範例

在下列範例中， TablePattern 會從 AutomationElement 取得控制項模式。

///--------------------------------------------------------------------
/// <summary>
/// Obtains a TablePattern control pattern from an 
/// automation element.
/// </summary>
/// <param name="targetControl">
/// The automation element of interest.
/// </param>
/// <returns>
/// A TablePattern object.
/// </returns>
///--------------------------------------------------------------------
private TablePattern GetTablePattern(
    AutomationElement targetControl)
{
    TablePattern tablePattern = null;

    try
    {
        tablePattern =
            targetControl.GetCurrentPattern(
            TablePattern.Pattern)
            as TablePattern;
    }
    // Object doesn't support the 
    // GridPattern control pattern
    catch (InvalidOperationException)
    {
        return null;
    }

    return tablePattern;
}

備註

消費者介面自動化用戶端應用程式會使用此識別碼。 消費者介面自動化提供者應該使用 中的 TablePatternIdentifiers 對等欄位。

模式識別碼會傳遞至方法，例如從 GetCurrentPattern 指定的 AutomationElement 擷取感興趣的控制項模式。
