问题描述

所以我想现在如果可能的.NET语言来忽略错误,而不使用try抓建设?

So I want to now if that possible for .NET languages to ignore error without using try catch construction ?

我可以忽略与#nowarring 40例​​如交战,我可以忽略错误?

I can ignore warring with #nowarring 40 for example, can I ignore error ?

为什么我需要它?

只是想叫这个路系统暂停

simply wanted to call system pause with this way

open System.Runtime.InteropServices
[<DllImport(@"msvcrt.dll")>]
extern void system(string str)
system "pause"

但得到错误信息

but got Error message

不平衡的堆栈。这可能是  因为托管的PInvoke签名  不匹配的非托管目​​标  签名。确保通话  会议及参数  的PInvoke签名与目标  非托管签名。

所以,我不在乎,它的工作原理。但是,我可以忽略这个错误?没有做怪异的东西,这样的:

So I don't care, it works. But can I just ignore this error ? without doing weird stuff like that :

try (system "pause") catch |_->()

好吧,我解决我的问题,加入CallingConvention = CallingConvention.Cdecl,但问题是关于跳过异常是什么,所以我还是不知道,如果我能做到这一点。

Ok , I solved my problem by adding CallingConvention=CallingConvention.Cdecl, but what the question was about skipping exceptions, so and I still don't know if I can do it.

所以,也许我要告诉一些真正的理由不被向下投硬 - 有时它的事项的程序与硬错误的职业,甚至住,但即使有时你并不需要赶上他们。你只需要忽略他们...

So maybe I need to tell some real reason to not be down-voted hard - sometimes it's matters for program to live even with hard errors occupations, but even sometimes you don't need to catch them. You need just ignore them...

题外话:关于使用INT的空白,而不是证明图像:

off topic : proof image about using void instead of int :

推荐答案

  • 在C#中,我不认为有办法忽略所有的异常,除了的try ... catch
  • 在VB.Net有一个办法忽略所有异常:

VB.Net code:

VB.Net code:

On Error Resume Next '' all exceptions after this point will be ignored  
System("pause")

不过,这是一个危险的功能。例外规定,只有在被忽略

But it's a dangerous feature. Exceptions should only be ignored if

  1. 您绝对有信心,你知道他们为什么发生
  2. 您绝对有信心可以安全地忽略它们。

在我的愚见,并没有冒犯的意思,从你的问题,我不认为你明白为什么发生错误或者为什么它是危险的忽略它。

In my humble opinion, and with no offence meant, from your question I don't think you understand why the error has occurred or why it is dangerous to ignore it.
