Let your code output the file name, row number, and column number of the exception.

CodeAs follows:

 
Try{// Your code here}Catch(ExceptionEx ){Console. Writeline (ex. Message); system. diagnostics.StacktraceTrace =NewSystem. diagnostics.Stacktrace(EX,True);Console. Writeline (trace. getframe (trace. framecount-1). getmethod (). Name );Console. Writeline (trace. getframe (trace. framecount-1). getfilelinenumber ());Console. Writeline (trace. getframe (trace. framecount-1). getfilecolumnnumber ());}
 

 

A little simpler, you can use exception. tostring ().

Example output of ex. tostring:

System. invalidcastexception: Unable to cast object of Type 'Microsoft. Sharepoint. splist' to type 'Microsoft. Sharepoint. spdocumentlibrary '.
At getfolderlength. program. Main (string [] ARGs) in E: \ code \ CSHARP \ project1 \ Program. CS: line 110

 

The result of system. appdomain. currentdomain. basedirectory. tostring () is as follows:

E: \ code \ CSHARP \ project1 \ bin \ debug \
