Array in struct

Feb 10th, 2007

I have this C++ code :

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
    const int ANYSIZE_ARRAY = 1;
    struct LUID {DWORD LowPart; WORD HighPart;};
    struct LUID_AND_ATTRIBUTES {LUID Luid; DWORD Attributes;};
    struct TOKEN_PRIVILEGES {DWORD PrivilegeCount;   LUID_AND_ATTRIBUTES Privileges[ANYSIZE_ARRAY];};
    const int ANYSIZE_ARRAY = 1;
    struct LUID {DWORD LowPart; WORD HighPart;};
    struct LUID_AND_ATTRIBUTES {LUID Luid; DWORD Attributes;};
    struct TOKEN_PRIVILEGES {DWORD PrivilegeCount;   LUID_AND_ATTRIBUTES Privileges[ANYSIZE_ARRAY];};

I want to convert this code into C# syntax.

I tried this one, but don't know how to place array in a struct.

    const int ANYSIZE_ARRAY = 1;
    struct LUID {Int32 LowPart; Int16 HighPart;};
    struct LUID_AND_ATTRIBUTES {LUID Luid; Int32 Attributes;};
    struct TOKEN_PRIVILEGES {Int32 PriviligeCount; /*WHAT TO WRITE HERE??*/};
    const int ANYSIZE_ARRAY = 1;
    struct LUID {Int32 LowPart; Int16 HighPart;};
    struct LUID_AND_ATTRIBUTES {LUID Luid; Int32 Attributes;};
    struct TOKEN_PRIVILEGES {Int32 PriviligeCount; /*WHAT TO WRITE HERE??*/};

Help me please.

Hi

Would it not be something like;

LUID_AND_ATTRIBUTES Privileges[ANYSIZE_ARRAY];

for the above i have assumed that, you want an array of LUID_AND_ATTRIBUTES type struct , which you have defined before, as comprising of LUID Luid; int32 Attributes.
If my assunption is wrong, then please accept my apologies.

HTH

Thanks

Given error :

Exactly. What I try to do is place an array into a struct. I couldn't find an example not even in google.

This one doesn't work :

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
struct Animals { float Bird; int Rabbit[20]; Int64 Elephant; };
struct Animals { float Bird; int Rabbit[20]; Int64 Elephant; };

Error 1 Syntax error, bad array declarator. To declare a managed array the rank specifier precedes the variable's identifier. To declare a fixed size buffer field, use the fixed keyword before the field type. C:\Prog\SAVE\C#\Shutdown\Main.cs 35 42 Shutdown
Error 2 Array size cannot be specified in a variable declaration (try initializing with a 'new' expression) C:\Prog\SAVE\C#\Shutdown\Main.cs 35 43 Shutdown

This one too :

struct Animals { float Bird; int[20] Rabbit; Int64 Elephant; };
struct Animals { float Bird; int[20] Rabbit; Int64 Elephant; };

Error 1 Array size cannot be specified in a variable declaration (try initializing with a 'new' expression) C:\Prog\SAVE\C#\Shutdown\Main.cs 35 36 Shutdown

Another one :

struct Animals { float Bird; int Rabbit[]; Int64 Elephant; };
struct Animals { float Bird; int Rabbit[]; Int64 Elephant; };
