public class ExampleClass { public int ExampleMethod(int n) { CodeContract.Requires(n > 0, "n must be greater than 0"); CodeContract.Ensures( CodeContract.Result () >= 0, "Return value must be positive"); //... } public IEnumerable Contents { get; set; } [ContractInvariantMethod] protected void ObjectInvariant() { CodeContract.Invariant( CodeContract.ForAll(Contents, s => s != null)); //... } Contracts come at the beginning of methods. Precondition stating that the input parameter to the method must be greater than 0 for the method to function properly. Postcondition guaranteeing that the result of the method will be positive. Callers can count on this. Developers can provide a string to be displayed when the contract is violated. All object invariants are contained in a single method, which may contain many calls to CodeContract.ObjectInvariant and no other calls. Guarantees that all elements in the IEnumerable are not null.
