在尝试构建我的 VB.NET 项目时,我遇到了项目级条件编译常量错误。它写道:

project-level conditional compilation constant 'VB_VER=9.0,TARGET="exe",CONFIG="Debug",_MyType="Console",PLATFORM="AnyCPU",DEBUG;^^ ^^ TRACE' not valid: Character is not valid.

我最近将它升级到最新版本(从2.0),我感觉这与它有关。

这是什么意思?我无知...

这是我的项目文件:

最佳答案

我更改了此块中的 DefineConstants 标记:

 <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
<OutputPath>bin\Debug\</OutputPath>
<DocumentationFile>svchost.xml</DocumentationFile>
<AllowUnsafeBlocks>true</AllowUnsafeBlocks>
<DefineConstants>DEBUG;TRACE</DefineConstants>
<DebugSymbols>true</DebugSymbols>
<NoStdLib>false</NoStdLib>
<Optimize>false</Optimize>
<WarningLevel>4</WarningLevel>
<NoWarn>42016,42017,42018,42019,42032</NoWarn>
<DebugType>full</DebugType>
</PropertyGroup>


<DefineConstants>DEBUG</DefineConstants>

它就像一个魅力!
