Hi The following code uses StreamWriter to write the contents of a DataTable to a text file. How do I read the contents of this file into an Excel spreadsheet using streamwriter? You have your dataset still in your memory when you perform mAdapter.Fill(dt) A small example below. Write To Text File Using Streamwriter C#Append lines to a file using a StreamWriter. Ask Question. Writing in a specific line in text file using streamwriter in c#. StreamWriter only writes one line. First, let's create a new text file and write something into it.

Now, go ahead and add using System.IO into the source code. Next, we'll create a using block and.
![]() Good day to all, I am very much new to programming and C#. I have a problem in writing a new line to a text file. I am using a streamwriter to create a new text file and write data to it. See More On MSDNEverytime, I add a newline to textfile, it should be like below: John;1234;somedata;somedata Lily;2213;somedata;somedata however, my code wont do the above, the output in the text is John;1234;somedata;somedataLily;2213;somedata;somedata which is not what i want. Please show me the correct way to fix this problem. I will be very appreciated. Your original post suggested that you wanted the output to look like: John;1234;somedata;somedata Lily;2213;somedata;somedata To do that, use WriteLine('John;1234;somedata;somedata') WriteLine('Lily;2213;somedata;somedata') If what you actually wanted is John 1234 somedata somedata Then Writeline will still help, but you need to do a bit more work. ![]() First, why add up all the textboxes if you want to write them to the file piece by piece? Eg what wrong with WriteLine(text1.text) WriteLine(text2.text) etc? If you must start with 'John;1234;somedata;somedata' then perhaps you could look into using the Replace() function to swap all the semicolons for r n end of line sequences. Thanks you for taking your time reply to my post. I got this working last nite already. What my program does is, take input from several text box and write it to a single line. Every time a button add is clicked, a new line will be added. Give More FeedbackI did use the writeline method and this time it's worked. My only problem now is how to search for data in a line by using one of its text field. For example: here is the data in text file John;1234;Sydney;Aus Timy;3214;Melbourne;Aus Lana;8471;Darwin;Aus now i want to bring up all of timy's data by searching for 'timy'. I know I have to use some kind of loop for this function, but i not so sure how to? Windows controller drivers. Any suggestion will be a great help for me.
