Exception can be used to check for exception and inner exception for Win32Exception-derived exception.
catch (exception e) var w32ex E = as a Win32 exception; if (w32ex == null) w32ex E = .InnerException as Win32Exception; if (w32ex! = zero) integer = w32ex.ErrorCode; // create a product // do other information
Starting in C # 6, if can be used in a catch fact to specify a condition that must appear true for a handler to throw a single exception.
catch (Win32Exception ex) where (e.g. InnerException win32Exception) var w32ex = (Win32Exception) ex.InnerException; program code var = w32ex.ErrorCode;
As in the comments, you really need to see which exception is actually thrown in order tounderstanding exactly what you can do and under what circumstances a particular catch is better than catching one exception. About us:
You should look at the members of the thrown exception, in particular .Message and .InnerException .
I would also like to see the documentation for InvokeMethod to see if it is throwing a more specific exception class than an exception – simply because of the win32Exception suggested by @Preet. Maybe you shouldn’t take the base class in Exception and just watch it.

Based on Preet Sangha’s solution, the following should accurately cover the scenario where you are working with a large solution that can lead to many internal exceptions.
Try
Object means the result of processClass.InvokeMethod ("Create", methodArgs); grab E) (Exception // Here I was hoping to get a great error code. anytime (ExceptionContainsErrorCode (e, 10004)) // Perform the desired actions
private bool ExceptionContainsErrorCode (exception e, int ErrorCode) Win32Exception winEx means e for Win32Exception; if possible (winEx! = null && ErrorCode == winEx.ErrorCode) returns true; while (e.InnerException! = null) ExceptionContainsErrorCode (e return.InnerException, ErrorCode); false return;
I’m not going to go too deep into the need to travel in order to evaluate and implementbest practices for exception handling by limiting each expected exception type to its silent blocks.

I recommend that you use Clean Message from the exception object like in the following code
Try
Object Result = processClass.InvokeMethod ("Create", methodArgs);capture (exception e) // Use Console.Write (e.Message); from a console application // and use MessageBox.Show (e.Message); using WindowsForm app and WPF

Another method is to get the error code of each exception class directly. For example:
catch (exception) (for example if.InnerException is ServiceResponseException) ServiceResponseException srex = ex.InnerException as ServiceResponseException; ErrorCode group = srex.ErrorCode.ToString ();
Fire a signal, stop the input block, and use the debugger to make the exception visually appealing and see what facts you have. -Alternatively, you can get the code without debugging and throw the type of exception using GetType ().
It is easy to use an exception. ToString () they return There is a line after the description of the difference. You can also check the debug database of the software package as it contains debug information / more or less logs the whole application.
Syntax errors occur during design time when you create type errors in your code. For example, if you write completely as you write, when you write WHILE in that case, you will run into a syntax error because C # is a case-sensitive language.
