示例

下面的示例演示如何使用 LockElements 属性。The following example shows how to use the LockElements property.

// Show how to use LockElements
// It locks and unlocks the urls element.
static void LockElements()
{

    try
    {
        // Get the configuration file.
        System.Configuration.Configuration config =
            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);

        // Get the MyUrls section.
        UrlsSection myUrlsSection =
            config.GetSection("MyUrls") as UrlsSection;

        if (myUrlsSection == null)
            Console.WriteLine("Failed to load UrlsSection.");
        else
        {
            // Get MyUrls section LockElements collection.
            ConfigurationLockCollection lockElements =
                myUrlsSection.LockElements;

            // Get MyUrls section LockElements collection 
            // enumerator.
            IEnumerator lockElementEnum =
                 lockElements.GetEnumerator();

            // Position the collection index.
            lockElementEnum.MoveNext();

            if (lockElements.Contains("urls"))
                // Remove the lock on the urls element.
                lockElements.Remove("urls");
            else
                // Add the lock on the urls element.
                lockElements.Add("urls");

            // Save the change.
            config.Save(ConfigurationSaveMode.Full);

        }

    }
    catch (ConfigurationErrorsException err)
    {
        Console.WriteLine("[LockElements: {0}]",
            err.ToString());
    }
}

Shared Sub LockElements()

        Else
            ' Get MyUrls section LockElements collection.
            Dim lockElements _
            As ConfigurationLockCollection = _

            ' Get MyUrls section LockElements collection 
            ' enumerator.
            Dim lockElementEnum As IEnumerator = _
            lockElements.GetEnumerator()

            If lockElements.Contains("urls") Then
                ' Remove the lock on the urls element.
                lockElements.Remove("urls")
            Else
                ' Add the lock on the urls element.
                lockElements.Add("urls")
            End If
            ' Save the change.
            config.Save(ConfigurationSaveMode.Full)
        End If

    Catch err As ConfigurationErrorsException
        Console.WriteLine("[LockElements: {0}]", _
        err.ToString())
    End Try

End Sub 'LockElements

注解

LockElements属性让你锁定你指定的所有元素。The LockElements property allows you to lock all the elements you specify.

若要执行此操作,应使用Contains方法下, 一个示例中所述。To do that, you use the Contains method, as explained in the next example.

备注

LockElements属性,可防止子元素向其应用此规则从正在修改的配置元素。The LockElements property allows you to prevent the child configuration elements of the element to which you apply the rule from being modified. 使用LockItem如果你想要将常规锁放在元素本身以及及其子元素。Use LockItem if you want to put a general lock on the element itself and its child elements.
