How do I find the size of an enum? The Enum. values() returns an array of all the enum constants. You can use the length variable of this array to get the number of enum
How do I find the size of an enum?
The Enum. values() returns an array of all the enum constants. You can use the length variable of this array to get the number of enum constants. length is not a method of an array, it is a property field, so you’d use it without parentheses.
How big is an enum in C#?
On an 8-bit processor, enums can be 16-bits wide. On a 32-bit processor they can be 32-bits wide or more or less. The GCC C compiler will allocate enough memory for an enum to hold any of the values that you have declared. So, if your code only uses values below 256, your enum should be 8 bits wide.
How many bytes is an enum C#?
|Range of Element Values||Enum Options|
|0 .. 65535||2 bytes unsigned||4 bytes signed|
|-32768 .. 32767||2 bytes signed||4 bytes signed|
|0 .. 2147483647||4 bytes unsigned||4 bytes signed|
What is the size of this enum in bytes?
This compiler is 64-bit. Underlying type is ‘unsigned int’. Size = 4 bytes. If you create a variable of the enum type, it must have a minimum size of 1.
When should I use enum in C#?
In C#, an enum (or enumeration type) is used to assign constant names to a group of numeric integer values. It makes constant values more readable, for example, WeekDays. Monday is more readable then number 0 when referring to the day in a week.
What is default value of enum C#?
The default value for an enum is zero.
What is typedef enum in C?
A typedef is a mechanism for declaring an alternative name for a type. An enumerated type is an integer type with an associated set of symbolic constants representing the valid values of that type.
What is the size of enum class?
The size is four bytes because the enum is stored as an int . With only 12 values, you really only need 4 bits, but 32 bit machines process 32 bit quantities more efficiently than smaller quantities. Without enums, you might be tempted to use raw integers to represent the months.
How is enum stored in memory?
As enum types are handled as integral types, they are stored in the stack and registers as their respective data types: a standard enum is usually implemented as an int32; this means that the compiler will handle your enum as a synonym of int32 (for the sake of simplicity, I left out several details).
