Lazy<T> Constructor (Boolean)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Initializes a new instance of the Lazy<T> class. When lazy initialization occurs, the default constructor of the target type and the specified initialization mode are used.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- isThreadSafe
- Type: System.Boolean
true to make this instance usable concurrently by multiple threads; false to make the instance usable by only one thread at a time.
The thread safety mode of a Lazy<T> instance that is initialized with this constructor is LazyThreadSafetyMode.ExecutionAndPublication if isThreadSafe is true; otherwise, the mode is LazyThreadSafetyMode.None. The thread safety mode describes the behavior when multiple threads try to initialize the Lazy<T> instance. To specify the LazyThreadSafetyMode.PublicationOnly mode, use the Lazy<T>(Func<T>, LazyThreadSafetyMode) or Lazy<T>(LazyThreadSafetyMode) constructor.
A Lazy<T> instance that is created with this constructor does not cache exceptions. For more information, see the System.Threading.LazyThreadSafetyMode enumeration.
