Convert.ToInt32 Method (Char)
.NET Framework (current version)
Converts the value of the specified Unicode character to the equivalent 32-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
-
Type:
System.Char
The Unicode character to convert.
The ToInt32(Char) method returns a 32-bit signed integer that represents the UTF-16 encoded code unit of the value argument. If value is not a low surrogate or a high surrogate, this return value also represents the Unicode code point of 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.
