I am using this code
string location1 = textBox2.Text;
byte[] bytes = File.ReadAllBytes(location1);
string text = (Convert.ToBase64String(bytes));
richTextBox1.Text = text;
But when I use a file that is too big I get out of memory exception.
I want to use File.ReadAllBytes
in chunks. I have seen code like this below
System.IO.FileStream fs = new System.IO.FileStream(textBox2.Text, System.IO.FileMode.Open);
byte[] buf = new byte[BUF_SIZE];
int bytesRead;
// Read the file one kilobyte at a time.
do
{
bytesRead = fs.Read(buf, 0, BUF_SIZE);
// 'buf' contains the last 1024 bytes read of the file.
} while (bytesRead == BUF_SIZE);
fs.Close();
}
But I don't know how to actually convert the bytesRead
into a byte array which I will convert to text.
EDIT: Answer found. Here is the code!
private void button1_Click(object sender, EventArgs e)
{
const int MAX_BUFFER = 2048;
byte[] Buffer = new byte[MAX_BUFFER];
int BytesRead;
using (System.IO.FileStream fileStream = new FileStream(textBox2.Text, FileMode.Open, FileAccess.Read))
while ((BytesRead = fileStream.Read(Buffer, 0, MAX_BUFFER)) != 0)
{
string text = (Convert.ToBase64String(Buffer));
textBox1.Text = text;
}
}
To change the readable bytes which are in text format, create a new byte and make it equal
(Convert.FromBase64String(Text)). Thanks everyone!
