在c＃中将字节数组转换为整数
问题描述：
float input = 25;
byte[] buffer = BitConverter.GetBytes(input);
缓冲区包含0x00 0x00 0xc8 0x41。我需要将它转换回浮点数，即25.我只知道十六进制值，请告诉我怎么做。
buffer contains 0x00 0x00 0xc8 0x41.I need to convert it back to float i.e 25.I knows only hex values,Please tell how to do it.
答
BitConverter.ToSingle [ ^ ]方法？
eg
What's wrong with BitConverter.ToSingle[^] method?
e.g.
float input = 25;
byte[] buffer = BitConverter.GetBytes(input);
float output = BitConverter.ToSingle(buffer,0);
