Hello, I am using StreamReader.ReadLine() to read a text file.

I need a way to move the "pointer" back to the BOF (Beginning of File)
without having to close the object and create a new instance.

Is there any way of doing this? or is there another class within the
framework that will allow me to achieve this?

Any thoughts/ideas would be greatly appreciated

Thanks

JT.

I believe you have to close and then re-opend the StreamReader. You
shouldn't have to make a new instance though.

Not too sure of how do I re-open the StreamReader....

do you mean this?:

TextReader tr = new StreamReader("c:\\test.txt");
tr.ReadLine() //read line 1
tr.ReadLine() //read line 2
tr.close();
tr = new StreamReader("c:\\test.txt");
tr.ReadLine() //read line 1

If that's what you mean I think I am still creating a new instance
though

Cheers

Haven't tried this myself, but I think this should work:

StreamReader sr;
...
sr.BaseStream.Seek(0, SeekOrigin.Begin);
sr.DiscardBufferedData();
...
