C # Save Streamwriter after every 200 cycles without closing

I am using StreamWriter to write some data to a file.

System.IO.StreamWriter file = new System.IO.StreamWriter(path);
while(something_is_happening && my_flag_is_true)
     file.WriteLine(some_text_goes_Inside);

file.close();

What I noticed is that until the close is called, no data is written to the file.

Is there a way to preserve the contents of the file before closing.

For this purpose, you can use the Flush method.

System.IO.StreamWriter file = new System.IO.StreamWriter(path);
int counter = 0;
while(something_is_happening && my_flag_is_true)
{
    file.WriteLine(some_text_goes_Inside);
    counter++;
    if(counter < 200) continue;
    file.Flush();
    counter = 0;
}
file.Close();

I think you are looking for Flush .

file.Flush();


must do the trick.

Call Flush()

to force buffers to write:

file.Flush();

Clears all buffers for the current author and causes any buffered data to be written to the underlying stream.

Or set the AutoFlush property

file.AutoFlush = true;

Gets or sets a value indicating whether the StreamWriter will flush its buffer into the underlying stream after each call to StreamWriter.Write.

Cycle:

System.IO.StreamWriter file = new System.IO.StreamWriter(path);
for (int i = 0; true && flag; i++)
{
    file.WriteLine(some_text_goes_Inside);
    if (i == 200)
    {
        file.Flush();
        i = 0;
    }
}
file.Close();
