read text file parse problem

Question

Hi everyone,

I'm asking because after several day of research I m still blocked.

I have a text file with this format:

  C     -0.662479     3.460245     1.908363
  C     0.419934     3.067604     1.127385
  C     0.374974     1.869134     0.409111
  C    -0.769773     1.068668     0.479418

And I want to instantiate a Gameobject with those coordinates, for this I use this code:

 public GameObject atomes;
     public class Atome : MonoBehaviour
     {
 
         public string atome_symbol;
         public string atome_x;
         public string atome_y;
         public string atome_z;
     }
 
     public void Read()
     {
         int i = 1;
         string atome_symbole = "";
         float atome_x = 0.0f;
         float atome_y = 0.0f;
         float atome_z = 0.0f;
 
         string[] separatingChars = { " " };
 
         string[] lines = System.IO.File.ReadAllLines(@"C:\Users\Pauze\Desktop\geometry.txt");
 
         foreach (string linea in lines)
         {
             string line= linea.Trim();
             line = line.Replace("      ", " ");
             line = line.Replace("     ", " ");
             line = line.Replace("    ", " ");
             line = line.Replace("   ", " ");
             line = line.Replace("     ", " ");
             string[] entries = line.Split(separatingChars, System.StringSplitOptions.None);
             
             atome_symbole = entries[0];
             atome_x = float.Parse(entries[1]);
             atome_y = float.Parse(entries[2],System.Globalization.NumberStyles.AllowDecimalPoint);
             atome_z = float.Parse(entries[3]);
 
 
 
             GameObject newatome =  Instantiate(atomes,new Vector3(atome_x,atome_y,atome_z), Quaternion.identity );
             newatome.transform.name = $"{atome_symbole}_{i}";
             GameObject.Find($"{atome_symbole}_{i}").GetComponent<atome>().atome_sym = atome_symbole;
 
             Debug.Log($"{line} + {atome_x} + {atome_y} + {atome_z}");
             i++;
 
                    }
     }
     }

My problem is the split is not working properly. In the consol I have this:

 C 0.419934 3.067604 1.127385 + 0.419934 + 0 + 0
 UnityEngine.Debug:Log(Object)
 dreader:Read() (at Assets/scripts/dreader.cs:61)
 UnityEngine.EventSystems.EventSystem:Update()

I try tu use the Try.parse also, didn't work.

does anyone have an idea? I was thinking about changing the format of the file with code before to read it, but if what I'm doing here is not working, I don't think it will work if I try to do it before.

Thanks a lot for any suggest!

     for( int lineIndex = 0 ; lineIndex < lines.Length ; ++lineIndex )
     {
         string[] entries = lines[lineIndex].Split(separatingChars, System.StringSplitOptions.RemoveEmptyEntries);

         string atome_symbole = entries[0];
         float atome_x = float.Parse(entries[1]);
         float atome_y = float.Parse(entries[2]);
         float atome_z = float.Parse(entries[3]);

         GameObject newatome =  Instantiate(atomes,new Vector3(atome_x,atome_y,atome_z), Quaternion.identity );
         newatome.transform.name = $"{atome_symbole}_{i}";
         GameObject.Find($"{atome_symbole}_{lineIndex}").GetComponent<atome>().atome_sym = atome_symbole;

         Debug.Log($"{lines[lineIndex]} + {atome_x} + {atome_y} + {atome_z}");
 
     }

Thanks a lot, I still don't really understand why this is working and not my code ...

Using the System.StringSplitOptions.RemoveEmptyEntries instead of the multiple calls to string.Replace solved many problems.
