Well, I am relatively new in C#, and I have a 2 classes. The first class has a public struct and the second one is trying to declare the struct. I am not good enough in english, but this is the code so that you may understand :

First Class :

class PE{
#region NT Headers

[StructLayout(LayoutKind.Explicit)]
public struct IMAGE_NT_HEADERS32
{
    [FieldOffset(0)]
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 4)]
    public char[] Signature;

    [FieldOffset(4)]
    public IMAGE_FILE_HEADER FileHeader;

    [FieldOffset(24)]
    public IMAGE_OPTIONAL_HEADER32 OptionalHeader;
}

[StructLayout(LayoutKind.Explicit)]
public struct IMAGE_NT_HEADERS64
{
    [FieldOffset(0)]
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 4)]
    public char[] Signature;

    [FieldOffset(4)]
    public IMAGE_FILE_HEADER FileHeader;

    [FieldOffset(24)]
    public IMAGE_OPTIONAL_HEADER64 OptionalHeader;
}
#endregion
}

Second Class :

class Main
{
struct NT_Header
    {
        Namespace.PE.IMAGE_NT_HEADERS32 INTSIGN = new Namespace.PE.IMAGE_NT_HEADERS32(); //HERE IS THE ERROR!
    }
}

It always raises the error... Thanks for helps!

Just to save you a bunch of time: Reading the Portable Executable (PE) Header in C# – Jonathon Reinhart Dec 22 '12 at 2:53
Certainly, though, the compiler gives you a line number pointing you right to where the error is? Why have you omitted this, making it harder for us to help you? – Jonathon Reinhart Dec 22 '12 at 2:53
yeah, but i just want to declare it in the second class, because i need it.. – newbie Dec 22 '12 at 2:54
it has an error at the main class, declaring the INTSIGN @Jontathon Reinhart – newbie Dec 22 '12 at 2:55

You can't assign a default value to a struct field, like you're doing in NT_Header. It's not legal C#. This would compile:

class Main
{
struct NT_Header
    {
        public Namespace.PE.IMAGE_NT_HEADERS32 INTSIGN;
    }
}
