在vb.net中检查外部依赖关系 [英] Checking for external dependances in vb.net

问题描述

我以前从未真正做过什么，但是什么是确保我的应用程序使用的任何外部程序集/dll可用以及正确版本的最佳方法是什么.

Something i've never really done before, but what is the best way to make sure that any external assemblies/dll's that my application uses are available, and possibly the correct version.

我写了一个依赖于System.Data.SQLite.dll的应用程序，我去了缺少dll的计算机上对其进行测试，而我的应用程序由于该dll丢失而抛出了运行时异常.我该如何捕获此错误?

I wrote an app that relies on the System.Data.SQLite.dll, i went to test it on a machine where that dll was missing, and my app just threw up a runtime exception because the dll was missing. How can i trap this error?

推荐答案

您要做的是使用反射检查并查看程序集是否可以加载到内存中.将其包装在try..catch块中，并处理由此而来的任何特定异常.

What you want to do is use reflection to check and see if the assembly can be loaded into memory. Wrap that up in a try..catch block and handle any of the specific exceptions that come from it.

Try
    Assembly.Load("System.Data.SQLite, Version=1.0.22.0, Culture=neutral, PublicKeyToken=DB937BC2D44FF139");
Catch ex As FileNotFoundException
    //do something here
End Try
