CodePudding user response:

I'm VS2015, run the following code, enter the id, name, x and y, sequentially input name of collapse, the pop-up error message

CodePudding user response:

You look the Debug mode order step debugging, something wrong?

CodePudding user response:

There seems to be wrong in the input data, but I don't know what wrong with reason,,,

CodePudding user response:

Single step breakpoint debugging, at least take a look at your first input data, process data has any problem with you
