推荐答案

您可以创建TextReader包装器，该包装器将跟踪基础TextReader中的当前位置:

公共类TrackingTextReader:TextReader
{
私人TextReader _baseReader;
private int _position;

公共TrackingTextReader(TextReader baseReader)
{
_baseReader = baseReader;
}

公共重写int Read()
{
_position ++;
返回_baseReader.Read();
}

公共重写int Peek()
{
返回_baseReader.Peek();
}

public int位置
{
得到{return _position; }
}
}

然后，您可以按以下方式使用它:

字符串文本= @"Foo
酒吧
巴兹
布拉
Fasel"；

使用(var reader = new StringReader(text))
使用(var trackingReader = new TrackingTextReader(reader))
{
字符串行；
while((line = trackingReader.ReadLine())！= null)
{
Console.WriteLine("{0:d3} {1}"，trackingReader.Position，line);
}
}

You could create a TextReader wrapper, which would track the current position in the base TextReader :

public class TrackingTextReader : TextReader
{
private TextReader _baseReader;
private int _position;

public TrackingTextReader(TextReader baseReader)
{
_baseReader = baseReader;
}

public override int Read()
{
_position++;
return _baseReader.Read();
}

public override int Peek()
{
return _baseReader.Peek();
}

public int Position
{
get { return _position; }
}
}

You could then use it as follows :

string text = @"Foo
Bar
Baz
Bla
Fasel";

using (var reader = new StringReader(text))
using (var trackingReader = new TrackingTextReader(reader))
{
string line;
while ((line = trackingReader.ReadLine()) != null)
{
Console.WriteLine("{0:d3} {1}", trackingReader.Position, line);
}
}
