我有一个winform程序,现在我需要增强与UWP应用程序的功能通信,所以我添加了参考Windows.DLL并对winform程序做了一些更改,现在我可以通过方法 Launcher.LaunchUriAsync调用UWP应用程序(),但方法上的任何异常 Launcher.LaunchUriForResultsAsync(),
你可以给我一些建议吗?提前谢谢。异常: 操作标识符无效。 (HRESULT异常:0x800710DD)
部分代码:
// The protocol handled by the launched app
Uri testAppUri = new Uri("etrace.scanner:");
var supportStatus = await Launcher.QueryUriSupportAsync(testAppUri, LaunchQuerySupportType.Uri, "80a2fbc7-843e-46ca-a740-cbb1bc604d33_y890260wv9vv0");
if (supportStatus != LaunchQuerySupportStatus.Available)
{
// Check the app available or not.
}
var inputData = new ValueSet();
inputData["TestData"] = "Test data";
var optionsE = new LauncherOptions { TargetApplicationPackageFamilyName = "80a2fbc7-843e-46ca-a740-cbb1bc604d33_y890260wv9vv0" };
// Call APP successully.
bool success = await Launcher.LaunchUriAsync(testAppUri, optionsE, inputData);
Debug.WriteLine(success);
// Got an exception:
var result = await Launcher.LaunchUriForResultsAsync(testAppUri, optionsE, inputData);

您可以使用AppServiceConnections。

它们用于UWP与其他应用程序的通信,它们在Win32中受支持并且可以相同地工作。
