你知道为什么会这样吗:

    public struct UserNameAndPassword
    {
        public string username;
        public string password;
    }


    [HttpPost]
    public IActionResult Create([FromBody]UserNameAndPassword usernameAndPassword)
    {
        Console.WriteLine(usernameAndPassword);
        if (this.AuthenticationService.IsValidUserAndPasswordCombination(usernameAndPassword.username, usernameAndPassword.password))
            return new ObjectResult(GenerateToken(usernameAndPassword.username));
        return BadRequest();
    }

但是当我用元组替换它时,这不起作用？

     [HttpPost]
    public IActionResult Create([FromBody](string username, string password) usernameAndPassword) //encrypt password?
    {
        Console.WriteLine(usernameAndPassword);
        if (this.AuthenticationService.IsValidUserAndPasswordCombination(usernameAndPassword.username, usernameAndPassword.password))
            return new ObjectResult(GenerateToken(usernameAndPassword.username));
        return BadRequest();
    }

usernameAndPassword.username和.password都为null.

你不被允许在控制器中使用元组吗？
