var permissionresult = UpdatePermission(service, "fileid", "permissionid", "owner");


public static Permission UpdatePermission(DriveService service, String fileId,
    String permissionId, String newRole)
{
    try
    {
        // First retrieve the permission from the API.
        Permission permission = service.Permissions.Get(fileId, permissionId).Execute();
        permission.Role = newRole;

        return service.Permissions.Update(permission, fileId, permissionId).Execute();
    }
    catch (Exception e)
    {
        Console.WriteLine("An error occurred: " + e.Message);

You need to init a new Permission instance or use the existing to modify the Role, Type and Value fields:

Permission p = new Permission();
p.Role = "owner";
p.Type = "user";
p.Value = "jbd@google.com";
service.Permissions.Update(p, fileId, permissionId);

You only change owner the files or folders you own.

Permission permission = new Permission
            {
                Role = "owner",
                Type = "user",
                EmailAddress = "abcnewideal2020@gmail.com"
            };

            //Call the TransferOwnership property
            var updatePermission = service.Permissions.Update(permission, fileId, permissionId);
            updatePermission.TransferOwnership = true;
            return updatePermission.Execute();

Hope this help!

I think this is what you wanted:

var permissionresult = UpdatePermission(service, "fileid", "permissionid", "owner");


public static Permission UpdatePermission(DriveService service, String fileId,
    String permissionId, String newRole)
{
    try
    {
        // First retrieve the permission from the API.
        Permission permission = service.Permissions.Get(fileId, permissionId).Execute();
        permission.Role = newRole;

        //Call the TransferOwnership property
        var updatePermission = service.Permissions.Update(permission, fileId, permissionId);
        updatePermission.TransferOwnership = true;
        return updatePermission.Execute();
    }
    catch (Exception e)
    {
        Console.WriteLine("An error occurred: " + e.Message);
    }
    return null;
}
