代码不会超过VS2012的异常

Question

I have a try catch statement and when the code goes to throw the exception, it will not run past this point.

I press F5/F10 and the code keeps running the same line of code.

Is this to do with a setting in VS2012?

Calling code:

       if (!string.IsNullOrEmpty(connections.xmlconSIPPPremium))
                    {
                        try
                        {
                            DataTable dt = GetUtilityFiles(connections.xmlconSIPPPremium);
                            foreach (DataRow dr in dt.Rows)
                            {
                                File.WriteAllBytes(_rootDirectory + @"\" + dr["UtilityName"], (byte[])dr["UtilityBytes"]);
                            }
                        }
                        catch (Exception ex)
                        {
                            MessageBox.Show(ex.Message);
                        }

                    }
                    else if (!string.IsNullOrEmpty(connections.xmlconSSASPremium))
                    {
                        try
                        {
                            DataTable dt = GetUtilityFiles(connections.xmlconSSASPremium);
                            foreach (DataRow dr in dt.Rows)
                            {
                                File.WriteAllBytes(_rootDirectory + @"\" + dr["UtilityName"], (byte[])dr["UtilityBytes"]);
                            }
                        }
                        catch(Exception ex)
                        {
                            MessageBox.Show(ex.Message);
                        }

                    }
                }

Issue:

    private DataTable GetUtilityFiles(string strCon)
    {
        DataTable dt = new DataTable();

        using (SqlConnection con = new SqlConnection(strCon))
        {
            try
            {
                using (SqlCommand cmd = new SqlCommand("[dmm].[vertUtility_Select]", con))
                {
                    SqlDataAdapter sda = new SqlDataAdapter(cmd); 
                    sda.Fill(dt);         
                }
            }
            catch (Exception ex)
            {
                throw;
            }
            return dt;
        }
    }

Thanks!

Answer 1

Is it just that you want to switch off the "exception assistant"?

Tools -> options -> Debugging -> Enable the exception assistant [unchecked]

Then the exceptions won't stop execution.

Hope this helps!

Answer 2

When debugging there is indeed a setting in VS2012 how to you want to handle exceptions. Check under Debug -> Exceptions...

When you have the exception checked as "Thrown" the debugger will stop at that exception. Read more about "First chance exceptions": What is a "first chance exception"?

Read more about Exception handling in VS2012: http://msdn.microsoft.com/query/dev11.query?appId=Dev11IDEF1&l=EN-US&k=k(vs.debug.exceptions);k(TargetFrameworkMoniker-.NETFramework,Version%3Dv4.0);k(DevLang-csharp)&rd=true

Also, when debugging, and you get the Exception assistand dialog, you can uncheck the option to break when that specific exception occurs.
