ReadLine() function.

dpkbahuguna · #1 (**permalink**) July 30th, 2009, 02:14 AM

Hello Friends,

There is a function StreamReader.ReadLine() to read the line from the Files. I want to know that If I have a File which has contents like this:
MyText.txt
This is first line.
This is secont line.
is the third line.

In this file there is a third line which has the 5 spaces in begining of the line but ReadLine function is reading only the TEXT it is not reading SPACES. Is there any way to Read spaces too.

Thanks !!!

If you are using asp.net with vb.net then try this

My.Computer.FileSystem.ReadAllText(FilePath)

let me try my best as i am working more on vb.net

after getting the entire textfile into string using stream reader then search for a line break and find out the lines

Environmetn.NewLine is the constant might be useful for you to split all the ines into a array using something like

textilecontent.split(Environmetn.NewLine )

try and let me know if it works

Hello pons_saravanan,

Thanks for you reply I think u did not get my question my question is not related to the Lines of the file contents..I am asking to read the spaces..

suppose ( * = space )

now what i want to do if there is line like this:
**********This is line.
This line has Ten speces from it's begining. Now I want to show this line at an ASP:Label and in the Label it should show as just it is I mean in label Text it should be start like [**********This is line.] but what is happening now in Label Text is starting like [This is line.]

cheers :)

Hi DPK...I was able to show spaces...but with a MultiLine TextBox.
See the below code if it helps you.
----------------------------------------

//Code Start
protected void Realwhole()
{
string thefile = Server.MapPath("tic.txt");
StreamReader srdr = default(StreamReader);
srdr = File.OpenText(thefile);
string someString = string.Empty;

while (srdr.Peek() != -1)
{
someString = srdr.ReadToEnd();
TextBox1.Text = someString;
}
srdr.Close();
}
//Code End

Browsers will not render multiple spaces like this. So if you assign

Code:

 
Label1.Text = "          this is a line starting with ten spaces";

the label text will show on the page with no spaces.

To show the spaces, you must convert them to non-breaking HTML spaces.

Code:

Label1.Text = "          this is a line starting with ten spaces".Replace(" ", "&nbsp;");
