陷阱错误并继续卡车运输

我编写了一个 c# 监视程序来检查数据库中的值。它运行 4 个单独的检查，然后输出结果 （Winform）。

一切都运行良好，然后上周第一次检查遇到了问题，整个程序停止了。

所以我的问题是我将如何在 4 项检查中的任何一项中捕获任何错误并继续前进/卡车运输？

我可以通过尝试捕获来做到这一点，或者这会停止程序吗？

代码示例

        bool bTestDate;
        object LastDataDate;
      //--  Check A - Table 1
        OdbcConnection DbConnection = new OdbcConnection("DSN=EDATA");
        try
        {
            DbConnection.Open();
        }
        catch (OdbcException ex)
        {
            Console.WriteLine("connection to the DSN '" + connStr + "' failed.");
            Console.WriteLine(ex.Message);
            return;
        }
        OdbcCommand DbCommand = DbConnection.CreateCommand();
        DbCommand.CommandText = "SELECT NAME, UNAME, DATIME_ENDED FROM XPF WHERE NAME='XXXX'";
        OdbcDataReader DbReader = DbCommand.ExecuteReader();
        int fCount = DbReader.FieldCount;
        string myBatch;
        string myUser;
        string myDate;
        while (DbReader.Read())
        {
            Console.Write(":");
            myBatch = DbReader.GetString(0);
            myUser = DbReader.GetString(1);
            myDate = DbReader.GetString(2);
            myDate = myDate.Remove(myDate.Length - 10);
            for (int i = 0; i < fCount; i++)
            {
                String col = DbReader.GetString(i);
                Console.Write(col + ":");
            }
            tbxxx.Text = string.Format("{0:dd/M/yy   H:mm:ss}", myDate);
            bool TestDate;
            TestDate = CheckDate(Convert.ToDateTime(myDate));
            CheckVerif(TestDate, lblVerifixxx);
        }
      //--  Check B - Table 2
        string cnStr = setConnectionString();
        string mySQL = "Select Max(TO_DATE(TIME_ID, 'DD/MM/YYYY')) FROM table";
        OracleConnection cn = new OracleConnection(cnStr);
        cn.Open();
        OracleCommand cmd = new OracleCommand(mySQL, cn);
        LastDataDate = cmd.ExecuteScalar();
        cmd.Dispose();
        tbLastDate.Text = string.Format("{0:dd MMM yy}", LastDataDate);
        bTestDate = CheckDate(Convert.ToDateTime(LastDataDate));
        CheckVerif(bTestDate, lblVerif);
      //--  Check C - Table 3
        mySQL = "Select Max(xxx_DATE) from AGENT";
        OracleCommand cmd2 = new OracleCommand(mySQL, cn);
        LastDataDate = cmd2.ExecuteScalar();
        cmd2.Dispose();
        tbxxx2.Text = string.Format("{0:dd MMM yy}", LastDataDate);
        bool TestDatex;
        TestDatex = CheckDate(Convert.ToDateTime(LastDataDate));
        CheckVerif(TestDatex, lblVerif2);

try
{
    string s = null;
    ProcessString(s);
}
// Most specific:
catch (ArgumentNullException e)
{
    Console.WriteLine("{0} First exception caught.", e);
}
// Least specific:
catch (Exception e)
{
    Console.WriteLine("{0} Second exception caught.", e);
