-> In C# 8, the [null-forgiving operator](null-forgiving.md) terminates the list of preceding null-conditional operations. For example, the expression `x?.y!.z` is parsed as `(x?.y)!.z`. Due to this interpretation, `z` is evaluated even if `x` is `null`, which may result in a <xref:System.NullReferenceException>.

 ### Thread-safe delegate invocation
 
 Use the `?.` operator to check if a delegate is non-null and invoke it in a thread-safe way (for example, when you [raise an event](../../../standard/events/how-to-raise-and-consume-events.md)), as the following code shows:

 The null-forgiving operator has no effect at run time. It only affects the compiler's static flow analysis by changing the null state of the expression. At run time, expression `x!` evaluates to the result of the underlying expression `x`.
