convert array of bytes to int or float

[mcklsn]

How do you convert an array of bytes to an int or a float?. I'm reading in binary bytes of data from a file. I have to take them 4 at a time, reverse their order (because they come in "wrong endian&quot, and then combine them into a single int or a single float. I know how to do everything but that last step. Any help would be appreciated.

you should use Convert.toInteger(array);
or Integer.parse...
or convert it to string then to integer

I have a more complicated problem than I thought. I have 4 byte (32 bit) floating point numbers in a file with the 4 bytes in the wrong order. I can read each byte into an int32, then, by shifting them the appropriate number of places, OR them all together to form a single int32 with the bit pattern for the float in it. I then need to have C# recognize this int32 as a float, NOT convert it to a float. If it converts it, then the 32-bit pattern is assumed to be an integer and the integer value is converted to a float. This is not what I need.
This is easy to do in Java using the Float.IntBitsToFloat method, but there is no equivalent method in .Net. Does anybody know how the do this in C#?
Thanks

Instead of reading them into an int, read them into a byte array. You can put them into the byte array in the correct order and then convert the byte array into whatever data type you need:

byte[] input = new byte[4]; // 32-bit byte array

// put your bytes into the array in correct order

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

If you must use an int to read them in, just change the first line to:

byte[] input = BitConverter.GetBytes( /* your int here */ );

Let us know if that helps.

Thanks a lot. That did the trick. I appreciate the help.
