解釋碼

Question

嗨誰能解釋代碼的這些行，我需要了解它是如何工作才能繼續進行我在做什麼

if (e.Error == null){ 
    Stream responseStream = e.Result; 
    StreamReader responseReader = new StreamReader(responseStream); 
    string response = responseReader.ReadToEnd(); 

    string[] split1 = Regex.Split(response, "},{"); 
    List<string> pri1 = new List<string>(split1); 
    pri1.RemoveAt(0); 
    string last = pri1[pri1.Count() - 1]; 
    pri1.Remove(last); 
} 

Answer 1

// Check if there was no error 
    if (e.Error == null) 
    { 

// Streams are a way to read/write information from/to somewhere 
// without having to manage buffer allocation and such 
     Stream responseStream = e.Result; 

// StreamReader is a class making it easier to read from a stream 
     StreamReader responseReader = new StreamReader(responseStream); 

// read everything that was written to a stream and convert it to a string using 
// the character encoding that was specified for the stream/reader. 
     string response = responseReader.ReadToEnd(); 

// create an array of the string by using "},{" as delimiter 
// string.Split would be more efficient and more straightforward. 
     string[] split1 = Regex.Split(response, "},{"); 

// create a list of the array. Lists makes it easier to work with arrays 
// since you do not have to move elements manually or take care of allocations 
     List<string> pri1 = new List<string>(split1); 
     pri1.RemoveAt(0); 

// get the last item in the array. It would be more efficient to use .Length instead 
// of Count() 
     string last = pri1[pri1.Count() - 1]; 

// remove the last item 
     pri1.Remove(last); 
    } 

我會用一個LinkedList而不是List如果要做的唯一事情就是刪除第一個和最後一個元素。

Answer 2

從我所看到的，它是從一個流讀取可能來自TCP。它讀取整個數據塊，然後使用分隔符},{分隔塊。

因此，如果您有類似abc},{dec的東西，它將被放置到具有2個值的split1數組中，split1 [0] = abc，split1 [1] = dec。

之後，它基本上除去第一和最後一個內容

Answer 3

它正在處理錯誤輸出。 它從e收到一個流（我猜這是一個例外），讀它。 它看起來像這樣： 「{DDD}，{我失敗}，{因爲}，{沒有信號} {ENDCODE} 它將它分成不同的字符串，並刪除到第一個和最後一個條目（DDD，ENDCODE ）

Answer 4

它讀取響應流作爲一個字符串，使該字符串由序列的假設 「{...}」 之間用逗號分開，例如：

{X}，{Y}，{Z }

然後分裂的字符串 「}，{」，給人的

{X

陣列

ý

Z}

然後刪除該數組的第一個元素的第一括號（{X => X）和從陣列的最後一個元素的端部支柱（Z} =>ž ）。
