Using proportions with c#

How can you use a proportional system so that the scroll feature would not be based on a specific x and y coordinate on the phone screen. I need my program to be able to function across devices regardless of screen size. I am using C#.

Thank you

Look through the 'scroll' actions in TouchActions:

## Automating mobile gestures

While the Selenium WebDriver spec has support for certain kinds of mobile
interaction, its parameters are not always easily mappable to the functionality
that the underlying device automation (like UIAutomation in the case of iOS)
provides. To that end, Appium implements the new TouchAction / MultiAction API
defined in the newest version of the spec
([https://dvcs.w3.org/hg/webdriver/raw-file/tip/webdriver-spec.html#multiactions-1](https://dvcs.w3.org/hg/webdriver/raw-file/tip/webdriver-spec.html#multiactions-1)).
Note that this is different from the earlier version of the TouchAction API in
the original JSON Wire Protocol.

These APIs allow you to build up arbitrary gestures with multiple actuators.
Please see the Appium client docs for your language in order to find examples
of using this API.

Scrolling 'down' for example should work regardless of screen size:

// c#
Dictionary<string, string> scrollObject = new Dictionary<string, string>();
scrollObject.Add("direction", "down");
((IJavaScriptExecutor)driver).ExecuteScript("mobile: scroll", scrollObject));

It says string is not a function

I have no idea what you are talking about.

The C# code is not working for me

Im getting the following error at the IJavaScriptExecutor:

An unhandled exception of type 'System.NotImplementedException' occurred in WebDriver.dll
