ValueDe Cookie no debe ser null .The Value of a Cookie must not be null. Si null se asigna un valor a esta propiedad, se reemplaza por una cadena vacía.If a null value is assigned to this property, it's replaced with an empty string.

Los signos de punto y coma son caracteres reservados que no se pueden utilizar en el valor de esta propiedad.Semicolons and commas are reserved characters that cannot be used in the value of this property. La asignación de caracteres no válidos a esta propiedad no produce una excepción; pero al intentar agregar esto Cookie a una CookieContainer instancia con el Add método, se producirá un error en la operación y se producirá una excepción.Assigning invalid characters to this property doesn't throw an exception; but when you try to add this Cookie to a CookieContainer instance with the Add method, the operation will fail and throw an exception.
