Example

[Visual Basic, C#, C++] The following code sample illustrates the conversion of a Char to a String, using ToString.

[Visual Basic] 
Public Sub ConvertStringChar(ByVal stringVal As String)
    Dim charVal As Char = "a"c

    ' A string must be one character long to convert to char.
    Try
        charVal = System.Convert.ToChar(stringVal)
        System.Console.WriteLine("{0} as a char is {1}", _
                                  stringVal, charVal)
    Catch exception As System.FormatException
        System.Console.WriteLine( _
         "The string is longer than one character.")
    Catch exception As System.ArgumentNullException
        System.Console.WriteLine("The string is null.")
    End Try

    ' A char to string conversion will always succeed.
    stringVal = System.Convert.ToString(charVal)
    System.Console.WriteLine("The character as a string is {0}", _
                              stringVal)
End Sub

[C#] 
public void ConvertStringChar(string stringVal) {
    char charVal = 'a';

    // A string must be one character long to convert to char.
    try {
        charVal = System.Convert.ToChar(stringVal);
        System.Console.WriteLine("{0} as a char is {1}",
            stringVal, charVal);
    }
    catch (System.FormatException) {
        System.Console.WriteLine(
            "The string is longer than one character.");
    }
    catch (System.ArgumentNullException) {
        System.Console.WriteLine("The string is null.");
    }

    // A char to string conversion will always succeed.
    stringVal = System.Convert.ToString(charVal);
    System.Console.WriteLine("The character as a string is {0}",
            stringVal);
}

[C++] 

   void ConvertStringChar(String* stringVal)
   {
      Char charVal = 'a';

      // A String* must be one character long to convert to char.
      try {
         charVal = System::Convert::ToChar(stringVal);
         System::Console::WriteLine(S" {0} as a char is {1}",
            stringVal, __box(charVal));
      } catch (System::FormatException*) {
         System::Console::WriteLine(S"The String* is longer than one character.");
      } catch (System::ArgumentNullException*) {
         System::Console::WriteLine(S"The String* is 0.");
      }

      // A char to String* conversion will always succeed.
      stringVal = System::Convert::ToString(charVal);
      System::Console::WriteLine(S"The character as a String* is {0}",
         stringVal);
   }
