C# 4.0 如何在C#中为类属性赋值？

我不熟悉C#编程，并尝试使用在“Car”、“Truck”类中继承的“Vihicle”接口属性编写以下程序。我面临的问题是这个错误：

发生“System.StackOverflowException”类型的未处理异常

我在将值分配给汽车属性时得到了这个值。以下是我的代码：

看看你的财产：

private string make;
public string Make  // read-write instance property
{
    get
    {
        return Make;
    }
    set
    {
        Make = value;
    }
}

当您从

Make

读取值时，它会在内部从

Make

读取值（与写入值相同），这会导致无限递归。您需要从保存该值的变量读取/写入：

private string make;
public string Make  // read-write instance property
{
    get
    {
        return make;
    }
    set
    {
        make = value;
    }
}

属性的内部逻辑不能引用自身。实际上必须有东西来存储该值

编辑：除非有任何特殊原因使用这样的属性（例如在getter/setter中需要更多逻辑），否则您可以使用自动生成的属性来简化代码。因此，您可以使用以下方法代替：

private string make;
public string Make  // read-write instance property
{
    get
    {
        return make;
    }
    set
    {
        make = value;
    }
}

您只需使用以下功能：

public string Make { get; set; }

编译器会自动将后者转换为与前者非常相似的内容（可能只是使用不同的支持变量名）.

感谢您的帮助。还有一件事，我是否应该将接口Vihicle属性添加到Truck类及其子类TowingTruck？？？因为继承者权限就像类Truck继承接口Vihicle类TowingTruck继承Truck感谢advance@HasanBadshah：继承类时，不需要重新实现继承的成员，否。

Truck

需要实现接口的成员，但是从

Truck

继承的任何东西都已经从

Truck

本身得到了实现。非常感谢你David:）
