Read only the first few lines of text from a file
提问by Oliver Kucharzewski
How can I read just the first two lines of a file my program saves? (They represent a username and a password.)
如何仅读取程序保存的文件的前两行?(它们代表用户名和密码。)
采纳答案by Ry-
Use a System.IO.StreamReader.
string line1, line2;
using (StreamReader reader = new StreamReader("myFile.txt")) {
line1 = reader.ReadLine();
line2 = reader.ReadLine();
}
Or, for something modern:
或者,对于现代的东西:
var lines = File.ReadLines("myFile.txt").Take(2).ToArray();
回答by Maciej
For that use StreamReader.ReadLine()
为了那个用途 StreamReader.ReadLine()
