如何将浮点数组转换为字节数组?

how can I convert a float array to Byte array?

推荐答案

这称为序列化.您显然需要将二进制序列化为用于许多目的的字节数组.您需要使用类System.BitConverter， http://msdn.microsoft.com/en- us/library/system.bitconverter.aspx [ ^ ].

它允许您使用GetBytes(Single)或GetBytes(Double)将单个float元素转换为字节.
要完成整个操作，您首先需要使用GetBytes(Int32)序列化float数组的长度，然后序列化循环中的所有float成员并将它们串联在一起(例如，使用Array.Copy).立即创建长度为sizeof(Int32) + ArrayLength*sizeof(Double)(或sizeof(Single))的结果数组.

您可能需要纠正匹配的反序列化方法-从字节数组到浮点数组(使用ToInt32，ToDouble或ToSingle).

This is called serialization. You apparently need binary serialization into array of bytes used for many purposes. You need to use the class System.BitConverter, http://msdn.microsoft.com/en-us/library/system.bitconverter.aspx[^].

It allows you to convert to byte a single float element using GetBytes(Single) or GetBytes(Double).

To do the whole thing, you need first serialize the length of the float array using GetBytes(Int32), then serialize all float members in loop and concatenate all together (for example, use Array.Copy). Pre-create the resulting array at once with the length sizeof(Int32) + ArrayLength*sizeof(Double) (or sizeof(Single)).

You will probably need to right a matching deserialization method — from array of byte to array of float (using ToInt32, ToDouble or ToSingle).
