将float转换为其二进制表示形式(使用MemoryStream?) [英] Convert float to its binary representation (using MemoryStream?)

问题描述

我想将给定的float转换为其二进制表示形式.我试图将浮点值写入MemoryStream，逐字节读取此MemoryStream，然后将字节转换为二进制表示形式.但是每次尝试都失败了.

I'd like to convert a given float into its binary representation. I tried to write the float value into a MemoryStream, read this MemoryStream byte by byte and convert the bytes into their binary representation. But every attempt failed.

• 无法读取关闭的视频流"(但我只关闭了作家)
• 出于测试目的，我只写了一个整数(我认为是四个字节)，当不刷新StreamWriter时，MemoryStream的长度为0，而当我刷新时，其长度为1.

• "Can't read closed stream" (but I only closed the writer)
• For test purposes I simply wrote an integer (I think four bytes in size) and the length of the MemoryStream was 0, when I didn't flush the StreamWriter, and 1, when I did.

我敢肯定有一种更好的方法可以将float转换为二进制，但是我还想了解一些有关MemoryStream类的信息.

I'm sure there is a better way to convert floats to binary, but I also wanted to learn a little bit about the MemoryStream class.

推荐答案

您可以使用 BinaryWriter.Write(float) .目前尚不清楚您之前使用MemoryStream做了什么，但是您不想想要使用StreamWriter-这是用于文本的.

You can use BitConverter.GetBytes(float) or use a BinaryWriter wrapping a MemoryStream and use BinaryWriter.Write(float). It's not clear exactly what you did with a MemoryStream before, but you don't want to use StreamWriter - that's for text.
