How to write to external file using one boolean bit a time.

Hi Tom,

Your buffer size is 1 , but your tring to write 32 bits.. So u r getting that error.

here is my code

static void Main(string[] args)
{
bool tif = true;
byte[] buffer = BitConverter.GetBytes(tif);
FileInfo ap = new FileInfo("tempii.txt");
string filePath = ap.FullName;
string destinationPath = Path.Combine("C:\\check", Path.GetFileName(filePath));
using (Stream output = File.OpenWrite(destinationPath))
{
int bits = 32;
while (bits > 0)
{
for (int i = 1; i < 33; i++)//4 random bytes
{
if (tif == true)
{
tif = false;
goto A;
}
if (tif == false) tif = true;
A:;
output.Write(buffer, 0, 1);
}
}
}

See the below syntax for Stream.Write from msdn

public abstract void Write(
byte[] buffer,
int offset,
int count
)

here ,

buffer: Type: System.Byte[]
An array of bytes. This method copies count bytes from buffer to the current stream.

offset: Type: System.Int32
The zero-based byte offset in buffer at which to begin copying bytes to the current stream.

count: Type: System.Int32
The number of bytes to be written to the current stream.
