您可以使用 void 做為 方法 的傳回類型 (或 區域函數) 來指定方法不會傳回值。You use void as the return type of a method (or a local function) to specify that the method doesn't return a value.
public static void Display(IEnumerable<int> numbers)
{
if (numbers is null)
{
return;
}
Console.WriteLine(string.Join(" ", numbers));
}
您也可以使用 void 做為參考型別來宣告未知類型的指標。You can also use void as a referent type to declare a pointer to an unknown type. 如需詳細資訊，請參閱指標類型。For more information, see Pointer types.
您無法使用 void 做為變數的類型。You cannot use void as the type of a variable.
