>我正在尝试在WPF中使用WIN10 api来对用户进行身份验证。
我正在使用Microsoft文档的示例代码：
private async System.Threading.Tasks.Task<string> RequestConsent(string userMessage)
{
string returnMessage;
if (String.IsNullOrEmpty(userMessage))
{
userMessage = "Please provide fingerprint verification.";
}
try
{
// Request the logged on user's consent via fingerprint swipe.
var consentResult = await Windows.Security.Credentials.UI.UserConsentVerifier.RequestVerificationAsync(userMessage);
switch (consentResult)
{
case Windows.Security.Credentials.UI.UserConsentVerificationResult.Verified:
returnMessage = "Fingerprint verified.";
break;
case Windows.Security.Credentials.UI.UserConsentVerificationResult.DeviceBusy:
returnMessage = "Biometric device is busy.";
break;
case Windows.Security.Credentials.UI.UserConsentVerificationResult.DeviceNotPresent:
returnMessage = "No biometric device found.";
break;
case Windows.Security.Credentials.UI.UserConsentVerificationResult.DisabledByPolicy:
returnMessage = "Biometric verification is disabled by policy.";
break;
case Windows.Security.Credentials.UI.UserConsentVerificationResult.NotConfiguredForUser:
returnMessage = "The user has no fingerprints registered. Please add a fingerprint to the " +
"fingerprint database and try again.";
break;
case Windows.Security.Credentials.UI.UserConsentVerificationResult.RetriesExhausted:
returnMessage = "There have been too many failed attempts. Fingerprint authentication canceled.";
break;
case Windows.Security.Credentials.UI.UserConsentVerificationResult.Canceled:
returnMessage = "Fingerprint authentication canceled.";
break;
default:
returnMessage = "Fingerprint authentication is currently unavailable.";
break;
}
}
catch (Exception ex)
{
returnMessage = "Fingerprint authentication failed: " + ex.ToString();
}
return returnMessage;
}
CheckAvailabilityAsync()工作正常。RequestVerificationAsync()调用 api 并显示模式对话框，但在身份验证后，模式对话框消失，应用程序仍在等待结果...
还尝试构建应用程序并以管理员身份运行它，但仍然没有结果。
我错过了什么？
在方法调用中尝试这个，它对我有用
var res = RequestConsent("Please provide fingerprint verification.").Result;
