c# - C# 中的嵌套 If Else 语句

Question

我有一个检查枚举状态的嵌套 if else 语句

if ( status == enum.value1) 
{
    //Call some function 1 
}
else if ( status == enum.value2) 
{
    //call some function 2
}
else if ( status == enum.valu3 ) 
{
   call some function 3. 
}
else if ( status == enum.valu3  || status == enum.valu10) 
{
   call some function 4. 
}

我该如何重构/简化它？我不想使用 swicth 案例。

Answer 1

Try a Dictionary. Fill it up with delegates:

Dictionary<YourEnum, Action> dict = new Dictionary<YourEnum, Action>();
dict.Add(YourEnum.value1, MyMethod1);
dict.Add(YourEnum.value2, MyMethod2);
//etc.

And then return them plus invoke them when needed:

dict[myEnumValue]();

Answer 2

If you have a large amount of options, to the point where several ifs or a switch statement is inconvenient, you could create a Dictionary with the enum type as the key and a delegate as the value.

Answer 3

没有办法（据我所知）简化您的代码模式。这似乎没有问题，因为它已经非常简单了。
