英文:
Convert DWORD to float and float to DWORD
问题
我从浮点数到DWORD的转换结果如下：
float f = 2.4f;
Uint32 value = BitConverter.ToUInt32(BitConverter.GetBytes(f), 0);
Console.WriteLine("{0:D}", value); // 1075419546
我想要从DWORD，1075419546，转换成浮点数，2.4f。我该如何实现这个转换？
英文:
I got the conversion result from float to DWORD like below.
float f = 2.4f;
Uint32 value = BitConverter.ToUInt32(BitConverter.GetBytes(f), 0);
Console.WriteLine("{0:D}", value); // 1075419546
And I would like to get conversion from DWORD,1075419546 to float,2.4f.
How can I get this?

Finally, I made it. Please refer to below if you need.
UInt32 value = 1075419546;
string hexString = value.ToString("X8");
byte[] floatBytes = Enumerable.Range(0, hexString.Length).Where(x => x % 2 == 0).Select(x => Convert.ToByte(hexString.Substring(x, 2), 16)).ToArray();
Array.Reverse(floatBytes);
float floatValue = BitConverter.ToSingle(floatBytes, 0);
Console.WriteLine("{0:F}", floatValue);
