How to check if a file is writtable?

How to check if a file is writtable?

• AndersBank

  Hi,

  You can use the following code segment

  string FilePath = @"C:\TEST.txt";
  System.IO.FileInfo Info = new System.IO.FileInfo(FilePath);
  if (!Info.IsReadOnly)
  {
  Console.WriteLine("FILE IS WRITABLE");
  }

  Hi

  System.IO.FileInfo fi = new System.IO.FileInfo(@"C:\abc.txt");

  if (System.IO.FileAttributes.ReadOnly == fi.Attributes)

  {

  //The file is read only.

  }

  //OR

  if (fi.IsReadOnly)

  {

  //In 2005 The File is read only

  }

  I tried:

  if ((File.GetAttributes(azmanStoreFileName) & FileAttributes.ReadOnly) != 0

  but gave me error, saying

  The given path's format is not supported.

  Can anyone help Thanks

  Hi,

  You can use the following code segment

  string FilePath = @"C:\TEST.txt";
  System.IO.FileInfo Info = new System.IO.FileInfo(FilePath);
  if (Info.IsReadOnly)
  {
  Console.WriteLine("FILE IS READ-ONLY");
  }

  try to implement following code

  FileAttributes fa = File.GetAttributes(fileName);

  if(fa.ToString().IndexOf(FileAttributes.ReadOnly.ToString()) > -1 )

  MessageBox.Show("ReadOnly");

  Hi,
  
  I tried your code..and it worked for me. Here's what I wrote:
  
  static void Main(string[] args)
  {
  string azmanStoreFileName = @"C:\Test.txt";
  if ((File.GetAttributes(azmanStoreFileName) & FileAttributes.ReadOnly) != 0)
  Console.WriteLine("readonly");
  Console.ReadLine();
  }
  
  Make sure you wrote everything correct. It should work.
  
  Maheshwari's code should also work fine. As an alternative, you can also try this:
  
  static void Main(string[] args)
  {
  FileInfo file = new FileInfo(@"C:\test.txt");
  
  // Console.WriteLine(file.Attributes.ToString());
  if ((file.Attributes & FileAttributes.ReadOnly) ==
  FileAttributes.ReadOnly)
  {
  Console.WriteLine("File is read-only (correct test).");
  }
  
  Console.ReadLine();
  }
  
  Hope that helps,
  Ashish

  if the file is Archive then the file is writtable.

  FileAttributes fa = File.GetAttributes(fileName);

  if (fa.ToString() == FileAttributes.Archive.ToString())

  MessageBox.Show("Writtable");
