File exist, path is null but isn't C#

Hi, I'm trying to load file as text. This is working in editor but not in build:

 BinaryFormatter bf = new BinaryFormatter();
 FileStream file = File.Open("Assets/Door/Resources/Saves" + "/myGame_" + saveLevelInt + "_" + saveSlotInt + ".txt", FileMode.Open);
 playerData data = (playerData)bf.Deserialize(file);
 file.Close ();
 // do rest

Because it's not working in build I tried to use Resources.Load but it looks like I miss something, here is code:

 BinaryFormatter bf = new BinaryFormatter();
 TextAsset hila = (TextAsset)Resources.Load("Saves/myGame_" + saveLevelInt + "_" + saveSlotInt, typeof(TextAsset));
 if(hila == null)
 print("there is no file");// never prints if not modify path and file exist in folders

 FileStream file = File.Open(hila.ToString(), FileMode.Open); // in this line i get error**
 playerData data = (playerData)bf.Deserialize(file);
 file.Close ();
 //do rest

**that error:

ArgumentException: Path is empty.

Problem is I cannot make saves in runtime, they are always from files made before game is builded. It's specyfic case :D

Hello,

Not sure that Hila.ToString() will actually work, maybe try hila.Text (doc)

ANd use if(String.IsNullOrEmpty(hila.Text)) print("...");

Hi @Nerevar, now it prints always :( Trying now to understand links which @saud_ahmed020 gave. Edit: Modified line to:

 TextAsset hila = (TextAsset)Resources.Load("Saves/myGame_" + saveLevelInt + "_" + saveSlotInt + ".txt", typeof(TextAsset));
 if(string.IsNullOrEmpty(hila.text))
 print("something wrong"); // now never prints if file exist in folder but get bug:
 //NullReferenceException: Object reference not set to an instance of an object// in line above
 // "if(string.IsNullOrEmpty(hila.text))"

I made hila as public TextAsset, then trying to File.Open... but then path is null as on first post :(
