Implementing Memcpy in C#

[Vidya Bhagwath]

Hello Experts,
I am porting a c++ code into c#.There are 3 structures, as explained
below.
typedef struct
{
unsigned char ByteCount;
unsigned short RegVals[10];
} WRITE_INFO;

typedef struct
{
unsigned short VarAddress;
unsigned short data[256];
}USER_PASSED_INFO;

typedef struct
{
WRITE_INFO WriteRegInfo;
USER_PASSED_INFO UserPassedInfo;
}LINKINFO;

LINKINFO Info;

My code uses the memcpy in the following fashion.

memcpy(Info.WriteRegInfo.RegVals[2], &Info.UserPassedInfo.data[2],
Info.WriteRegInfo.ByteCount );

As I know there is no code for memcpy in the C#. So how can I port the
above code into the C#. I am new to C#. I don't know much regarding
the C#. So can anybody tell me how exactly I can implement the above
line of code in C#.
Thanks in Advance for any help.
Regards,
Vidya

There is no need to use structures for this in C#, use classes.
You can use Array.Copy to copy sections from one array to another.

memcpy(Info.WriteRegInfo.RegVals[2], &Info.UserPassedInfo.data[2],

Info.WriteRegInfo.ByteCount );

simply Info.UserPassedInfo.Data[2] = Info.WriteRegInfo.RegVals[2]
should do the trick in C#, I believe
(assuming Info.UserPassedInfo.Data is an array of the same type as
RegVals[2])

Hai All,
I was sucessfully able to port the code
"memcpy(Info.WriteRegInfo.RegVals[2], &Info.UserPassedInfo.data[2],
Info.WriteRegInfo.ByteCount )" into Visual C#.NET by following your
suggestions.Thank you very much for your guidance.
