Currently used data file growth is not reflected by FileInfo.Length

The FileInfo.Length
property in C# returns the size of the file in bytes at the time it was accessed. If the file size has changed since you last accessed it, the property won't reflect the current size.
If you want to get the updated size of the file, you should refresh the FileInfo
object before accessing the Length
property. You can do this using the Refresh
method. Here's an example:
csharpusing System;
using System.IO;
class Program
{
static void Main()
{
string filePath = "path/to/your/file.txt";
FileInfo fileInfo = new FileInfo(filePath);
// Get the initial file size
long initialFileSize = fileInfo.Length;
Console.WriteLine($"Initial File Size: {initialFileSize} bytes");
// Some time passes, and the file size changes
// For example, you write more data to the file.
// Refresh the FileInfo object to get the updated file size
fileInfo.Refresh();
// Get the updated file size
long updatedFileSize = fileInfo.Length;
Console.WriteLine($"Updated File Size: {updatedFileSize} bytes");
}
}
By calling fileInfo.Refresh()
, the FileInfo
object will update its internal state to reflect the current state of the file on disk, and fileInfo.Length
will give you the updated file size.
