Server.MapPath 和 window.open()

Question

I'm actually working on an app that provides the possibility to the users to upload the files they wish. Those files should also be visualizable once uploaded.

In order to do that I'm trying to get the file path with Server.MapPath and a concatenation of other values. The file path is passed as an argument in a window.open javascript function.

My problem is that I do not get any result at all. No window is opened.

Here is my code:

string completeUrl = Server.MapPath(ConfigurationManager.AppSettings["UsersImagesUploadFolder"] + CurrentUserLogin +
                               @"\\" + ((GridDataItem) e.Item)["Url"].Text);

string radWindowOpen = "<script type='text/javascript'>window.open('" + completeUrl + "')</" + "script>";
 Page.ClientScript.RegisterStartupScript(this.GetType(), "fileDisplay", radWindowOpen);

I'm probably missing something obvious but I don't see what it is.

Thank you for your answers.

As Damien has pointed out, Server.MapPath is used for server side path mapping. Clients need to see a path underneath your web app.

For example:

Page.ResolveUrl("~/uploads/" + ConfigurationManager.AppSettings["UsersImagesUploadFolder"] ...

Would resolve a to http://mydomain/vroot/uploads/... etc.

As an aside, note also that @"\\\\" would result in a double backslash, which I don't think you intended.

Either of @"\\" or "\\\\" would result in a single backslash.
