InvokePattern用于可被调用的控件，如按钮。Used to support controls that do not maintain state when activated but rather initiate or perform a single, unambiguous action, such as a button.

封装如下代码：

public static InvokePattern GetInvokePattern(AutomationElement element)

{

object currentPattern = null;

if (!element.TryGetCurrentPattern(InvokePattern.Pattern, out currentPattern))

{

Log.Error(string.Format("Element with AutomationId '{0}' and Name '{1}' does not support the InvokePattern.",

element.Current.AutomationId, element.Current.Name));

throw new Exception(string.Format("Element with AutomationId '{0}' and Name '{1}' does not support the InvokePattern.",

element.Current.AutomationId, element.Current.Name));

}

return currentPattern as InvokePattern;

}

//Get the button element

AutomationElement button = AutomationElementSearch.FindElementById(window, "button1");

Assert.IsNotNull(button);

Thread.Sleep(1000);

//Click the button

InvokePattern invokepattern = Invokepattern.GetInvokePattern(button);

Assert.IsNotNull(invokepattern);

invokepattern.Invoke();

Thread.Sleep(1000);
