B64 Substring

Simon

Hello

I've managed to encode an image file to base64 using
"convert.ToBase64String"
I know you cannot send the whole string to the server, but you need to send
so many char's at a time which i think is about 76. Is there a way in which
i can do this?
The whole base64 string is in the varible "b64String" but i wish to send 76
chars at a time. I know i can use the substring function but the code i'm using doesn't work, any advance or help?

int size = b64String.Length;
int csize = 0;
string chunky;

while (csize < size + 1)
{
chunky = b64String.Substring(csize, 76);
csize = csize + 76;
Console.Write(chunky);
}

Thanks

Si

Change your code like this:

int size = b64String.Length;

int csize = 0;

int diff=0;

string chunky;

while (csize < size )

{

if(size-csize>=76)

{

chunky = b64String.Substring(csize, 76);

csize = csize + 76;

}

else

{

diff=size-csize;

chunky = b64String.Substring(csize, diff);

csize = csize + diff;

}

Console.Write(chunky);

}
