Which modifiers are allowed in enum?
So the access modifiers rules for enums are the same as those used for a standard classes. For the exam, keep in mind that you CAN define a enum as protected, private or even static only if such enum is a member of another class, otherwise, the only modifiers allowed are public or none (which behaves as default).
Can you specify an access modifier for an enumeration?
Enumeration members are always public , and no access modifiers can be applied.
Can enum have int values?
The enum can be of any numeric data type such as byte, sbyte, short, ushort, int, uint, long, or ulong. However, an enum cannot be a string type.
Is enum an int C#?
By default, the type for enum elements is int. We can set different type by adding a colon like an example below. The different types which can be set are sbyte, byte, short, ushort, uint, ulong, and long.
Which modifier is not allowed in enum?
Why Enum constructor can’t have protected or public access modifier.
Which access modifiers can be used on the constructor of an enum class?
The access modifier of constructor for an enum type must be either private or package-private(no modifier).
What are the access modifiers allowed in C#?
C# provides four types of access modifiers: private, public, protected, internal, and two combinations: protected-internal and private-protected.
How do I assign an enum to an integer?
You can use: int i = Convert. ToInt32(e); int i = (int)(object)e; int i = (int)Enum. Parse(e.
How do you use integers in enum?
- To get the enum for a given integer, we simply have to call the valueOf method, like below.
- On the other hand, to get the integer value from an enum, one can do as follows, by using the getValue method.
- The getValue method simply returns the internal value of the enum that we store within the value variable.
Can I assign int to enum?
You can explicitly type cast an int to a particular enum type, as shown below.
Are enums ints?
I recently explained that although both C and C++ provide void * as the generic data pointer type, each language treats the type a little differently. For any object type T , both C and C++ let you implicitly convert an object of type T * to void * .
How do you define an enum?
An enum type is a special data type that enables for a variable to be a set of predefined constants. The variable must be equal to one of the values that have been predefined for it. Common examples include compass directions (values of NORTH, SOUTH, EAST, and WEST) and the days of the week.

What are access specifiers and access modifiers in C#?

Can you cast int to enum C#?
How do I change the value of an enum?
Enum constants are implicitly static and final and you can not change their value once created. Enum in Java provides type-safety and can be used inside switch statements like int variables.
What is enum in C# with example?
An enum is a special “class” that represents a group of constants (unchangeable/read-only variables).
What is the correct syntax of enum?
