Question Converting nested C structure to C# Is this possible?

Question

I have a struct written in C that I want to use in C#. It uses an array of structures nested inside of another structure. This is very straightforward in C but I have been unsuccessful in duplicating this simple example. Is this even possible using C#? If it is not possible what other options do I have?

Here is the C code simplified. The actual structure is much more complex.

// -- Message File Structure -- 

        struct message_struct{       // Message Structure 

           char mname[20];             // Message Name 

           char mattr;                 // Message Slot Used flag 

           struct {    // Page             // Page Structure 

              int  duration;         // Duration 

              char stext[201];       // Scroll Buffer 

              struct { // Line         // Line Structure 

                 char csize;         // Char Size 

                 char mchar[31];      // Line Characters 

              } mline[8];            // # of Lines 

           } mpage[10];                 // # of Pages 

        } message;   

Then to access the structure
message.mpage[0].mline[0].mchar[0] = 'A';
