避免太多，否則，否則，如果聲明多個（9）條件

我有我的if else語句的條件，我想有沒有其他的替代解決方案，使代碼乾淨和短。所有9條件對asp.net mvc視圖執行不同的計算。我已經包括了代碼和圖像，顯示的一些情況來看，希望這是有意義的，我一直在尋找什麼更好的和可靠的解決方案對於這種情況..謝謝避免太多，否則，否則，如果聲明多個（9）條件

它看起來像頭盔發生的事情不會改變任何你做的車庫（獨立操作=>使用2個案例陳述）。所以你只需要做3 + 3 = 6支票而不是3 * 3 = 9支票。也困惑......你有兩個不同的變量具有相同的註釋，它是唯一看起來不同的空字符串和空情況。 –

我建議你研究一下如何避免太多ifs，因爲這是你的第二個問題。 – Reniuz

@yeh Renius，但我沒有得到更好的答案，所以我簡單解釋了這一個與圖像，nd得到太多的答案，將研究所有的解決方案thnx每個人。 –

首先，移動窗體值的提取到方法的開頭，如：

int? helmets = formvalues["helmets"] == null ? 
    null : Convert.ToInt32(formvalues["helmets"]; 
int? garages = formvalues["garages"] == null ? 
    null : Convert.ToInt32(formvalues["garages"];

然後你可以或許很容易設置的屬性沒有任何IFS /其他IFS，例如：

ViewBag.hideHelmet = helmets; 
// or 
someOtherProperty = helmets == null ? ... : ...

更新（關於你的評論/問題）：

在聲明x = condition ? value1 : value2中的?:運營商稱爲conditional operator。如果condition爲真，則返回value1，否則返回value2。
int?是一個nullable integer，它可以有一個整數值或爲空。

你能解釋一下我的聲明：int？頭盔= formvalues [「頭盔」] == null？ null：Convert.ToInt32（formvalues [「helmets」]; –

'int？'是一個可爲空的整數：如果沒有找到帶有「helmets」鍵的formvalue，則將'helmets'設置爲null，否則設置爲formvalues中的值 – M4N

然後你可以檢查頭盔是否有值：'如果頭盔有.HasValue ...' – M4N

當然1你可以做的事情是改善你寫條件的方式。我認爲你可以通過將條件提取到方法來描述支票的實際操作，而不是在任何地方添加評論，這樣可以更好地服務。

OP可以將if塊中的語句提取到自己的方法中。這將顯着清理代碼。 – FishBasketGordo

所有條件都做了一些計算，例如在條件1中，沒有選擇任何內容，因此不進行計算，並且在發佈頁面時都會隱藏下拉列表。也是唯一的總價格數量沒有任何額外的價格的頭盔或車庫，因爲他們沒有選擇。 –

爲什麼不把注意力集中在分配目標而不是條件上？

該condidition似乎很簡單，重複。一個樣本：

ViewBag.hideHelmet = formvalues["helmets"] == ""? 1 : 0;

這不需要任何分支邏輯。

你能解釋一下你使用的運營商嗎？ –

@Mr A：'條件？ first_expression：second_expression;'是[條件運算符]（http://msdn.microsoft.com/en-us/library/ty67wk28（v = vs.80）.aspx） – sehe

，因爲你沒有在所有情況下都設置的值你可以與某些參數移動

ViewBag.hideHelmet = 1;//for jquery, This value is passed to jquery script which then decides which field to hide/show    
ViewBag.hideGarages = 1;//for jquery, This value is passed to jquery script which then decides which field to hide/show    
ViewBag.SelectedHelmets = 1;//    
ViewBag.SelectedGarages = 1;//    
ViewBag.TotalHelmets = 1;    
ViewBag.TotalGarages = 1;    
ViewBag.TotalAmount = 1;    
ViewBag.TotalAmount = trackEventCost.UnitCost;

要在方法optional。其次，你可以使用ternary operator。你可以使用像三元運算符。

int r = 1; 
    long l = r == 1 ? 1 : (r==2 ? 2 : (r==3?3:(r==4 ? 4 : 5)));

您可以將您的ViewBag抽象爲設置所有數據的函數。這會稍微清理一些東西。

if(...) { 
    SetUpViewBag(...); } 
else { 
    SetUpViewBag(...); } 

... 

private SetUpViewBag(...) 
{ 
    ViewBag.SelectedHelmets = prop1; 
    ViewBag.SelectedGarages = prop2; 
    ViewBag.TotalHelmets = prop3; 
    ViewBag.TotalGarages = prop4;

    ViewBag.hideGarages = prop6; 
    ViewBag.TotalAmount = prop7;

看看在Strategy模式，對於你的情況，你必須使用每個戰略每個策略的方法，而不是類。

void ApplyStrategy(int? helmets, int? garages) 
{ 
// depends on values of helmets and garages execute appropriate strategy 
} 

void ApplyNoHelmetsNoGaragesStrategy() 
void ApplyNoGaragesStrategy() 
void ApplyNoHelmetsStrategy() 
// ...

雖然您對策略模式是正確的，但我認爲這不會對OP有所幫助。嘗試給出OP如何用策略模式重構他的代碼的例子。 – Steven

太多的答案，我必須通過所有的答案，看看哪一個更好，我希望我是在csharp gud .. –

怎麼樣構建一個條件類

public class Condition 
{ 
    public Func<bool> Match { get; set; } 
    public Action Execute { get; set; } 
}

和bulid列表

 var conditions = new List<Condition> 
     { 
      new Condition 
       { 
        Match =() => formvalues["helmets"] == "" && formvalues["garages"] == "", 
        Action =() => 
           { 
             ViewBag.hideHelmet = 1;  
             ViewBag.hideGarages = 1; 
             ViewBag.SelectedHelmets = 1; 
             ... 
           } 
       }, 
      new Condition 
       { 
        ... 
       } 
     };

然後LINQ：

conditions.Where(c => c.Match()).ToList().ForEach(c => c.Execute());

一些GRE在建議。我喜歡處理這些情況如下。我重構了您的代碼以完全刪除條件。相反，我已經將每個條件的代碼封裝到一個方法中，並使用int類型的鍵和Action類型的值創建了一個散列表。我已經爲每個頭盔/車庫組合派生出一個獨特的價值，然後將其用作相應方法的關鍵。

我已經包含了不在你的文章中的代碼位的虛擬實現，以便我可以編譯和運行我的重構示例。希望有所幫助。
