Answer: Option E
Solution (By Examveda Team)
The question asks which method of the String class in C# is used to extract all characters from a string.The correct method is ToCharArray(), which converts the entire string into an array of characters.
Syntax:
char[] ToCharArray()This method returns a character array containing all the characters of the string in the same sequence.
Example:
string myString = "Hello";char[] chars = myString.ToCharArray();After execution,
chars will contain: ['H', 'e', 'l', 'l', 'o'].Option A: CHARAT() – Invalid in C#. It belongs to Java and has incorrect casing.
Option B: Remove() – Used to delete a portion of a string, not to extract characters.
Option C: charAt() – Also a Java method, not part of C#.
Option D: Replace() – Used to replace characters or substrings, not to extract them.
Therefore, the correct and updated answer is Option E: ToCharArray().
