How to Set the Working Directory for External Processes Launched from .NET?

Controlling the Working Directory of .NET-Launched Processes

When initiating external applications from your .NET application, defining the execution directory is frequently essential. This is particularly important if the external application relies on files residing within its working directory.

The ProcessStartInfo class in .NET offers a WorkingDirectory property for this purpose. Setting this property allows you to precisely specify the directory from which the process should begin and locate necessary files.

For instance, consider launching a Java application from C# that depends on supporting files located in its own directory. The following code demonstrates how to achieve this:

using System.Diagnostics;

var startInfo = new ProcessStartInfo();
startInfo.WorkingDirectory = Directory.GetCurrentDirectory();
// Configure other necessary properties

Process proc = Process.Start(startInfo);

This code snippet ensures the Java application starts with the current directory as its working directory, providing access to required supporting files.

Utilizing the WorkingDirectory property offers a straightforward method to define the default directory for any launched process, guaranteeing a suitable environment for successful execution.
