c# - ListView/列表过滤器Windows Phone 8.1 C#

我有数据清单

public class PopImage
{
    public async Task<List<PopImage>> PopDatas()
    {
        string imgfolder = "PopularImages";
        var data = new List<PopImage>();
        StorageFolder folder = Windows.ApplicationModel.Package.Current.InstalledLocation;
        StorageFolder subfolder = await folder.GetFolderAsync(imgfolder);

        var files = await subfolder.GetFilesAsync();
        foreach (var items in files)
        {
            data.Add(new PopImage(imgfolder+"/"+items.DisplayName+ ".jpg", items.DisplayName));
        }

        return data;
    }

    public PopImage(string imagePath, string imageName)
    {
        ImagePath = imagePath;
        ImageName = imageName;
    }

    public string ImagePath { get; set; }
    public string ImageName { get; set; }
}

我想添加一个文本框并对其进行过滤（如果文本框已更改），
我需要申请什么？

最佳答案

您需要将TextChanged事件添加到TextBox中。
首先在您的XAML中添加以下内容：

<TextBox Name="tbListFilter" TextChanged="tbListFilter_TextChanged"/>

那么后面的代码是：

private void tbListFilter_TextChanged(object sender, TextChangedEventArgs e)
{
     yourFilteredList = yourPopImageList.Where(p => p.ImageName.ToUpper().Contains(tbListFilter.Text.ToUpper())).ToList();
}
