How can I convert the TextMeshPro text to an int?

Question

I'm having trouble trying to convert from string to int in unity. It keeps giving me FormatExceptions.

In my editor i have dragged a reference to the text object in my scene to the script itself. Its type is TMP_Text. Lets call textObject. When calling the ParseString Method i pass in the textObject.text property since its the string i'm looking for. I have confirmed this with a Debug.Log (which works fine btw)

What i've tried so far:

 private static int ParseString(string dayText)
     {
         int num = 0;
         num = int.Parse(dayText);
         return num;
     }

This throws a FormatException

 private static int ParseString(string dayText)
     {    
         int num = 0;
         if int.TryParse(dayText, out num);
             return num;
 
         throw new System.ArgumentException("Argument must be a number");
     }

Here the TryParse returns false and the ArgumentException is thrown.

 private static int ParseString(string dayText)
     {
         dayText = string.Format("{0}", dayText);
 
         int num = 0;
         num = System.Convert.ToInt32(dayText);
         return num;
 
         throw new System.ArgumentException("Argument must be a number!");
     }

Here I get another FormatException.

 private static int ParseString(string dayText)
 {
     dayText = string.Format("{0}", dayText);

     int num = 0;
     if (int.TryParse(dayText, out num);
         return num;

     throw new System.ArgumentException("Argument must be a number!");
 }

I tried using the formatting method which didn't work. Still throws the ArgumentException.

 private static int ParseString(string text)
     {
         string temp = "1";
         temp = temp + text;
         int num = 0;
         if (int.TryParse(dayText, out num);
             return num;
 
         throw new System.ArgumentException("Argument must be a number!");
     }

I tried some concatination. Still returns false and throws the ArgumentException.

And for the record i tried all the above methods with each of the converting Methods. the other two throws a FormatException instead of the ArgumenteException i wrote.

Additionally i made a test script and tried some of the same conversion using that TMP_Text reference again, but a completely new one, seperate from anything that was already in the scene. Still no conversion on the object, but works fine when i define my own strings somewhere in the class or even change them at runtime with a [SerializedField] private string text;

I tried passing in my own string defined in the method where i use ParseString() and it works as expected. I did the same, defining a field and a property in the class.

I'm starting to believe there is no way around this and i have to find an alternative. It might just be a problem

This seems to be a very annoying issue. The solution to my problem ended up being to use the TMP_InputField directly rather than TMP_Text. For some reason the conversions work then. Its strange because all that does is get get the text stored in its child TMP_Text object… Regardless it did the job for me, maybe it will for you.

Hi, instead of dayText use dayText.GetParsedText()

l mean:

int.TryParse(dayText.GetParsedText(), out num)

I've tried this in 2021.3.1f1 and int.Parse functions were still not able to figure out TMP text. Here is my code:

 public void OnChangeWidth(TMP_Text text)
 {
         int value = 0;
         Debug.Log(text.GetParsedText());
         if (text.GetParsedText().Equals("1"))
             Debug.Log("Equals 1!");
         if(int.TryParse(text.GetParsedText(), out value))
         {
             Debug.Log("Parsed value: " + value);
         }
 }

And here is the output I get:
