C＃ - 代码分析2227困惑

问题描述

限时删除！！

我有一个类属性，如下所示：

I have a class property that looks as follows:

public List<Recipe> RecipeList
{
    get { return this._recipeList; }

    set
    {
        this._recipeList = value;
        OnPropertyChanged("RecipeList");
    }
}

在另一种方法我有一个引用的财产以下以上。

In another method I have the following which references the property above.

private void RecipeSearch()
{
            this.RecipeList = RecipeManagerService.SearchByUnit(SearchCriteria)
                               .Where(recipe => recipe.IsApproved == true && !recipe.IsHidden).ToList();
}

代码分析是发出CA 2227警告：更改RecipeList被只读通过删除二传手。谁能告诉我，为什么

Code Analysis is issuing a CA 2227 warning: Change RecipeList to be read-only by removing the setter. Could anyone tell me why?

推荐答案

添加一个公共setter方法上的列表< T> 对象是危险的。您可以消除通过这个警告你的二传手私人：

Adding a public setter on a List<T> object is dangerous. You can eliminate this warning by making your setter private:

public List<Recipe> RecipeList
{
    get { return this._recipeList; }

    private set
    {
        this._recipeList = value;
        OnPropertyChanged("RecipeList");
    }
}

这仍然可以让你的类来更改这个方法，但没有外部源。

This will still allow your class to change this method, but no external source.
