Run Time Error - at System.RuntimeMethodHandle.InvokeMethod
-
I am getting an error when running an SSIS ETL, converting aN Excel to CSV. Please assist.
at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)
at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object[] providedArgs, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParams)
at Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript()Csv output is exactly the same as Excel

Step-by-step debugging is what I would suggest.
The absence of evidence is not evidence of absence.

Stan Laurel -
You try to refer to the steps in this article Export SQL Server Table to CSV

I found a code that works:

#region Help: Using Integration Services variables and parameters in a script
/* To use a variable in this script, first ensure that the variable has been added to
* either the list contained in the ReadOnlyVariables property or the list contained in
* the ReadWriteVariables property of this script task, according to whether or not your
* code needs to write to the variable. To add the variable, save this script, close this instance of

* ReadWriteVariables properties in the Script Transformation Editor window.
* To use a parameter in this script, follow the same steps. Parameters are always read-only.
*
* Example of reading from a variable:
* DateTime startTime = (DateTime) Dts.Variables["System::StartTime"].Value;
*
* Example of writing to a variable:
* Dts.Variables["User::myStringVariable"].Value = "new value";

The SSIS is running very long. The data that is being written is not a lot. Have i missed something?
If i modify my Variables to:
, i am getting this error:
Error: '2024' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long.
