What is the environment variable concept?

In a C# program I need to call an executable. The executable will call some other executables that reside in the same folde

There are many types of environment variables, like system level and users. It depends on your requirements.

For setting environment variables, just use the Get Set method. Pass variables Name and Value as parameters and if use to define access level then must pass with it. For accessing the value then use the Set method to pass the access level parameter too.

For example, I am defining user-level variables:

//For setting and defining variables
System.Environment.SetEnvironmentVariable("PathDB", txtPathSave.Text, EnvironmentVariableTarget.User);
System.Environment.SetEnvironmentVariable("DBname", comboBoxDataBaseName.Text, EnvironmentVariableTarget.User);

//For getting
string Pathsave = System.Environment.GetEnvironmentVariable("PathDB", EnvironmentVariableTarget.User);
string DBselect = System.Environment.GetEnvironmentVariable("DBname", EnvironmentVariableTarget.User);
