WP7 Mango：如何刪除實時圖塊？

Question

我正在使用以下代碼在設備上創建實時磁貼：

ShellTile tile = ShellTile.ActiveTiles.FirstOrDefault();
StandardTileData newTileData = new StandardTileData
{
    BackgroundImage = new Uri(string.Format("isostore:{0}", DefaultLiveTilePath), UriKind.Absolute),
    Title = "Test"
};
tile.Update(newTileData);

稍后我想刪除實時圖塊圖像，並在固定時將其恢復為應用程序圖標。 這可能嗎？

Answer 1

根據這篇博客，您可以使用此代碼

public void DeleteExistingTile()  
{  
    var foundTile = ShellTile.ActiveTiles.FirstOrDefault(x => x.NavigationUri.ToString().Contains("DetailId=123"));  

    // If the Tile was found, then delete it.  
    if (foundTile != null)  
    {  
        foundTile.Delete();  
    }  
}  

Answer 2

每次應用程序啟動時，我都會將我的磁貼重置為正常時使用以下代碼：

    private void ResetLiveTileToNormal()
    {
        ShellTile TileToFind = ShellTile.ActiveTiles.FirstOrDefault();


        ShellTileData shellData = new StandardTileData
        {
            Title = "XXXXXXXX",
            Count = 0,
            BackContent = "",
            BackTitle = "",
            BackBackgroundImage = new Uri("", UriKind.Relative),
            BackgroundImage = new Uri(@"/Images/LiveTiles/XXXXXX.png", UriKind.Relative)
        };
        TileToFind.Update(shellData);
    }

Answer 3

ShellTile.ActiveTiles.FirstOrDefault(); 已經過時了。

void clearTile() {

            ShellTileData tileData = new StandardTileData
            {
                Title = "",
                Count = 0,
                BackContent = "",
                BackTitle = "",
                BackBackgroundImage = new Uri("", UriKind.Relative),
                BackgroundImage = new Uri(@"/ApplicationIcon.png", UriKind.Relative)
            };
            IEnumerator<ShellTile> it = ShellTile.ActiveTiles.GetEnumerator();
            it.MoveNext();
            ShellTile tile = it.Current;
            tile.Update(tileData);
        }
