 2010, even when targeting older versions of the .NET framework.

计算器上的另一个问题表明，它一直都是可选的。这是真的？如果是这样，有其实并没有什么办法让一个例外，缺少现场，序列化二进制内容时，在.NET？

Another question on stackoverflow suggests that it's always been optional. Is this true? And if so, is there actually not any way to get a exception for a missing field, when serializing to binary content in .NET?

推荐答案

要得到的异常，这个语句添加到反序列化code：

To get the exception, add this statement to the deserialization code:

        formatter.AssemblyFormat = FormatterAssemblyStyle.Full;
