如何在C＃中更新字典值; [英] How to update dictionary value in C#;

问题描述

I have 

Dictionary<int, myClass> ActiveTabIndex = new Dictionary<int, myClass>();
public class myClass
    {
        public int TabIndex { get; set; }
        public string OdSessionId { get; set; }
        public string TextBoxValue { get; set; }
    }

我是向字典添加值，例如 

ActiveTabIndex.Add(1, new myClass{ TabIndex = 1, OdSessionId = "S", TextBoxValue=""});

现在我想更新TextBoxValue键1， 
喜欢

ActiveTabIndex[1] = new myClass{ TextBoxValue="something"};

但它的其余部分值为默认值，

How Can I update The value of dictionary for the specific key with out overriding Other value.

推荐答案

将其创建为静态。但是将字典公开为公共使用它应该是错误的。使用封装原则来在字典中添加和获取值。这意味着你将实现public static void Add（myClass myClassObject）方法和public
static myClass GetmyClassObjectByKey（int key）方法来处理字典。

Create it as static. But it should be wrong to expose dictionary as public to work with it. Use encapsulation princip to Add and Get values to/from dictionary. It means you will implement public static void Add(myClass myClassObject) method and public static myClass GetmyClassObjectByKey(int key) method to work with dictionary.
