Is there a need to process with ReadLine()? If you can process per bytes then you can use StreamReader.BaseStream and then you can get length from that.
If you need lines for whatever reason then i think your best a approach would be a quick loop through the file and count the line, a simple loop like the following should not take alot of processing time.
StreamReader sr = new StreamReader("file");
int lineCount = 1;
string line = sr.ReadLine();
while(line != null)
{
line = sr.ReadLine();
lineCount++;
}
sr.Close();
My opinion is... If someone has already posted an answer, dont post the SAME answer

int lines = File.ReadAllLines("filename").Length;
This should give you the number of lines. The entire file is buffered and so if the file is huge you could come into trouble. Else the loop mentioned by musefan is another option.
But still, your code is failing for the reason as I pointed out before.

Hi
I would like to know write C# code for accessing dongle

|

Just a guess, but you might want to look how to read/write from the port as you insert a dongle there.
But I never did it so I might be totally wrong

You asked this before. Google will help you. Or buy a book. Or ask a more specific question. Or maybe learn, how to do research at all before you start programming.

I have datagridview binded with data. datagrid columns are in AutoSort Mode. now i sort the grid with one column, say ProductId. int the datagrid i have procut id with "a,c,d".after sorting DESCENDING order the order is "d,c,a".Now i am adding new product , say "b". after adding i tab out from procut id cell. now, since that columns is alreay in sorted the product "b" goes in between "a" and "c" automatically. due to this behaviour i am loosing currentrow index.
Can any one post me solution how can i over come this issue.
what are the possible fixes to current row index.? or How can i restrict the behaviour of automatic data sort.?
Regards,
Prasad

At a guess, I never edit in a grid, you could turn the sort off when you start add/edit a row and turn it on when editing is completed.

I am having a DataGridView on a C# windows form, say frmOne, which has several rows of records on this DataGridView, what i want to do now is that when i click 1 row record out of those records in the DataGridView, how can i send the cell values to another form's textbox, say frmTwo. Below is an example:
On frmTwo:
txtClient.Text = frmOne.DataGridView.(whatever things that i dont know how to map at this stage).
Thanks in advance.

For goodness sake learn to use google or the MSDN Help.
for google 'pass data between forms c#' gets a whole shedload of hits.
next learn how to use a datagridview by the same method.
Then, AND ONLY THEN, ask a question when you have done some work and are actually stuck in your own code.

dude, i dont need this sort of instruction and if you dont know to plot a guidline for the other members in here, i doubt you should be here. Why don't you just go to the place that really belongs to you, such as a forum for complaining etc.
Guess what, i fixed myself just after 30 mins i posted the message. And i am willing to share my knowledge with others as long as they shoot me an email if they go the similar issues.
