如何使用Where語句執行UpdateAsync

Question

我有一個包含1行的表。日誌=> 1 | flagLog => 0

public async void updateFlag() 
    { 
     var local = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "hinos.sqlite"); 
     SQLiteAsyncConnection con = new SQLiteAsyncConnection(local, SQLiteOpenFlags.Create | SQLiteOpenFlags.ReadWrite); 

     var updateFlagLog = await con.FindAsync<logon>(u => u.log == 1); 
     if (updateFlagLog != null) 
     { 
      await con.UpdateAsync(?????); 
     // update logon set flagLog = 1 where log = 1; 

     } 
    } 

我行與此COMAND

var updateFlagLog = await con.FindAsync<logon>(u => u.log == 1); 

但我不知道如何使用更新此行。

我相信你只需要傳遞你想要更新的對象。

var updateFlagLog = await con.FindAsync<logon>(u => u.log == 1); 
    if (updateFlagLog != null) 
    { 
     // TODO do the changes you need to updateFlagLog 

     // Update the object 
     await con.UpdateAsync(updateFlagLog); 
    }
