What's the equivalent of VB's Asc() and Chr() functions in C#?

VB has a couple of native functions for converting a char to an ASCII value and vice versa - Asc() and Chr().

Now I need to get the equivalent functionality in C#. What's the best way?

From stackoverflow

• For Asc() you can cast the char to an int like this:

  int i = (int)your_char;
  

  and for Chr() you can cast back to a char from an int like this:

  char c = (char)your_int;
  

  Here is a small program that demonstrates the entire thing:

  using System;
  
  class Program
  {
      static void Main()
      {
       char c = 'A';
       int i = 65;
  
          // both print "True"
       Console.WriteLine(i == (int)c);
       Console.WriteLine(c == (char)i);
      }
  }
  

• You can use the Convert class. From char to ascii:

  int asciiValue = Convert.ToInt32('a');
  

  And then back from ascii value to char:

  char c = Convert.ToChar(asciiValue);
  

  Andrew Hare : Whoa - I accidentally edited your answer instead of mine!! Sorry about that!

  Razzie : Heh, it's ok. As long as it's for the better ;-)

• For Chr() you can use:

  char chr = (char)you_char_value;
  

• Try this...

  sum += (int) str[i];
  

• Given char c and int i, and functions fi(int) and fc(char):

  From char to int (analog of VB Asc()): explicitly cast the char as an int: i = (int) c;

  or mplicitly cast (promote): fi(c), i+= c;

  From int to char (analog of VB Chr()):

  explicitly cast the int as an char: c = (char) i, fc( (char) i);

  An implicit cast is disallowed, as an int is wider (has a greater range of values) than a char

• You could always add a reference to Microsoft.VisualBasic and then use the exact same methods: Strings.Chr and Strings.Asc.

  That's the easiest way to get the exact same functionality.

  Shaul : Except that Strings class doesn't exist inside .NET 2008... :(

  Samuel : If you add a reference, it will exist.

• How would I do this WITHOUT using Chr() or Asc()?

  I want to use true vb.net functions only.

  Dim n As Int16

  Dim s As String = "A"

  n= Asc(s) ' n will now equal 65

  s = Chr(n) ' s will now equal "A"
