.NET,Android上的PCL(Xamarin)
在极少数的Android设备上,我在此代码中从SQLite收到数据库锁定错误。有没有办法告诉系统“等待”,直到数据库准备好插入? (iOS很好)
private async Task InsertForLanguage(MySystem data, int languageId)
{
await ClearDatabase(languageId);
await _db.InsertAllAsync(data.XXX);
await _db.InsertAllAsync(data.TTT);
await _db.InsertAllAsync(data.RRR);
await _db.InsertAllAsync(data.EEE);
}
private async Task ClearDatabase(int languageId)
{
await _db.ExecuteAsync("delete from XXX where Languageid=?", languageId);
await _db.ExecuteAsync("delete from TTT where Languageid=?", languageId);
await _db.ExecuteAsync("delete from RRR where Languageid=?", languageId);
await _db.ExecuteAsync("delete from EEE where Languageid=?", languageId);
}
答案 0 :(得分:0)
您可以使用try catch将代码置于循环中,当数据库就绪时,您的尝试将成功
