streamreader readline

StreamReader的ReadLine()方法用于从文本流中读取一行数据。该方法会读取数据流中当前行的数据，并将其作为一个字符串返回。可以通过循环调用ReadLine()方法来逐行读取文本流中的数据，直到遇到数据流的结尾，此时返回null。以下是一个使用StreamReader的ReadLine()方法的例子：

using (StreamReader sr = new StreamReader("file.txt"))
{
    string line = sr.ReadLine();
    while (line != null)
    {
        Console.WriteLine(line);
        line = sr.ReadLine();
    }
}

上述代码会打开名为“file.txt”的文件，并逐行读取其中的数据，并将每行数据输出到控制台。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
