请问在Metro Style风格的RichEditBox中如何插入图片,我是这么写的
StorageFile file = await Windows.Storage.KnownFolders.DocumentsLibrary.CreateFileAsync("xxx.png", CreationCollisionOption.OpenIfExists);
IRandomAccessStream randomAccessStream = await file.OpenAsync(FileAccessMode.Read);
_editor.Document.GetRange(0, 1).InsertImage(400, 300, 0, Windows.UI.Text.VerticalCharacterAlignment.Baseline, "the image", randomAccessStream);
但是程序没有反应,也没报错
请大虾们帮忙支支招啊
