[Resolved] ReadAllBytes fails reading 1GB file

[wey97]

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?

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);
}
