How to convert string into int in unity C#

 We can use int.Parse() or int.TryParse() method for converting a string into int in unity as we use regular C# language. here is an example of  int.Parse() :

Code :

string input = "123";

int result = int.Parse(input);

Debug.Log(result); // Output: 123

Example of int.TryParse()  given below: 

Code :

string input = "123";

int result;

bool success = int.TryParse(input, out result);

if (success)

{

    Debug.Log(result); // Output: 123

}

else

{

    Debug.Log("Invalid input");

}

int.TryParse(input, out result)  is a safer method because we can check if a given string is actually a int or not so we can minimize some exception errors.

Additionally, We can also use Convert.ToInt32() method to convert a string into into, example of Convert.ToInt32() is given below:

Code :

string input = "123";

int result = Convert.ToInt32(input);

Debug.Log(result); // Output: 123

an exception will we throw by this method if string is not a integer. you can use any of the above method according to your requirement.
