Convert.ToChar Method (String)

Updated: May 2009

Converts the first character of a specified string to a Unicode character.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static char ToChar(
	string value
)

Parameters

value
Type: System.String

A string of length 1.

Return Value

Type: System.Char
A Unicode character that is equivalent to the first and only character in value.

ExceptionCondition
ArgumentNullException

value is null.

FormatException

The length of value is not 1.

value must be a string that contains a single character.

If you prefer not to handle an exception if the conversion fails, you can call the Char.TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.

The following example converts each element in a string array to a Char value.

string nullString = null;
string[] strings = { "A", "This",  '\u0007'.ToString(), nullString };
char result;
foreach (string strng in strings)
{
   try {
      result = Convert.ToChar(strng);
      Console.WriteLine("'{0}' converts to '{1}'.", strng, result);
   }   
   catch (FormatException)
   {
      Console.WriteLine("'{0}' is not in the correct format for conversion to a Char.",
                        strng);
   }
   catch (ArgumentNullException) {
      Console.WriteLine("A null string cannot be converted to a Char.");
   }   
}
// The example displays the following output: 
//       'A' converts to 'A'. 
//       'This' is not in the correct format for conversion to a Char. 
//       '       ' converts to ' '. 
//       A null string cannot be converted to a Char.
