如何在SQL Server 2005和c#应用程序中消除死锁

我有一个c#的windows服务代码，主要负责更新数据库中表中的记录，但我在日志中总是得到很多错误，所有错误都是关于资源死锁，

错误:

System.Data.SqlClient。SqlException (0x80131904): Transaction (Process . 1904ID 57)在锁资源上与另一个进程发生死锁被选为死锁受害者。重新运行事务。在System.Data.SqlClient.SqlConnection。OnError (SqlException异常,布尔breakConnection，动作1 wrapCloseInAction) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj, Boolean callerHasConnectionLock, Boolean asyncClose) at System.Data.SqlClient.TdsParser.TryRun(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj, Boolean& dataReady) at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async, Int32 timeout, Task& task, Boolean asyncWrite) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, TaskCompletionSource完成，Int32超时，任务&的任务,布尔asyncWrite) atSystem.Data.SqlClient.SqlCommand.InternalExecuteNonQuery (TaskCompletionSource"1sendToPipe, Int32超时;布尔asyncWrite) atSystem.Data.SqlClient.SqlCommand.ExecuteNonQuery ()WheelTrackListener.DataAccess.SQLDBA。ExecuteNQuery (SqlCommand cmd,Boolean isShowError, ConnectionStringType, CountryCode, StringdeviceID, Int32 retry, String functionCallName)ClientConnectionId: e45e4cf1-a113-46b7-b9b5-dc5ee8111406

现在，我想问，我可以尝试或检查资源是否被锁定?如果锁定，如何等待更新，直到它被释放?

下面是我当前的代码:

              string NS_Indicator, string Latitude, string EWIndicator,

              string Near_ByLocation, string Near_ByLocation_AR, 
              string Gis_dataID, string address, string ar_adress, string Device_ID)
{
        SQLMethods sql = new SQLMethods();
        SqlCommand cmd = sql.cmdUpdateVehicleLastPosition(UTCDate, UTC_Time, NS_Indicator, Latitude, EWIndicator, Longtitude, Speed, Processed, Near_ByLocation, Near_ByLocation_AR, Gis_dataID, address, ar_adress, Device_ID);
        SQLDBA sqlDBA = new SQLDBA();
        return sqlDBA.ExecuteNQuery(cmd, true, ConnectionStringType.OMN, Device_ID, 10, "updateVehicleLastPosition");
}
