Question

How to Free RAM at Silverlight/WPF ? I define a UserControl MyUC that has a Image and three Textblock. I add 10000 MyUCs to a Grid, then clear the Grid s Children,but RAM is not Freed! Why? MyUC:

<Grid x:Name="LayoutRoot" Background="White">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="32"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>
    <Image Grid.Column="0" Source="{Binding ICO}" Width="32" Height="32"/>
    <StackPanel Grid.Column="1" Orientation="Vertical" Width="359" Margin="0,0,-189,0">
        <TextBlock Text="{Binding ID}"/>
        <TextBlock Text="{Binding Name}"/>
        <TextBlock Text="{Binding URL}"/>
    </StackPanel>
</Grid>

法典:

MyUC uc = null;
for (int i = 0; i < 10000; i++)
{
  uc = new MyUC();
  this.LayoutRoot.Children.Clear();
  this.LayoutRoot.Children.Add(uc);
}

帮助我? 3KS!

很短的答复是,如果你提供的话,你没有明确表示要释放记忆。

由于贵重物品类别的每一例都不属于范围,因此,垃圾收集器将确定不再能够使用。在下一次停车场收集时,将标出无法兑现的事例,记忆将紧凑。它对如何做到这一点至关重要。 NET在发挥作用。

您的测验记忆的诊断是否正在发现垃圾收集的影响是另一个例子,你没有提供关于你使用的诊断信息。

Garbage collection in the Microsoft .NET common language runtime environment completely absolves the developer from tracking memory usage and knowing when to free memory. However, you ll want to understand how it works. Part 1 of this two-part article on .NET garbage collection
