Contract.Requires Method (Boolean)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Specifies a precondition contract for the enclosing method or property.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- condition
- Type: System.Boolean
The conditional expression to test.
This method call must be at the beginning of a method or property, before any other code.
This contract is exposed to clients; therefore, it must only reference members that are at least as visible as the enclosing method.
Use this method instead of the Contract.Requires<TException>(Boolean) method when backward compatibility does not force you to throw a particular exception.
