十六进制转32位浮点型(整型)

        string hexString = "000FB5E0";

        int num = int.Parse(hexString, System.Globalization.NumberStyles.AllowHexSpecifier);

        byte[] floatVals = BitConverter.GetBytes(num);

        float f = BitConverter.ToSingle(floatVals, 0);

        //Int32 f = BitConverter.ToInt32(floatVals, 0);

        Response.Write(GetGMTDateTime(f).ToShortDateString() + " " + GetGMTDateTime(f).ToLongTimeString());
