どのように私は

Question

string connString = string.Format("'{0}';Pooling=False;Open Mode=NonExclusiveReadWrite;Password=Galwaypipe001", path); 
DatabaseTarget dbt = new DatabaseTarget(); 
dbt.Name = "NLog Database"; 
dbt.ConnectionString = connString; // connStringBuilder.ConnectionString; // connString; 
dbt.DBProvider = "VistaDB.Provider, VistaDB.5.NET40, Version=5.0.0.0, Culture=neutral"; 

に上記の結果をVistaDB5データベースを使用するようにNLog v4のを設定します：

  VistaDBConnectionStringBuilder connStringBuilder = new VistaDBConnectionStringBuilder(); 
      connStringBuilder.Password = "***"; 
      connStringBuilder.DataSource = pathandFilenameTovdb5DB; 
      connStringBuilder.Pooling = false; 
      connStringBuilder.OpenMode = VistaDB.VistaDBDatabaseOpenMode.NonexclusiveReadWrite; 

      DatabaseTarget dbt = new DatabaseTarget(); 
      dbt.Name = "NLog Database"; 
      dbt.DBProvider = "VistaDB.Provider.VistaDBConnection, VistaDB.5.NET40, Version=5.0.0.0, Culture=neutral, PublicKeyToken=dfc935afe2125461"; 
      dbt.ConnectionString = connStringBuilder.ConnectionString;
