'dotnet build' 指定主要方法

问题描述

我正在使用 dotnet 从命令行构建 .NET Core C# 项目.该项目有多个带有 main 方法的类.因此我得到错误:

I am using dotnet to build a .NET Core C# project from the command line. The project has multiple classes with a main method. Thus I get the error:

$ dotnet build
Microsoft (R) Build Engine version 15.1.548.43366
Copyright (C) Microsoft Corporation. All rights reserved.

Test.cs(18,28): error CS0017: Program has more than one entry point defined. Compile with /main to specify the type that contains the entry point.

Build FAILED.

传递 /main 开关导致错误:

Passing the /main switch results in the error:

$ dotnet build /main:Test
Microsoft (R) Build Engine version 15.1.548.43366
Copyright (C) Microsoft Corporation. All rights reserved.

MSBUILD : error MSB1001: Unknown switch.
Switch: /main:Test

如何将 /main 开关传递给 dotnet 命令?

How can I pass the /main switch to the dotnet command?

推荐答案

您可以编辑您的 csproj 以定义要使用的类(在 PropertyGroup 内):

You can edit your csproj to define which class to use (inside a PropertyGroup):

<StartupObject>foo.Program2</StartupObject>

或通过以下方式在命令行上指定此 MSBuild 属性:

or specify this MSBuild property on the command line via:

$ dotnet build foo.csproj -p:StartupObject=foo.Program2

哪里

namespace foo
{
  class Program2{ public static void Main() {} }
}
