BooleanSwitch.Enabled 属性

public:
 property bool Enabled { bool get(); void set(bool value); };

public bool Enabled { get; set; }

member this.Enabled : bool with get, set

Public Property Enabled As Boolean

属性值

true 如果启用开关，则为否则，为 false. 默认值为 false。

例外

示例

下面的代码示例创建一个 BooleanSwitch 并使用开关来确定是否打印错误消息。 该开关在类级别创建。 该方法 Main 将错误的位置传递给该位置 MyMethod，该位置将输出错误消息和发生错误的位置。

//Class level declaration.
/* Create a BooleanSwitch for data.*/
static BooleanSwitch dataSwitch = new BooleanSwitch("Data", "DataAccess module");

static public void MyMethod(string location)
{
    //Insert code here to handle processing.
    if (dataSwitch.Enabled)
        Console.WriteLine("Error happened at " + location);
}

public static void Main(string[] args)
{
    //Run the method that writes an error message specifying the location of the error.
    MyMethod("in Main");
}

'Class level declaration.
' Create a BooleanSwitch for data. 
Private Shared dataSwitch As New BooleanSwitch("Data", "DataAccess module")


Public Shared Sub MyMethod(location As String)
    'Insert code here to handle processing.
    If dataSwitch.Enabled Then
        Console.WriteLine(("Error happened at " + location))
    End If
End Sub

'Entry point which delegates to C-style main Private Function
Public Overloads Shared Sub Main()
    Main(System.Environment.GetCommandLineArgs())
End Sub
 
Overloads Public Shared Sub Main(args() As String)
    'Run the method that writes an error message specifying the location of the error.
    MyMethod("in Main")
End Sub

注解

默认情况下，此字段设置为 false “已禁用”。 若要启用开关，请为此字段分配值 true。 若要禁用开关，请将值赋给 false。 此属性的值由基类属性 SwitchSetting的值确定。
