Question

I wanted to write a code in C# to list all the users/groups having access (Read/Write/Full) to a shared folder on a server.

For Example: I have a shared folder \servername\MyData. Now I wanted to list the users/groups who have access to this folder.

This should get you pointed in the right direction, I can’t test it atm but should be something similar.

private bool CheckAccess(DirectoryInfo directory)
{

    // Get the collection of authorization rules that apply to the current directory
    AuthorizationRuleCollection acl = directory.GetAccessControl().GetAccessRules(true, true, typeof(System.Security.Principal.SecurityIdentifier));

    foreach (var rule in acl)
    {
        // do something here
    }
}
