uno-platform - 如何将文件选择器与 WASM 集成？

Question

我想从我的电脑上传一张图片并在网格视图中显示它。

如何从我的 PC 中选择图像并在 WASM 中列出它们？

Answer 1

Uno 3.6中添加了对此的官方支持。您可以使用FilePicker API在任何平台上选择文件和文件夹。

var picker = new Windows.Storage.Pickers.FileOpenPicker();

var file = await picker.PickSingleFileAsync();
if (file != null)
{
    // Application now has read/write access to the picked file
    this.textBlock.Text = "Picked photo: " + file.Name;
}
else
{
    this.textBlock.Text = "Operation cancelled.";
}
