Given a char, the task is to convert this ASCII character into a Byte in C#.

Examples:

Input: chr = 'a'
Output: 97
  
Input: chr = 'H'
Output: 72

Method 1: Naive Approach

Step 1: Get the character.

Step 2: Convert the character using the Byte struct

byte b = (byte) chr;

Step 3: Return or perform the operation on the byte 

Below is the implementation of the above approach:

Output:

Byte of char 'G' : 71

Method 2: Using ToByte() Method: This method is a Convert class method. It is used to converts other base data types to a byte data type.

Syntax:

byte byt = Convert.ToByte(char); 

Below is the implementation of the above approach:

Output:

Byte of char 'G' : 71

Method 3: Using GetBytes()[0] Method: The Encoding.ASCII.GetBytes() method is used to accepts a string as a parameter and get the byte array. Thus GetBytes()[0] is used to get the byte after converting the character into string.

Syntax:

byte byt = Encoding.ASCII.GetBytes(string str)[0]; 

Step 1: Get the character.

Step 2: Convert the character into string using ToString() method.

Step 3: Convert the string into byte using the GetBytes()[0] Method and store the converted string to the byte.

Step 4: Return or perform the operation on the byte.

Below is the implementation of the above approach:

Output:

Byte of char 'G' : 71
