public OrCondition (params System.Windows.Automation.Condition[] conditions);

new System.Windows.Automation.OrCondition : System.Windows.Automation.Condition[] -> System.Windows.Automation.OrCondition

Public Sub New (ParamArray conditions As Condition())

参数

conditions

Condition[]

两个或更多的条件，其中的任何一个条件为真则表明发生了匹配。

示例

在以下示例中，一个OrCondition用于检索按钮或单选按钮UI 自动化元素。

/// <summary>
/// Uses OrCondition to retrieve elements that match either of two conditions.
/// </summary>
/// <param name="elementMainWindow">An application window element.</param>
public void OrConditionExample(AutomationElement elementMainWindow)
{
    if (elementMainWindow == null)
    {
        throw new ArgumentException();
    }

    OrCondition conditionButtons = new OrCondition(
        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button),
        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.RadioButton));
    AutomationElementCollection elementCollectionButtons = elementMainWindow.FindAll(
        TreeScope.Subtree, conditionButtons);
    Console.WriteLine("\nButtons and radio buttons:");
    foreach (AutomationElement autoElement in elementCollectionButtons)
    {
        Console.WriteLine(autoElement.Current.Name);
    }

    // Example of getting the conditions from the OrCondition.
    Condition[] conditions = conditionButtons.GetConditions();
    Console.WriteLine("OrCondition has " + conditions.GetLength(0) + " subconditions.");
}
