How do you set up a file association with a click-once application?

问题

I have a click-once application.

I have an associated file that I store the application's data in.

When a user clicks on one of these files I want it to open the click-once app and load the file.

I can set up the file association in the publish, the icon and name is correctly set. Clicking on the file opens the application, but the application doesn't seem to be passed the path to the file - the command arguments are empty.

How do I get it so that the path to the file is passed to the application?

回答1:

When using Click Once, arguments are not passed in on the command line, they are passed in through the Click Once deployment system:

AppDomain.CurrentDomain.SetupInformation.ActivationArguments.ActivationData

For example, in your Program.cs file:

foreach (string commandLineFile in AppDomain.CurrentDomain.SetupInformation.ActivationArguments.ActivationData)
{
    MessageBox.Show( string.Format("Command Line File: {0}", commandLineFile) );
}

Hope this helps.
