Question

I have a text box and a button in a form.i want to save a file into the network path entered in the textbox while clicking the button. i tried the code given below.

 private void button1_Click(object sender, EventArgs e)
    {
        string destinationPath = txtFilePath.Text.ToString();
        string sourceFile = @"c:\1.txt";
        string fileName = Path.GetFileName(sourceFile);
        System.IO.File.Copy(sourceFile, Path.Combine(destinationPath, fileName));

    }

it works fine if the destination provided the permission to change content. If the destination is ‘read only’ then it gives the error. if the input is \192.168.0.24\aqm , then it shows the error shown below (the path do not have write permission)

Access to the path ‘\192.168.0.24\aqm\1.txt’ is denied.

is there anyway to solve this. i mean, if the destination is read only, then it prompt username and password of that system , if username password entered correct, then save the file to that directory . the user knows the username and password of all the computers in the network. cant give write permission to every system casue of some security reason. thats why i am looking for a method i suggested above

or any other ways??
Hope someone help me

I can suggest you to another way. If it possible, make a Windows Service. Set Service Log On to account which ahve Admin permissions. Make your copy process with Windows Service. I am using this algorithm in one of my projects. It works great, if the service logs in with Admin credentials. The computer have Windows Service with Admin Credentials can easly copy a file on any network machine. For ex, put a System Timer in your service. Let the service checks a path every 5 minutes. If there is a file exist in the given path, take file and copy to network machine by giving path.
