从 StreamReader 获取剩余内容

发布于 2024-12-01 04:46:02 字数 527 浏览 0 评论 0原文

我有一个流读取器，用于从流中读取行。这很好用，但是我希望能够获得最后一行，该行永远不会以换行符结束，因此 readLine() 不会捕获它。

我将把它存储为一个全局变量，并在下次运行之前附加到流中。

这有可能吗？

void readHandler(IAsyncResult result)
{
    tcpClient = (TcpClient)result.AsyncState;
    StreamReader reader ;
    string line;
    using (reader = new StreamReader(stream))
    {
        while((line = reader.ReadLine()) != null){
            System.Diagnostics.Debug.Write(line);
            System.Diagnostics.Debug.Write("\n\n");
        }

    }
    getData();
}

原文

I have a stream reader that I am using to read lines from a stream. This works well however I would like to be able to get the last line which will never end with a line break so the readLine() will not capture it.

I will store this is a global variable and append to the stream before the next run.

Is this possible at all?

void readHandler(IAsyncResult result)
{
    tcpClient = (TcpClient)result.AsyncState;
    StreamReader reader ;
    string line;
    using (reader = new StreamReader(stream))
    {
        while((line = reader.ReadLine()) != null){
            System.Diagnostics.Debug.Write(line);
            System.Diagnostics.Debug.Write("\n\n");
        }

    }
    getData();
}

ReadLine 确实捕获流的最后一行，即使后面没有换行符。例如：

using System;
using System.IO;

class Test
{
    static void Main()
    {
        string text = "line1\r\nline2";

        using (TextReader reader = new StringReader(text))
        {
            string line;
            while((line = reader.ReadLine()) != null)
            {
                Console.WriteLine(line);
            }
        }
    }
}

打印：

line1
line2

ReadLine() 将仅在到达流末尾并返回全部时返回null > 的数据。

ReadLine does capture the final line of the stream even if it doesn't have a line-break after it. For example:

using System;
using System.IO;

class Test
{
    static void Main()
    {
        string text = "line1\r\nline2";

        using (TextReader reader = new StringReader(text))
        {
            string line;
            while((line = reader.ReadLine()) != null)
            {
                Console.WriteLine(line);
            }
        }
    }
}

Prints:
