C# Linq - If input is not equal to any of the string[]

Question

I have an error code here, because I can't check if string is equal to string[].

public void SetCh1Probe(string input)
{
    string[] option= {"1:1", "1:10", "1:100"}

    //I wanna check if input is equal to any of the string array
    if (input != option.Any(x => x == option))
    {
        MessageBox.Show("Invalid Input");
    }

    else
    {
        //Proceed with other stuffs
    }
}

I will have tons of methods like this, each with different string[] options. I really want to have a neat template that I can use for the rest of the methods. Can anybody help?

I believe setting.Any should be option.Any If I understand your question correctly — Mohit S

Change your condition from

if (input != option.Any(x => x == option))

To

if (!option.Any(x => x == input))

Or another alternative

if (option.All(x => x != input))

Please try with the below code snippet.

    public void SetCh1Probe(string input)
    {
        string[] setting = { "1:1", "1:10", "1:100" };

        //I wanna check if input is equal to any of the string array
        if (!setting.Contains(input))
        {
            //MessageBox.Show("Invalid Input");
        }

        else
        {
            //Proceed with other stuffs
        }
    }
