Application.StartupPath Property

Gets the path for the executable file that started the application, not including the executable name.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public static string StartupPath { get; }

Property Value

Type: System.String
The path for the executable file that started the application.
This path will be different depending on whether the Windows Forms application is deployed using ClickOnce. ClickOnce applications are stored in a per-user application cache in the C:\Documents and Settings\username directory. For more information, see Accessing Local and Remote Data in ClickOnce Applications.

The following code example gets this property and displays its value in a text box. The example requires that textBox1 has been placed on a form.

private void PrintStartupPath() {
    textBox1.Text = "The path for the executable file that " +
       "started the application is: " +
       Application.StartupPath;
 }
