在C#中是否有类似于PHPs list()的语言结构？

Question

PHP有一个语言结构list(),它在一个语句中提供多个变量赋值.

$a = 0;
$b = 0;
list($a, $b) = array(2, 3);
// Now $a is equal to 2 and $b is equal to 3.

C#中有类似的东西吗？

如果没有,是否有任何解决方法可以帮助避免像下面这样的代码,而不必处理反射？

public class Vehicle
{
    private string modelName;
    private int maximumSpeed;
    private int weight;
    private bool isDiesel;
    // ... Dozens of other fields.

    public Vehicle()
    {
    }

    public Vehicle(
        string modelName,
        int maximumSpeed,
        int weight,
        bool isDiesel
        // ... Dozens of other arguments, one argument per field.
        )
    {
        // Follows the part of the code I want to make shorter.
        this.modelName = modelName;
        this.maximumSpeed = maximumSpeed;
        this.weight= weight;
        this.isDiesel= isDiesel;
        /// etc.
    }
}

不,我担心没有任何好的方法可以做到这一点,像你的例子这样的代码经常被写入.太糟糕了.节哀顺变.

如果您愿意为了简洁而牺牲封装,那么在这种情况下您可以使用对象初始化器语法而不是构造函数:

public class Vehicle
{
    public string modelName;
    public int maximumSpeed;
    public int weight;
    public bool isDiesel;
    // ... Dozens of other fields.
}

var v = new Vehicle {
    modelName = "foo",
    maximumSpeed = 5,
    // ...
};
