Read next line without consuming this using streamreader.

Question

hi guyes,
              my need is to read the next line data and check the particular character(i.e ;) in that data from file when i read the current line
              without consuming next line by streamreader();

Answer 1

hi,

To do this you have to read whole file first using File.ReadAllText methods

try..

string text = System.IO.File.ReadAllText(@"D:\textfile.txt");
var allText = text.Split(new string[] { "\r\n" }, StringSplitOptions.None);

for (var i = 0; i <= allText.Count(); i++)
{
    string line = allText[i];
    string nextline = allText[i + 1]; // put here validation if it is not exceed the array limit.

    //do your code.
}

hope this will help you.

If you don't want to read the second line at all if it starts with a ';'  then try this:

     using (StreamReader sr = new StreamReader("atul.txt"))
     {
       int i;
       int c = (int)';';
       string line = null; 

       while ((i = sr.Peek()) > 0)
       {
         if (i == c) break;
         line = sr.ReadLine();
         // code to insert line data into database
       }
     }

no

Answer 5

Something like this perhaps?

using (StreamReader sr = new StreamReader("somefile.txt"))

{

    string line;

    while ((line = sr.ReadLine()) != null)

    {

       if (line.Contains(";")) continue;

       // code to insert line data into database

    }

}

If the '; 'will only appear as the first character of a line, you could also use line.StartsWith(";").
