I want the program to check if it's installed on the computer (using Clickonce) or just being run (e.g. by Visual Studio).

EDIT: Not a duplicate of How to detect that C# Windows Forms code is executed within Visual Studio? . "e.g." means for example.

回答1:

You can use the ApplicationDeployment.IsNetworkDeployed property. Please note that this only works with ClickOnce installations.

private void CheckApplicationStatus() {
    if (ApplicationDeployment.IsNetworkDeployed) {
        // Do something that needs doing when the application is installed using ClickOnce.
    } else {
        // Do something that needs doing when the application is run from VS.
    }
}
