[Resolved] ReadAllBytes fails reading 1GB file

When I try to create a byte array to read a file that's 1GB in size, I get System.OutOfMemoryException. I assume this means there isn't enough system memory to allocate an array of bytes this large.

Is there some other way I can read this file, possibly in chunks, to deal with it?

Code:

---

System.IO.FileInfo fi = new System.IO.FileInfo(txtRead.Text);
byte[] bt;

try
{
    bt = new byte[fi.Length];
    bt = System.IO.File.ReadAllBytes(txtRead.Text);
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message);
}

What do you want to do with the file?
your code and your question explains nothings

Create a FileStream object and call it's Read method:

Code:

---

const int BUF_SIZE = 1024;
System.IO.FileStream fs = new System.IO.FileStream("file path here", 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();
