What are types of irony in "Macbeth"?

Shakespeare's play "Macbeth" contains situational irony and dramatic irony. The premise of the play itself is ironic, as Macbeth aims to become king to better himself, but his guilt from usurping the throne and committing murder ends up committing him to a downward spiral.

The irony in "Macbeth" is both situational and tragically dramatic. Macbeth is told by the witches that he will become king. He assumes that becoming king will gain him respect and a happy life, but the crimes that he commits to gain the throne mean that his fellow thanes eventually discover his crimes and kill him.
