[c#] Pass in an enum as a method parameter

I have declared an enum:

public enum SupportedPermissions
{
    basic,
    repository,
    both
}

I also have a POCO like this:

public class File
{
    public string Id { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public SupportedPermissions SupportedPermissions { get; set; }      
}

Now I would like to create a method that I can use to create a new File object with:

public string CreateFile(string id, string name, string description, Enum supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions.basic
    };

    return file.Id;
}

How would I create the parameter for the enum and how would I assign that like in my pseudo code SupportedPermissions = supportedPermissions.basic so that my File instance has a SupportedPermissions set to it?

public string CreateFile(string id, string name, string description, SupportedPermissions supportedPermissions)
{
    file = new File
    {  
       Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions
    };

    return file.Id;
}

First change the method parameter Enum supportedPermissions to SupportedPermissions supportedPermissions.

Then create your file like this

file = new File
{  
    Name = name,
    Id = id,
    Description = description,
    SupportedPermissions = supportedPermissions
};

And the call to your method should be

CreateFile(id, name, description, SupportedPermissions.basic);

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,
              /* --> */  SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions // <---
    };

    return file.Id;
}

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <---
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = SupportedPermissions.basic // <---
    };

    return file.Id;
}
