String to variable

I have a variable t开发者_JAVA技巧est..

String test = TextBox1.Text;

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

---

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

---

Edit:

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

---

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.

---

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;
    }
