Question

嗨，任何人都可以解释这些代码行，我需要了解它是如何工作的，以便继续我正在做的事情

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);
     }

如果唯一要做的就是删除第一个和最后一个元素，我会使用LinkedList而不是List。

Answer 2

它将响应流作为字符串读取，假设字符串由逗号分隔的序列“{...}”组成，例如：

{X}，{Y}，{Z}

然后

将字符串拆分为“}，{”，给出一个

数组

{X

ý

Z}

然后从数组的第一个元素（{X =＆gt; X）中删除第一个大括号，从数组的最后一个元素（Z} =＆gt; Z）中移除结束大括号。

Answer 3

从我所看到的，它是从一个可能来自TCP的流中读取的。它读取整个数据块，然后使用分隔符},{分隔块。

因此，如果您有类似abc},{dec的内容，它将被置于具有2个值的split1数组中，split1 [0] = abc，split1 [1] = dec。

之后，它基本上删除了第一个和最后一个内容

Answer 4

正在处理错误输出。它收到了来自e的流（我想这是一个例外），读取它。它看起来像： “”{DDD}，{我失败}，{因为}，{没有信号} {ENDCODE} 它将其拆分为不同的字符串，并删除到第一个和最后一个条目（DDD，ENDCODE）
