StreamWriter and NewLine

Question

hallo everybody,

I want to create a text file by writing a single line at a time and use the following method.

FileStream fs = new System.IO.FileStream(file, System.IO.FileMode.Create,             System.IO.FileAccess.Write, System.IO.FileShare.None);

StreamWriter sw = new System.IO.StreamWriter(fs, System.Text.Encoding.Default);

sw.WriteLine("Line 1");

sw.Close();

Problem is that the text file contains two lines where the second line is empty. StreamWriter advances to next line after writing a line is the reason i think....

How can i create the text file without an empty line at the end of the file. ?

I don't want to use StringBuilder or any thing like that to create the text and write the whole content all together to the text file.

How can i do it ? I am using dot net 2.0

Thanks for any help in advance :-)

regards

Answer 1

The last time you write to the file, use Write instead of WriteLine.

WriteLine Writes a line terminator after string. use Write method as David suggests.

Somehow, yes.  

If you're in a loop and you have an array, here's an example:

for (int i = 0; i < array.Length - 1; i++) // note the minus 1

    writer.WriteLine(array[i]);

writer.Write(array[array.Length - 1]);
