💡 Hint

Common Mistakes

Using parentheses instead of curly braces.

Using square brackets or angle brackets.

Enums in C# are declared with curly braces { } to list their values.

💡 Hint

Common Mistakes

Using a string "100" instead of number 100.

Using variable names instead of values.

Constants are assigned a fixed value directly, here 100 as an integer.

💡 Hint

Common Mistakes

Using only the member name without enum type.

Trying to access enum members like an array.

Enum values must be accessed with the enum type name, like Color.Green.

4fill in blank

hard

C Sharp (C#)

public const [1] Status = [2];

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using unquoted text for string constants.

Using wrong type like int for string values.

Constants need a type and a value; string type and quoted string value are required here.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping enum Color to string names, including only Red and Blue.

C Sharp (C#)

var colorNames = new Dictionary<Color, [1]> { {Color.Red, [2], {Color.Blue, [3] };

Drag options to blanks, or click blank then click option'

Astring

B"Red"

C"Blue"

Dint

💡 Hint

Common Mistakes

Using int instead of string as dictionary value type.

Not quoting string values.

The dictionary maps Color enum keys to string values representing their names.
