Convert byte to enum by Marshalling IntPtr

Question

I'm trying to convert a byte array of size 1 to an enum:

public enum InformationMessageLevel : byte
{
    Information = 0,
    Warning = 1,
    Error = 2,
    Fatal = 3
}

Using marshalling:

   // bytes = byte[1] = 0
   // t is typeof(InformationMessageLevel)
unsafe
{
    fixed (byte* p = bytes)
    {
        var localPtr = p;

        return Marshal.PtrToStructure((IntPtr)localPtr, t);
    }
}

But I get the error:

"The specified structure must be blittable or have layout information.\r\nParameter name: structure"

The reason I'm using marshaling with an IntPtr, is this method is used to unserialize data dynamically to properties of different types.

Answer 1

A dynamic solution without using marshaling:

byte[] bytes = { 0 };
var t = typeof(InformationMessageLevel);
var result = Enum.ToObject(t, bytes[0]);

Console.WriteLine(result);

Output:

Information
