c＃爲現有列表添加值<Class>

Question

試圖通過.NET文檔找到解決方案，但並未真正獲得或找到答案。

所以我定義一個類：

public class Hold 
    { 
     public DateTime Time { get; set; } 
     public Double PosX { get; set; } 
     public Double PosY { get; set; } 
     public Double avgTime { get; set; } 
    } 

然後我定義我的列表作爲List<Hold> data;

，並有時間列表，如List<DateTime> time;

我經過一個LINQ for循環並獲得價值爲3個領域時間，PosX和PosY

接下來我運行這個

foreach(Hold h in data) 
{ 
    time.add(h.Time); //Add to the List so we can look at the Time Field Further 

    for(int i =0; i < time.Count; i++) 
    { 
     double avg // Variable works out the time between Time Records in a Database their is some assignment code but sure if it is relevant to the question ? 
     data.add({ avgTime = avg}); <-- problem here as I want to add avg to my Data class List in the field of avgTime 
    } 
} 

Answer 1

我想你想設置的值爲h.avgTime，因爲h是你正在處理的當前元素。

foreach(Hold h in data) 
{ 
    time.add(h.Time); 

    for(int i =0; i < time.Count; i++) 
    { 
     double avg = 0; //Whatever calculation you want 
     h.avgTime = avg; 
    } 
}
