Why would you even assume it could be found there. The paths like "C:\" are not even legal.

Web applications are being executed in sandboxed environment which prevents damaging the host systems. Your files can only be accessed if they are placed under the root directory configured for your site. For the location of the file in your host file system, you can call the method MapPath:
http://msdn.microsoft.com/en-us/library/system.web.httpserverutility.mappath.aspx[^].

And, come on, you server host may have no the idea even on what the "drive C:" is :-).

Sir please tell so How can I specify path ?

Sergey Alexandrovich Kryukov 9-Oct-13 9:36am

What do you mean by specify? You know better where could you put that XML file, but it should be withing your site's root directory.
You know this path relative to some ASP.NET page, but reading it requires absolute path, which you can get by calling MapPath.

Sir my code for file path is
string pathToFiles = Server.MapPath(@"C:\Form Data.xml");

My project files saved in C drive
So How to give absolute path ? sir please help me

Member 10272175 10-Oct-13 9:57am

My code is like sir

protected void Page_Load(object sender, EventArgs e)
{
string pathToFiles = Server.MapPath(@"C:\Form Data.xml");

Panel1.Visible = false;
Panel2.Visible = false;

Panel6.Visible = false;
}
protected void Button1_Click(object sender, EventArgs e)
{
Panel1.Visible = true;
Panel2.Visible = true;

Panel6.Visible = true;
Button1.Visible = false;

XmlReader xmlRdr = XmlReader.Create(@"C:\Form Data.xml");

while (xmlRdr.Read())
{
if (xmlRdr.Name == "CompanyName")
{
Label13.Text = (Label13.Text == string.Empty) ? xmlRdr.ReadString() : Label13.Text;
}

Sergey Alexandrovich Kryukov 10-Oct-13 12:54pm

This is not what MapPath is supposed to do. Do you really understand the concept of "relative path"? You need to use something like Server.MapPath("Form Data.xml"), Server.MapPath("./Form Data.xml").
Look at the examples: http://msdn.microsoft.com/en-us/library/ms524632%28v=vs.90%29.aspx.

Also, keep in mind: there are no situations where hard-coding of the file path can be useful.

In Above code, I took as you suggested as
protected void Page_Load(object sender, EventArgs e)
{
server.MapPath("Form Data.xml");
}

protected void Button1_Click(object sender, EventArgs e)
{
Panel1.Visible = true;
Panel2.Visible = true;
Panel6.Visible = true;
Button1.Visible = false;

XmlReader xmlRdr = XmlReader.Create(".\Form Data.xml");
while (xmlRdr.Read())
{
if (xmlRdr.Name == "CompanyName") { Label13.Text = (Label13.Text == string.Empty) ? xmlRdr.ReadString() : Label13.Text;
}

Buut It shows error...Please help me to modify same

could not found file path

Sergey Alexandrovich Kryukov 11-Oct-13 16:20pm

Check it up thoroughly, nothing else. Firs, under the debugger, or using logging, try to see what path your code is trying to access. Then, look at the server host's file system to see if it's there. Fix either one or both. By the way, don't write ".\Form Data.xml", change it to "./Form Data.xml". Please look at my comment above: why did you mangled my correct '/' into incorrect '\'?! It should be in the same directory as the ASP.NET page using it.

Member 10272175 11-Oct-13 22:54pm

Yes Now I have taken corect one as still shows error could not found
'C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\Form Data.xml'.

protected void Page_Load(object sender, EventArgs e)
{ server.MapPath("./Form Data.xml");
}
protected void Button1_Click(object sender, EventArgs e)
{
XmlReader xmlRdr = XmlReader.Create("./Form Data.xml");
while (xmlRdr.Read())
{ if (xmlRdr.Name == "CompanyName") { Label13.Text = (Label13.Text == string.Empty) ? xmlRdr.ReadString() : Label13.Text; }

Get back to my previous comment, "thoroughly" part. Probably you are pretty close already.
