没有自动设置器/获取器的C#中的设置列表项 [英] Setting List items in C# without automatic setter/getter

问题描述

我正在尝试在C#中创建一个手动的setter/getter方法，但是我从"set"行中遇到了以下错误: 错误:"System.Collections.Generic.ListPackage.Add(Package)"的最佳重载方法匹配具有一些无效参数

I'm trying to make a manual setter/getter method in C#, but i'm getting the following error from the "set"-line: Error: The best overloaded method match for 'System.Collections.Generic.ListPackage.Add(Package)' has some invalid arguments

private List<Package> packages = new List<Package>();    

public List<Package> Packages
{
    set { packages.Add(value); }
    get { return packages; }
}

推荐答案

您的代码应如下所示.

Your code should look like this.

private var packages = new List<Package>();    

public List<Package> Packages
{
    set { packages = value; }
    get { return packages; }
}

如果您尝试使用索引getter/setter进行某种传递:

If you're trying to use the index getter/setter for some kind of passthrough:

public int this[int key]
{
    get
    {
        return Packages[key];
    }
    set
    {
        Packages[key] = value;
    }
}
