Represents the application directory where the current assembly is located.
public static string ApplicationDirectory { get; }
The ApplicationDirectory property provides a robust way to get the directory path for the currently executing assembly. This is particularly useful for scenarios where your application needs to access resources or configuration files located relative to its own executable. Unlike using AppDomain.CurrentDomain.BaseDirectory, CAS.ApplicationDirectory is designed to be more resilient in certain deployment scenarios, such as when using ClickOnce or other deployment technologies that might alter the perceived base directory.
It is recommended to use this property for obtaining the application's root directory when dealing with file system operations that are relative to the application's installation location.
The following C# code example demonstrates how to use the ApplicationDirectory property to construct a file path to a configuration file named appsettings.json located in the same directory as the application's executable.
using System;
using System.IO;
using System.Net.Security; // Assuming CAS is part of System.Net.Security for this example
public class Example
{
public static void Main()
{
try
{
string appDir = CAS.ApplicationDirectory;
string configFilePath = Path.Combine(appDir, "appsettings.json");
Console.WriteLine($"Application directory: {appDir}");
Console.WriteLine($"Configuration file path: {configFilePath}");
// Example of reading from the config file (if it exists)
if (File.Exists(configFilePath))
{
string[] lines = File.ReadAllLines(configFilePath);
Console.WriteLine("Contents of appsettings.json:");
foreach (string line in lines)
{
Console.WriteLine(line);
}
}
else
{
Console.WriteLine("appsettings.json not found in the application directory.");
}
}
catch (Exception ex)
{
Console.WriteLine($"An error occurred: {ex.Message}");
}
}
}
