Best way to make a file writeable in c#

Question

I'm trying to set flag that causes the `Read Only` check box to appear when you `right click \ Properties` on a file. Thanks!

Accepted Answer

Two ways:

```
System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath);
fileInfo.IsReadOnly = true/false;
```

or

```
// Careful! This will clear other file flags e.g. `FileAttributes.Hidden`
File.SetAttributes(filePath, FileAttributes.ReadOnly/FileAttributes.Normal);
```

The `IsReadOnly` property on `FileInfo` essentially does the bit-flipping you would have to do manually in the second method.
