how to get string in stringcontains c# in unity?

Question

can i get string from string contains? when i type "asdsahello1" how to get string on list only "hello1" in contains string.

public class FindContainsText : MonoBehaviour
{
private string[] test = { "hello1", "hello2" };
public Inputfield inputText;

void Update()
{
  foreach (string x in test)
    {
       if(inputText.Contains(x))
        {
        string getString;
        getString=//inputText.Contains(x) how?
        }
    }
}
}

You can use for( int i=0 ; i<array.Length ) loop here. Given if(true) break;, i will be index you're looking for — Andrew Łukasik

It should probably be inputText.Contains(x) rather than inputText.Contains.x. — joll05

Try this code snippet:

public class FindContainsText : MonoBehaviour
{
    private string[] test = { "hello1", "hello2" };
    public InputField inputText;

    public void Update()
    {
        int matchIndex = -1;
        for (int i = 0; i < test.Length; i++)
        {
            if (inputText.text.Contains(test[i]))
            {
                matchIndex = i;
                break;
            }
        }

        if (matchIndex != -1)
        {
            Debug.Log($"Input field contains {test[matchIndex]} (element number {matchIndex})");
        }
        else
        {
            Debug.Log("No match!");
        }
    }
}

Also consider using onValueChanged event instead of Update. It gets called each time the Inputfield is updated.

getString=x;

Varible x contains value that you are testing.

x = hello1 and hello2

Ye, your string can conteins some your test strings e.g. "asdsahello1asdasdsahello2". And you can get all matches.
