Este método se utiliza para convertir el valor de la string especificada en su carácter Unicode equivalente.
Sintaxis:
public static char Parse (string s);
Aquí, s es una string que contiene un solo carácter o nulo.
Valor de retorno: este método devuelve un carácter Unicode equivalente al carácter único en s .
Excepciones:
ArgumentNullException: si s es nulo.
FormatException: si la longitud de s no es 1.
Los siguientes programas ilustran el uso del método Char.Parse(String):
Ejemplo 1:
// C# program to demonstrate the
// Char.Parse(String) Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// calling Parse() Method
get("1");
get("a");
get("@");
get("-");
}
catch (ArgumentNullException e) {
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
catch (FormatException e) {
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
// Defining get() method
public static void get(string s)
{
// getting Unicode character
// using Parse() Method
char val = Char.Parse(s);
// display the char value
Console.WriteLine("Unicode character "+
"of string {0} is {1}", s, val);
}
}
Producción:
Unicode character of string 1 is 1 Unicode character of string a is a Unicode character of string @ is @ Unicode character of string - is -
Ejemplo 2: para ArgumentNullException
// C# program to demonstrate the
// Char.Parse(String) Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// calling Parse() Method
get("1");
get("a");
get("@");
get("-");
Console.WriteLine("");
Console.WriteLine("s is null");
get(null);
}
catch (ArgumentNullException e) {
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
catch (FormatException e) {
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
// Defining get() method
public static void get(string s)
{
// getting Unicode character
// using Parse() Method
char val = Char.Parse(s);
// display the char value
Console.WriteLine("Unicode character of"+
" string {0} is {1}", s, val);
}
}
Producción:
Unicode character of string 1 is 1 Unicode character of string a is a Unicode character of string @ is @ Unicode character of string - is - s is null Exception Thrown: System.ArgumentNullException
Ejemplo 3: para FormatException
// C# program to demonstrate the
// Char.Parse(String) Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// calling Parse() Method
get("1");
get("a");
get("@");
get("-");
Console.WriteLine("");
Console.WriteLine("The length of s is not 1.");
get("null");
}
catch (ArgumentNullException e) {
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
catch (FormatException e) {
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
// Defining get() method
public static void get(string s)
{
// getting Unicode character
// using Parse() Method
char val = Char.Parse(s);
// display the char value
Console.WriteLine("Unicode character of "+
"string {0} is {1}", s, val);
}
}
Producción:
Unicode character of string 1 is 1 Unicode character of string a is a Unicode character of string @ is @ Unicode character of string - is - The length of s is not 1. Exception Thrown: System.FormatException
