How to get ASCII value of string in C#

How to get ASCII value of string in C#

In C#, you can use the Encoding.ASCII.GetBytes method to get the ASCII value of a string. Here's an example:

 string myString = "Hello World!"; byte[] asciiBytes = Encoding.ASCII.GetBytes(myString); foreach (byte b in asciiBytes) { Console.WriteLine(b); }

This code will output the ASCII values of each character in the string:

 72 101 108 108 111 32 87 111 114 108 100 33

Note that the ASCII value of a character is simply its corresponding numerical value in the ASCII table.

Examples

  1. "C# get ASCII values of characters in a string"

    • Description: Obtain the ASCII values of characters in a string using LINQ.
    • Code:
      string inputString = "Hello, World!"; var asciiValues = inputString.Select(c => (int)c); // Now 'asciiValues' contains the ASCII values of each character in the string

  2. "C# convert string to ASCII values array"

    • Description: Convert a string to an array of ASCII values using a loop.
    • Code:
      string inputString = "Hello, World!"; int[] asciiValues = new int[inputString.Length]; for (int i = 0; i < inputString.Length; i++) { asciiValues[i] = (int)inputString[i]; } // Now 'asciiValues' contains the ASCII values of each character in the string

  3. "C# get ASCII value of first character in string"

    • Description: Retrieve the ASCII value of the first character in a string.
    • Code:
      string inputString = "Hello, World!"; int firstCharAsciiValue = (int)inputString[0]; // 'firstCharAsciiValue' now holds the ASCII value of the first character

  4. "C# ASCII encoding for string"

    • Description: Use ASCII encoding to get byte array representation of a string.
    • Code:
      string inputString = "Hello, World!"; byte[] asciiBytes = Encoding.ASCII.GetBytes(inputString); // Now 'asciiBytes' contains the ASCII values in byte form for each character

  5. "C# LINQ ASCII values with index"

    • Description: Use LINQ to obtain ASCII values along with their index in a string.
    • Code:
      string inputString = "Hello, World!"; var asciiValuesWithIndex = inputString.Select((c, index) => new { Character = c, Index = index, ASCIIValue = (int)c }); // Now 'asciiValuesWithIndex' contains objects with character, index, and ASCII value information

  6. "C# get ASCII values excluding non-alphanumeric characters"

    • Description: Filter out non-alphanumeric characters and get their ASCII values.
    • Code:
      string inputString = "Hello, World!"; var alphanumericAsciiValues = inputString.Where(char.IsLetterOrDigit).Select(c => (int)c); // 'alphanumericAsciiValues' now contains ASCII values of alphanumeric characters

  7. "C# get ASCII values with ASCII encoding class"

    • Description: Utilize the ASCIIEncoding class to convert a string to ASCII values.
    • Code:
      string inputString = "Hello, World!"; var asciiBytes = new ASCIIEncoding().GetBytes(inputString); int[] asciiValues = asciiBytes.Select(b => (int)b).ToArray(); // Now 'asciiValues' contains the ASCII values of each character in the string

  8. "C# ASCII values as hexadecimal"

    • Description: Convert ASCII values to hexadecimal representation in C#.
    • Code:
      string inputString = "Hello, World!"; var hexAsciiValues = inputString.Select(c => ((int)c).ToString("X2")); // 'hexAsciiValues' now contains hexadecimal representations of ASCII values

  9. "C# ASCII values with StringBuilder"

    • Description: Build a StringBuilder with ASCII values of characters in a string.
    • Code:
      string inputString = "Hello, World!"; var stringBuilder = new StringBuilder(); foreach (char c in inputString) { stringBuilder.Append((int)c).Append(" "); } string result = stringBuilder.ToString().Trim(); // 'result' now contains the ASCII values separated by space

  10. "C# ASCII values with LINQ and distinct"

    • Description: Use LINQ to get distinct ASCII values from a string.
    • Code:
      string inputString = "Hello, World!"; var distinctAsciiValues = inputString.Select(c => (int)c).Distinct(); // 'distinctAsciiValues' now contains distinct ASCII values from the string
