Re: Read text file to a certain point

C# Syntax (Toggle Plain Text)
StreamReader sr = new StreamReader("yourFileNameGoesHere", System.Text.Encoding.Default);
			string s = null;
 
			while ((s = sr.ReadLine()) != null)
			{
				if (s.IndexOf("fn:") != -1)
				{
					// ok, you found it
					// now you can do like 
					// textBox1.text = s;
					break;
				}
			}
 
			sr.Close();
StreamReader sr = new StreamReader("yourFileNameGoesHere", System.Text.Encoding.Default);
			string s = null;

			while ((s = sr.ReadLine()) != null)
			{
				if (s.IndexOf("fn:") != -1)
				{
					// ok, you found it
					// now you can do like 
					// textBox1.text = s;
					break;
				}
			}

			sr.Close();

Re: Read text file to a certain point

Grretings:
Just remove that part from the string:

C# Syntax (Toggle Plain Text)
s.Remove(0,3);
s.Remove(0,3);

the remove method takes two parameter, the index where you want to start removing and length you wish to remove

Re: Read text file to a certain point

Hi

Complete code to reading last line in text file

StreamReader streamReader = new StreamReader("HereWillBeYourTextFilePath");
ArrayList lines = new ArrayList();

string line;

while ((line = streamReader.ReadLine()) != null)
{
lines.Add(line);
}
streamReader.Close();

if (lines.Count > 0)
{
Response.Write(lines[lines.Count - 1].ToString());
}

===============
