How may I store a file path in my program's app.config file?

I have written a C# program for saving and reading PDF files. The program saves the output files to the local computer's bin folder. I want my program to access files from a different computer.

I have heard about keeping a file path stored in the app.config of my program, but I don't know how to do this.

How may I store a file path in my program's app.config file?

First: Create or Add app.config to your solution:

<configuration>
   <appSettings>
     <add key="Path" value="C:\text.txt"/>
   </appSettings>
 </configuration>

Last: Inside your winForm wirte these code:

string str= System.Configuration.ConfigurationManager.AppSettings["Source"];
            MessageBox.Show(str);
MessageBox.Show(str);

That is allllll

I'm a complete noob but I recently had the same issue so here is what I came up with.

The solution is three separate steps:

  1. As stated in the answer above, you add a key value to app.config that points to your path:

     <configuration>
   <appSettings>
     <add key="Path" value="C:\text.txt"/>
   </appSettings>
 </configuration>

  2. You need the using statement:

    using System.Configuration;

Besides these two, you also need a reference to the assembly.

  1. Right click on References in Solution Explorer.
  2. Click Add Reference.
  3. Click on Assemblies and type Configuration in the search box.
  4. Put a check mark on System.Configuration.

The message

ConfigurationManager does not exist in the current context.

should be gone and you have your file path!

You can store the file path in an app.config file by using this format:

<configuration>
 <appSettings>
  <add key="Path" value="\\ComputerName\ShareName"/>
 </appSettings>
</configuration>

You can then read the app settings stored there using the ConfigurationManager class. You'll have to add a reference to System.Configuration in your project, and reference it in the code.

After that, your path can be read by accessing ConfigurationManager.AppSettings["Path"] - it will be a string.
