String to variable

Question

I have a variable test..

String test = TextBox1.Text;

I want to know if the user enters into this variable 04151.

I think you might need to lookup some beginner C# tutorials... — Yngve B-Nilsen

There's nothing wrong with beginner questions. Especially since it is a library question, essentially. — John Gietzen

if (test == "04151")
{
    MessageBox.Show("Yep!");
}

Edit:

if (test.Contains("04151"))
{
    MessageBox.Show("Yep!");
}

if the user enters "Ex H 4 04151" how do I check?

@sowulo - test.Contains("04151")

if( test == "04151" )
{
   //04151 was entered
}

?

If this is some type of checking a password, I would strongly urge you to do it in a safer way than checking towards a hard coded string inside your app. There are many issues with that approach. For one, you will have to recompile your program to alter your password.

Based on his comment above, I don't think that it is a password.

@John - Nope, but I was afraid it could be when I read his initial question ;)

You could put the other answers in the TextChanged event, to check it every time the user changes the text

    public bool Matches(string test)
    {
        return String.Compare(test, "04151", true) == 0;
    }

you couldn't manage to make a single string comparison more difficult for a beginner? :)
