The Unicode character to convert.

Return Value

Type: System.Int32
A 32-bit signed integer that is equivalent to value.

The following example converts each element in an array of Char values to an integer.

char[] chars = { 'a', 'z', '\u0007', '\u03FF',
                 '\u7FFF', '\uFFFE' };
int result;

foreach (char ch in chars)
{
   try {
      result = Convert.ToInt32(ch);
      Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.",
                        ch.GetType().Name, ch,
                        result.GetType().Name, result);
   }
   catch (OverflowException) {
      Console.WriteLine("Unable to convert u+{0} to an Int32.",
                        ((int)ch).ToString("X4"));
   }
}   
// The example displays the following output: 
//       Converted the Char value 'a' to the Int32 value 97. 
//       Converted the Char value 'z' to the Int32 value 122. 
//       Converted the Char value '' to the Int32 value 7. 
//       Converted the Char value '?' to the Int32 value 1023. 
//       Converted the Char value '?' to the Int32 value 32767. 
//       Converted the Char value '?' to the Int32 value 65534.
