CodePudding user response:

Use file record first positioning to the error log, occasional mistake toughest,
Write a log, a few lines went wrong after a look at the end of the logging location, position error is below,

CodePudding user response:

Abnormal information record is too little,

You need to record this three,
Ex. The Message
Ex. InnerException. Message
Ex. The StackTrace

We can analysis

CodePudding user response:

You write log to find the law of the error, such as when performing ten times, every tenth certain error, program is dead will regularly, you can put the wrong that you quoted a few times the output parameters of debugged, performed one hundred times normal, behind may perform again have a problem, it may is a problem of parameter
