Changing URL string before inserting with C#

[Eyadtrabulsi]

Hello, I'm new member, Please someone help me..

I got image's address using Server.MapPath and returned it to .ImageURL of the ImageButton but it didn't work
I noticed later that if I added \\\ 3 backslashs "as a string" at the bigining of the address it would work properly, so is there anyway to add backslash to a STRING in C#, because the compiler doesn't accept any backslash in "\\\" string formats
Or how could we edit string properly before we insert it into address
and what is the exact format of ImageURL strings

[avkdsiva]

Page.Response.Redirect(@"Dir1\Dir2\Mypage.aspx")
or
Page.Response.Redirect("Dir1\\Dir2\\Mypage.aspx")

Thank you very much for your answer, but I mean Image URL not the page's one
I used "C:\dir1\dir2\image.jpg"
but it didn't work, so I tried "\\\C:\dir1\dir2\image.jpg"
it worked..!!!!

Anyway, if I can edit the text after retriving it by using Server.MapPath, it would give me more flexibility...

Please someone helps me... I'm still waiting!!

[avkdsiva]

protected void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
Image1.ImageUrl = Server.MapPath("..\\Images\\BankName.JPEG");
}

I did this way and it is working. Please tell me if I am misinterpreting the question.

Thanks for you reply, but I would let you know what exactly I'm trying to do..

I have directory which contains all images I'm automating displaying them, by searching for them and returning them in an array to present them on my webpage
here is the code



int i = 0;
// get the address of the directory, then seach for files with .JPG extension inside
string add = Server.MapPath("pics//horses//");
string[] images = Directory.GetFiles(add , "*.jpg");

// Create ImageButton Array, and use it to store & present result images in determine specifications
ImageButton[] imageBtt = new ImageButton[images.Length];
foreach (string image in images)
{
Label1.Text += image;
imageBtt[i] = new ImageButton();
imageBtt[i].Width = 70;
imageBtt[i].Height = 47;
imageBtt[i].ID = "imageBtt" + i;
imageBtt[i].Visible = true;
imageBtt[i].ImageUrl = image;

ContentPlaceHolder3.Controls.Add(imageBtt[i]);
i++;
}


I used Lable1 to know exactly what is the address returning by this code, its correct as it's shown below:

C:\Documents and Settings\showroom\My Documents\Visual Studio 2005\HorseClub\pics\horses\cebit.jpg

but it's not showing the images by the ImageButtons, I'm wondering if it's because of the address format. What do you think??

[avkdsiva]

One simple (may be silly as well) question.
Can you modify the below line
string add = Server.MapPath("pics//horses//");
as
string add = Server.MapPath("pics\\horses\\");

and see what happens?
:)

[Eyadtrabulsi]

Sorry :-(
it gave the same results...

[Eyadtrabulsi]

but you know!!? such a format like this worked with ImageURL address:

\\\C:\Documents and Settings\showroom\My Documents\Visual Studio 2005\HorseClub\pics\horses\cebit.jpg

but I tried to add "\\\" to the begining of the address before inserting it into ImageURL but it didn't work, maybe the compiler rejects such a character \ as a string...

[Eyadtrabulsi]

Please someone gives more attention to my request, it very close to be solved...

Isn't there anyway to insert \ backslash into string with C#
This is the second community which stoped responding at this point

[avkdsiva]

string[] imgs = Directory.GetFiles("E:\\Projects\\Banking\\Images" , "*.jpg");
foreach (string img in imgs)
ImageButton1.ImageUrl = img ;

The above code is working fine.... I am not able to reproduce your problem.

But, we didn't stop responding! ;o)

There are two ways to insert a backslash:

1. As Avkdsiva did, you use two backslashes
2. But, that gets messy: if you have three backslashes, you have to use six. So, if you place an @ before the first quote, then you can place backslashes in the string:

MessageBox.Show(@"\\\C:\Documents and Settings\showroom\My Documents\Visual Studio 2005\HorseClub\pics\horses\cebit.jpg");
