＆＃39; System.Data.SqlServerCe.RepairOption＆＃39;不包含＆＃39; RecoverAllPossibleRows＆＃39;的定义

Question

我正在使用nant构建一个Windows应用程序，当运行rebuild命令来清理当前构建并创建新的程序集文件时，我在命令提示符中收到以下错误：

这是LxSqlCeOprn.cs的一部分，其中包含第85行，其中发生错误：

using System.Data.SqlServerCe;
public static void RepairDb (string fileSpec, bool delCorruptRows)
        {
            RepairOption opt = delCorruptRows ? RepairOption.DeleteCorruptedRows : RepairOption.RecoverAllPossibleRows;
            //System.Data.SqlServerCe.RepairOption opt = new System.Data.SqlServerCe.RepairOption();
            //opt = delCorruptRows ? RepairOption.DeleteCorruptedRows : RepairOption.RecoverAllPossibleRows;


            try
            {
                LxNformTools.StopService ();
                char[] delimiter = {'.'};
                string[] temp = fileSpec.Split(delimiter);
                string fileBackup = temp[0] + "tempBak." + temp[1];
                File.Copy(fileSpec, fileBackup, true);
                SqlCeEngine engine = GetEngine (fileBackup);
                LxSystemLogger.Log ("Repairing SQL CE database: " +
                                    engine.LocalConnectionString +
                                    "RepairOption=" + opt,
                                    LxSeverity.Info, "LxSqlCeOprn.RepairDb");
                //Attmpt to repair file only if Verify fails
                if(!engine.Verify(VerifyOption.Enhanced))
                {
                    engine.Repair (null, opt);
                    if(engine.Verify(VerifyOption.Enhanced))
                    {
                        File.Copy(fileBackup, fileSpec, true);
                    }
                }
                File.Delete(fileBackup);
                LxSystemLogger.Log ("Repair complete.",
                                    LxSeverity.Success, "LxSqlCeOprn.RepairDb");
            }
            catch (Exception e)
            {
                LxSystemLogger.Log ("Error in database operation", e,
                                    "LxSqlCeOprn.RepairDb");
                if (LxBaseException.IsCriticalException(e))  throw;
            }
            return;
        } // end RepairDb

我正在使用visual studio professional 2013，对System.Data.SqlServerCe.dll的引用已添加到项目中，Visual Studio不会抱怨任何缺少的定义。我认为这可能与环境设置有关，任何提示都将受到赞赏。
