answer t or f if false explain why, c#/.net based questions

1. T/F A delegate allows you to define a method, and later, assign a method that will run when the delegate is called

2. T/F You can only assign a single method to a delegate.

3. T/F Events can be raised by objects even if there are no listeners registered to handle the event.

4. T/F EventArgs can be used to pass additional information to an event handler

5. T/F When adding an indexer to a class, you must have both get and set options

6. T/F An extension method allows you to add additional methods to a class without having to modify the actual class

7. T/F A lambda expression is an anonymous method

8. T/F A lambda expression can be used to make a computed value appear like a Property.

9. T/F Query expression syntax can be used on any ICollection

10. T/F Query clauses can alternatively be called by using methods

1. Using threads allows you to __________________________________________

2. T/F When multiple threads are accessing the same object, you should use blocks to prevent them from accessing it

at the same time and overwriting changes the other made.

3. T/F ThreadPool is useful to ensuring you dont create too many threads that compete for processor time and end

up slowing each other down

4. T/F The await keyword allows C# to continue past code that is calling an async method and will complete the code

after await once the async method completes.

5. T/F Task is used by async tasks to define a specific type of result that will be returned

6. T/F The yield keyword allows a method to return a value and wait to continue running until it is called again

7. T/F - The nameof() operator is used to get the string value a variable references

8. T/F const variables are automatically set as static

9. T/F using the dynamic type allows C# to use typeless variables, which could cause Runtime errors if we attempt to

use them in ways that cant happen at runtime

10. T/F using the unsafe keyword allows for direct manipulation of memory and pointers, like using C++ in our C# code
