问题
I made a windows service application that I want to create a setup file. When User request application via our website url with query parameters, (Eg: http://test.com/setup.exe?id=1212) I need to change the current app.config key value to that query parameter value.
I also need to update this application automatically when new release is ready. So ClickOnce or squirrel for windows might be an option but as I couldn't find way to achieve above task.
Following questions are bit similar but don't solve this problem: * How can we retrieve query string information in a ClickOnce Application? * ClickOnce: How do I pass a querystring value to my app *through the installer*?
How can I achieve this?
回答1:
1. First, enable the query string parameters to be passed to the application.
2. Access the query string like this
private NameValueCollection GetQueryString()
{
if (ApplicationDeployment.IsNetworkDeployed)
{
try
{
string rawQueryString = String.Empty;
rawQueryString = ApplicationDeployment.CurrentDeployment.ActivationUri.Query;
NameValueCollection queryString;
try
{
queryString = HttpUtility.ParseQueryString(ApplicationDeployment.CurrentDeployment.ActivationUri.Query);
}
catch (Exception ex)
{
throw new Exception("Unauthorized access!");
}
return queryString;
}
catch (Exception ex)
{
if (ApplicationDeployment.CurrentDeployment == null)
{
throw new Exception("Deployment error");
}
else if (ApplicationDeployment.CurrentDeployment.ActivationUri == null)
{
throw new Exception("Unable to read data");
}
else
{
throw new Exception("Error with deployment: " + ex.Message);
}
}
}
else
{
throw new Exception("This application may not be accessed directly");
}
}
3. Update the app.config
App.Config change value
