Question

This C# code is simple:

The scenario of this code:

When the word is matched it results unexpected output:

The word is found
The word is not found
The value of found is: True

When the word is not matched it results the expected output:

The word is not found
The value of found is: False

    static void Main()
    {
        string[] words = { "casino", "other word" };

        Boolean found = false;
            foreach (string word in words)
            {
                if (word == "casino")
                {
                    found = true;
                    goto Found;
                }
            }

        if(!found)
        {
            goto NotFound;
        }

    Found: { Console.WriteLine("The word is found"); }
    NotFound: { Console.WriteLine("The word is not found"); }

        Console.WriteLine("The value of found is: {0}", found);

        Console.Read();
    }

The goto statement just moves the execution to that point. So in you case the Found is being executed then the next line, NotFound, is being executed.

To fix this using goto you would have to have a 3rd goto which is something like Continue.

static void Main()
{
    string[] words = { "casino", "other word" };

    Boolean found = false;

    foreach (string word in words)
    {
        if (word == "casino")
        {
            found = true;
            goto Found;
        }
    }

    if(!found)
    {
        goto NotFound;
    }

    Found: { Console.WriteLine("The word is found"); goto Continue; }
    NotFound: { Console.WriteLine("The word is not found"); }

    Continue:
    Console.WriteLine("The value of found is: {0}", found);

    Console.Read();
}

I would much prefer something like this however:

static void Main()
{
    string[] words = { "casino", "other word" };

    Boolean found = false;

    foreach (string word in words)
    {
        if (word == "casino")
        {
            found = true;
            break;
        }
    }

    if(!found)
    {
        Console.WriteLine("The word is not found");
    }
    else
    {
        Console.WriteLine("The word is found");
    }

    Console.WriteLine("The value of found is: {0}", found);

    Console.Read();
}

Or even better!

static void Main()
{
    string[] words = { "casino", "other word" };

    if (words.Contains("casino"))
    {
        Console.WriteLine("The word is found");
    }
    else
    {
        Console.WriteLine("The word is not found");
    }

    Console.Read();
}
