C# deserializing a binary structure with bitfields - how to do?

I have a C struct that is defined in a way similar to this:

struct TestStruct
{
    uint flag1 :2;
    uint flag2 :2;
    uint flag3 :2;
    uint flag4 :2;

    uint value1;
} TestStruct;

I know that I can deserialize a binary struct by using the 开发者_运维百科StructLayout attribute and Marshal.PtrToStructure(). But is there a way to do this with binary fields as shown in the structure where one value is just 2 bits long?

Thanks in advance.

There is no direct support for such a structure in C#. You have to use an integral type holding all the bits and extract the fields from it afterwards.
