在VB.Net中传递函数指针

本文介绍了在VB.Net中传递函数指针的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 来自C / C ++背景，我如何将函数指针传递给 函数？我想编写一个处理某些线程产生的函数。 这就是我想要的东西： 函数（thesub as< ; functionptr？>） dim t as new system.threading.thread（_ new system.threading.threadstart（Addressof thesub）） .... 如何在VB.Net中获得类似内容？ 解决方案 使用委托。代表相当于.NET中的函数指针。 问候， Ron " ChrisB" <章**** @ discussions.microsoft.com>在消息中写道 news：87 ********************************** @ microsof t.com ... 来自C / C ++背景，我如何将函数指针传递给函数？我想写一个处理某些线程产生的函数。这就是我想要的东西： 函数（thesub as< functionptr？>） new system.threading.threadstart（Addressof thesub）） 我怎么能得到这样的东西进入VB.Net？ " Ron Bremmers" < R ******** @ home.nl>。 schrieb：使用委托。委托相当于.NET中的函数指针。 文档： Visual Basic语言概念 - 事件和代表 < URL：http：//msdn.microsoft.com/library/en-us/vbcn7/html/vaconEventsDelegatesInheritance.asp> - MS Herfried K.

WagnerM V P <URL:http://dotnet.mvps.org/>V B <URL:http://dotnet.mvps.org/dotnet/faqs/> I tried using delegates but I don''t know how. I tried something like this:delegate function fpMyfunc()(I also tried delegate sub fpMyfunc())Then:function( thesub as fpMyfunc )dim t as new system.threading.thread( _new system.threading.threadstart( Addressof thesub ))But this did not work. VB.Net complained about the "thesub" after theAddressof.. saying that I do not need ()''s after the sub name, as if it didnot recognize "thesub" as being a subroutine."Ron Bremmers" wrote: Use delegates.
