Solution 1

Full path of the file can be access by using below function

C#

string filepath = Path.getfilename (fileupload1.filename);

rgarding permission issue :
you need to set permission for everyone group on that folder with modify right. don't give full access but modify is needed to resolve the permission issue.

Hi ravikhoda, Thanks for your response. Regarding to get the full path I have used same, but I can't get full path because in some web browsers not allow to get full path since security concerns. Therefore, I need a solution to get file name full path using file uploader or any other methods (Cannot use openfiledialog in asp.net).

Second, I have provided all rights to the particular folder and I gave user name password but still that public token is occur.

Please help me.

You want full path right?
then user Server.MapPath("filename");
you have to know where your directory is located then you can do the such type thing, see below code may be help full to you ..
this.Server.MapPath("~/" + System.IO.Path.GetFileName(fileName))

raneshtiwari Thanks for your response, when I use this code this.Server.MapPath("~/" + System.IO.Path.GetFileName(fileName)) it's get programm located path + filename. This is not I want. I want is user upload their image path, that path I want, it will be anywhere in the hard drive. Please help me.
