描述Description

dotnet 命令有两个函数:The dotnet command has two functions:

  • 它提供了用于处理 .NET Core 项目的命令。It provides commands for working with .NET Core projects.

    例如,dotnet build 生成项目。For example, dotnet build builds a project. 每个命令定义自己的选项和参数。Each command defines its own options and arguments. 所有命令都支持 --help 选项,用于打印有关如何使用命令的简短文档。All commands support the --help option for printing out brief documentation about how to use the command.

  • 它运行 .NET Core 应用程序。It runs .NET Core applications.

    指定应用程序 .dll 文件的路径以运行应用程序。You specify the path to an application .dll file to run the application. 运行应用程序即意味着找到并执行入口点,对于控制台应用,入口点是 Main 方法。To run the application means to find and execute the entry point, which in the case of console apps is the Main method. 例如,dotnet myapp.dll 运行 myapp 应用程序。For example, dotnet myapp.dll runs the myapp application. 要了解部署选项,请参阅 .NET Core 应用程序部署See .NET Core application deployment to learn about deployment options.

选项Options

dotnet 本身有不同的选项,可用于运行命令和运行应用程序。Different options are available for dotnet by itself, for running a command, and for running an application.

dotnet 本身的选项Options for dotnet by itself

以下是 dotnet 本身的选项。The following options are for dotnet by itself. 例如 dotnet --infoFor example, dotnet --info. 这些选项打印出有关环境的信息。They print out information about the environment.

  • --info

    打印出有关 .NET Core 安装和计算机环境(如当前操作系统)的详细信息,并提交 .NET Core 版本的 SHA。Prints out detailed information about a .NET Core installation and the machine environment, such as the current operating system, and commit SHA of the .NET Core version.

  • --version

    打印使用中的 .NET Core SDK 版本。Prints out the version of the .NET Core SDK in use.

  • --list-runtimes

    打印已安装的 .NET Core 运行时的列表。Prints out a list of the installed .NET Core runtimes. x86 版本的 SDK 只列出 x86 运行时,而 x64 版本的 SDK 只列出 x64 运行时。An x86 version of the SDK lists only x86 runtimes, and an x64 version of the SDK lists only x64 runtimes.

  • --list-sdks

    打印已安装的 .NET Core SDK 的列表。Prints out a list of the installed .NET Core SDKs.

  • -h|--help

    打印可用命令列表。Prints out a list of available commands.

用于运行命令的 SDK 选项SDK options for running a command

以下选项适用于使用命令的 dotnetThe following options are for dotnet with a command. 例如 dotnet build --helpFor example, dotnet build --help.

  • -d|--diagnostics

    启用诊断输出。Enables diagnostic output.

  • -v|--verbosity <LEVEL>

    设置命令的详细级别。Sets the verbosity level of the command. 允许使用的值为 q[uiet]m[inimal]n[ormal]d[etailed]diag[nostic]Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic]. 并非在每个命令中均受支持。Not supported in every command. 请参阅特定的命令页,确定此选项是否可用。See specific command page to determine if this option is available.

  • -h|--help

    打印出给定命令的文档,如 dotnet build --helpPrints out documentation for a given command, such as dotnet build --help.

  • command options

    每个命令定义特定于该命令的选项。Each command defines options specific to that command. 有关可用选项的列表,请参阅特定命令页。See specific command page for a list of available options.

运行时选项Runtime options

dotnet 运行应用程序时,可以使用以下选项。The following options are available when dotnet runs an application. 例如 dotnet myapp.dll --roll-forward MajorFor example, dotnet myapp.dll --roll-forward Major.

  • --additionalprobingpath <PATH>

    包含要进行探测的探测策略和程序集的路径。Path containing probing policy and assemblies to probe.

  • --additional-deps <PATH>

    附加 .deps.json 文件的路径。Path to an additional .deps.json file. deps.json 文件包含依赖项、编译依赖项和用于解决程序集冲突的版本信息列表。A deps.json file contains a list of dependencies, compilation dependencies, and version information used to address assembly conflicts. 有关详细信息,请参阅 GitHub 上的运行时配置文件For more information, see Runtime Configuration Files on GitHub.

  • --depsfile <PATH_TO_DEPSFILE>

    deps.json 文件的路径。Path to the deps.json file. .deps.json 文件是一个配置文件,其中包含有关运行应用程序所需的依赖项的信息。A deps.json file is a configuration file that contains information about dependencies necessary to run the application. 此文件由 .NET Core SDK 生成。This file is generated by the .NET Core SDK.

