Can I cast to a [Flags] enum?

I have an enum variable. Is there some way to cast an int or BitArray
and get my enum value? I have to communicate with an old C-style
sever so I get an array of bits("0","1"). But I'm using an enum
variable to store the data.

[Flags]
public enum LaneCapabilities
{
MLT = 0,
ACM = 1,
AVI = 2,
ATIM = 4,
Degraded = 8,
CCS = 16
}

Ended up with this code:

string[] flags = ReadRTMessage().Split(' ');

LaneCapabilities capable = new LaneCapabilities();
for( int i = 0; i<flags.Length; i++)
{
switch(i)
{
case 0 :
if (flags[0] == "1")
capable |= LaneCapabilities.ACM;
break;
case 1 :
if (flags[1] == "1")
capable |= LaneCapabilities.ATIM;
break;
case 2:
if (flags[2] == "1")
capable |= LaneCapabilities.AVI;
break;
case 3:
if (flags[3] == "1")
capable |= LaneCapabilities.CCS;
break;
case 4:
if (flags[1] == "1")
capable |= LaneCapabilities.Degraded;
break;
case 5:
if (flags[1] == "5")
capable |= LaneCapabilities.MLT;
break;
}
}

Seems like a lot of work for a .NET app. Any suggestions?

Dwight,

The underlying type of an enumeration (if the type isn't explicitly
specified) is an integer (System.Int32). This means that enumeration
values and integer values are interchangeable via casting:

LaneCapabilities capable = (LaneCapabilities) 12;

// capable.ATIM and capable.Degraded are "set".
