行号未在错误语句中正确显示 [英] line number not showing correctly in error statement

问题描述

Dim st As StackTrace = New StackTrace(ex, True)
Dim sf As StackFrame = st.GetFrame(st.FrameCount - 1)
Console.WriteLine( sf.GetFileLineNumber())

我在捕获中使用了上面的代码行来显示错误发生时的行号，它显示的是行号，但不是导致错误的行的确切行号.任何想法请帮助

I used the above line of codes in the catch to show the line number when the error happens.Its showing a line number but its not exact line number of the line that cause the error. Any ideas please help

推荐答案

不要做这些奇怪的事情.只需使用Console.WriteLine(ex.StackTrace).

Don''t do such weird things. Just use a Console.WriteLine(ex.StackTrace).

如果您谈论的是Release版本，则行号毫无意义，因为优化可能会重新编写您的代码.

解决此问题的唯一方法是编译并使用该应用程序的Debug版本，但不建议这样做.

If you''re talking about a Release build, line numbers are meaningless as optimizations may have re-written your code.

The only way around this is to compile and use a Debug version of the app, which is not recommended by the way.