  • --runtimeconfig

    runtimeconfig.template.json 文件的路径。Path to a runtimeconfig.json file. runtimeconfig.template.json 文件是包含运行时设置的配置文件。A runtimeconfig.json file is a configuration file that contains run-time settings. 有关详细信息,请参阅 .NET Core 运行时配置设置For more information, see .NET Core run-time configuration settings.

  • --roll-forward <SETTING> 自 .NET Core SDK 3.0 起可用 。--roll-forward <SETTING> Available starting with .NET Core SDK 3.0.

    控制将前滚操作应用于应用的方式。Controls how roll forward is applied to the app. SETTING 可以为下列值之一。The SETTING can be one of the following values. 如果未指定,则 Minor 为默认类型。If not specified, Minor is the default.

    • LatestPatch - 前滚到最高补丁版本。LatestPatch - Roll forward to the highest patch version. 这会禁用次要版本前滚。This disables minor version roll forward.
    • Minor - 如果缺少所请求的次要版本,则前滚到最低的较高次要版本。Minor - Roll forward to the lowest higher minor version, if requested minor version is missing. 如果存在所请求的次要版本,则使用 LatestPatch 策略。If the requested minor version is present, then the LatestPatch policy is used.
    • Major - 如果缺少所请求的主要版本,则前滚到最低的较高主要版本和最低的次要版本。Major - Roll forward to lowest higher major version, and lowest minor version, if requested major version is missing. 如果存在所请求的主要版本,则使用 Minor 策略。If the requested major version is present, then the Minor policy is used.
    • LatestMinor - 即使存在所请求的次要版本,仍前滚到最高次要版本。LatestMinor - Roll forward to highest minor version, even if requested minor version is present. 适用于组件托管方案。Intended for component hosting scenarios.
    • LatestMajor - 即使存在所请求的主要版本,仍前滚到最高主要版本和最高次要版本。LatestMajor - Roll forward to highest major and highest minor version, even if requested major is present. 适用于组件托管方案。Intended for component hosting scenarios.
    • Disable - 不前滚。Disable - Don't roll forward. 仅绑定到指定的版本。Only bind to specified version. 建议不要将此策略用于一般用途,因为它会禁用前滚到最新补丁的功能。This policy isn't recommended for general use because it disables the ability to roll forward to the latest patches. 该值仅建议用于测试。This value is only recommended for testing.

    Disable 外,所有设置都将使用可用的最高补丁版本。With the exception of Disable, all settings will use the highest available patch version.

    前滚行为还可以在项目文件属性、运行时配置文件属性和环境变量中进行配置。Roll forward behavior can also be configured in a project file property, a run-time configuration file property, and an environment variable. 有关详细信息,请参阅主版本运行时前滚For more information, see Major-version runtime roll forward.

  • --roll-forward-on-no-candidate-fx <N> 在 .NET Core 2.x SDK 中可用 。--roll-forward-on-no-candidate-fx <N> Available in .NET Core 2.x SDK.

    所需的共享框架不可用时,请定义行为。Defines behavior when the required shared framework is not available. N 可以是:N can be:

    • 0 - 禁用次要版本前滚。0 - Disable even minor version roll forward.
    • 1 - 前滚次要版本,但不前滚主版本。1 - Roll forward on minor version, but not on major version. 这是默认行为。This is the default behavior.
    • 2 - 前滚次要和主版本。2 - Roll forward on minor and major versions.

    有关详细信息,请参阅前滚For more information, see Roll forward.

    从 .NET Core 3.0 开始,此选项被 --roll-forward 取代,应改为使用此取代项。Starting with .NET Core 3.0, this option is superseded by --roll-forward, and that option should be used instead.

  • --fx-version <VERSION>

    用于运行应用程序的 .NET Core 运行时版本。Version of the .NET Core runtime to use to run the application.

    此选项将重写应用程序 .runtimeconfig.json 文件中第一个框架引用的版本。This option overrides the version of the first framework reference in the application's .runtimeconfig.json file. 这意味着,仅当只有一个框架引用时,它才会按预期方式工作。This means it only works as expected if there's just one framework reference. 如果应用程序具有多个框架引用,则使用此选项可能会导致错误。If the application has more than one framework reference, using this option may cause errors.
