C # reads the contents of the. config file

Today in the project, because the program at the same time to start a variety of data, the test is divided into more than one person, you need to separate the data, so with a temporary configuration file, let the test in the configuration file to modify the corresponding data so that each test does not affect each other!

Steps:

First step: Add an app. Config file with the following file format:

<?xml version= "1.0" encoding= "Utf-8"?>
<configuration>
<appSettings>
<add key= "Canshu" value= "hkg999$sha777!1002*1003#sha888!0001*0002"/>
</appSettings>
</configuration>

This is an example I used when testing!

Second step: Add the file to the project.

At first I was using this method to read:

String Ceshi =configurationmanager.appsettings["Canshu"];

Note: You need to add the System.Configuration in the Resource Manager reference, and then add the using System.Configuration in the code;

Now the problem is, if you have this app. config file is not in your startup entry under the directory, so you can not get the data you want, return a null.

Workaround: (Get profile data below the absolute path)

The following is a better use of this method:

Execonfigurationfilemap map = new Execonfigurationfilemap ();
Map.   Execonfigfilename = @ "app. Config"; ////(@ "" in the quotation marks is the absolute path of your configuration file in the program).
Configuration config = configurationmanager.openmappedexeconfiguration (map, Configurationuserlevel.none);
string Ceshi = config. appsettings.settings["Canshu"]. Value;

This way you get the data you want! I hope to meet the same problem of beginners like me can get help!
