範例

以下範例示範如何使用 PickFileResult 類別取得所選檔案的檔案路徑：

using Microsoft.Windows.Storage.Pickers;

var picker = new FileOpenPicker();
var result = await picker.PickSingleFileAsync();
if (result != null)
{
    // Perform this conversion if you have business logic that uses StorageFile
    var storageFile = await Windows.Storage.StorageFile.GetFileFromPathAsync(result.Path)
    // Continue your business logic with storageFile
}
else
{
    // Add error handling logic here
}

#include <winrt/Microsoft.Windows.Storage.Pickers.h>
using namespace winrt::Microsoft::Windows::Storage::Pickers;

FileOpenPicker picker;
auto& result{ co_await openPicker.PickSingleFileAsync() };
if (result)
{
    // Perform this conversion if you have business logic that uses StorageFile
    auto& storageFile{ co_await winrt::Windows::Storage::StorageFile::GetFileFromPathAsync(result.Path) }
    // Continue your business logic with storageFile
}
else
{
    // Add error handling logic here
}

備註

PickFileResult 物件可以轉換成 Windows。透過 GetFileFromPathAsync 使用檔案路徑來取得 Storage.StorageFile 物件。
