AddEnvironmentVariables(IConfigurationBuilder)

Source:

EnvironmentVariablesExtensions.cs

添加一个 IConfigurationProvider 从环境变量中读取配置值。

public:
[System::Runtime::CompilerServices::Extension]
 static Microsoft::Extensions::Configuration::IConfigurationBuilder ^ AddEnvironmentVariables(Microsoft::Extensions::Configuration::IConfigurationBuilder ^ configurationBuilder);

public static Microsoft.Extensions.Configuration.IConfigurationBuilder AddEnvironmentVariables(this Microsoft.Extensions.Configuration.IConfigurationBuilder configurationBuilder);

static member AddEnvironmentVariables : Microsoft.Extensions.Configuration.IConfigurationBuilder -> Microsoft.Extensions.Configuration.IConfigurationBuilder

<Extension()>
Public Function AddEnvironmentVariables (configurationBuilder As IConfigurationBuilder) As IConfigurationBuilder

参数

configurationBuilder

IConfigurationBuilder

要添加到的 IConfigurationBuilder 。

返回

IConfigurationBuilder

。IConfigurationBuilder

AddEnvironmentVariables(IConfigurationBuilder, Action<EnvironmentVariablesConfigurationSource>)

Source:

EnvironmentVariablesExtensions.cs

添加一个 IConfigurationProvider 从环境变量中读取配置值。

public:
[System::Runtime::CompilerServices::Extension]
 static Microsoft::Extensions::Configuration::IConfigurationBuilder ^ AddEnvironmentVariables(Microsoft::Extensions::Configuration::IConfigurationBuilder ^ builder, Action<Microsoft::Extensions::Configuration::EnvironmentVariables::EnvironmentVariablesConfigurationSource ^> ^ configureSource);

public static Microsoft.Extensions.Configuration.IConfigurationBuilder AddEnvironmentVariables(this Microsoft.Extensions.Configuration.IConfigurationBuilder builder, Action<Microsoft.Extensions.Configuration.EnvironmentVariables.EnvironmentVariablesConfigurationSource>? configureSource);

static member AddEnvironmentVariables : Microsoft.Extensions.Configuration.IConfigurationBuilder * Action<Microsoft.Extensions.Configuration.EnvironmentVariables.EnvironmentVariablesConfigurationSource> -> Microsoft.Extensions.Configuration.IConfigurationBuilder

<Extension()>
Public Function AddEnvironmentVariables (builder As IConfigurationBuilder, configureSource As Action(Of EnvironmentVariablesConfigurationSource)) As IConfigurationBuilder

参数

builder

IConfigurationBuilder

要添加到的 IConfigurationBuilder 。

configureSource

Action<EnvironmentVariablesConfigurationSource>

配置源的操作。

返回

IConfigurationBuilder

。IConfigurationBuilder

AddEnvironmentVariables(IConfigurationBuilder, String)

Source:

EnvironmentVariablesExtensions.cs

添加一个 IConfigurationProvider 从具有指定前缀的环境变量读取配置值。

public:
[System::Runtime::CompilerServices::Extension]
 static Microsoft::Extensions::Configuration::IConfigurationBuilder ^ AddEnvironmentVariables(Microsoft::Extensions::Configuration::IConfigurationBuilder ^ configurationBuilder, System::String ^ prefix);

public static Microsoft.Extensions.Configuration.IConfigurationBuilder AddEnvironmentVariables(this Microsoft.Extensions.Configuration.IConfigurationBuilder configurationBuilder, string? prefix);

static member AddEnvironmentVariables : Microsoft.Extensions.Configuration.IConfigurationBuilder * string -> Microsoft.Extensions.Configuration.IConfigurationBuilder

<Extension()>
Public Function AddEnvironmentVariables (configurationBuilder As IConfigurationBuilder, prefix As String) As IConfigurationBuilder

参数

configurationBuilder

IConfigurationBuilder

要添加到的 IConfigurationBuilder 。

prefix

String

环境变量名称必须以其开头的前缀。 前缀将从环境变量名称中删除。 前缀由转换后 DefaultTransformation 根据转换后的环境变量名称进行匹配，因此应在预转换形式（例如 Logging__ ，例如 Logging:）中指定该前缀。

返回

IConfigurationBuilder

。IConfigurationBuilder

AddEnvironmentVariables(IConfigurationBuilder, String, Func<String,String>)

Source:

EnvironmentVariablesExtensions.cs

添加一个 IConfigurationProvider 从具有指定前缀和变量名称转换的环境变量读取配置值。

public:
[System::Runtime::CompilerServices::Extension]
 static Microsoft::Extensions::Configuration::IConfigurationBuilder ^ AddEnvironmentVariables(Microsoft::Extensions::Configuration::IConfigurationBuilder ^ configurationBuilder, System::String ^ prefix, Func<System::String ^, System::String ^> ^ variableNameTransformation);

public static Microsoft.Extensions.Configuration.IConfigurationBuilder AddEnvironmentVariables(this Microsoft.Extensions.Configuration.IConfigurationBuilder configurationBuilder, string? prefix, Func<string,string>? variableNameTransformation);

static member AddEnvironmentVariables : Microsoft.Extensions.Configuration.IConfigurationBuilder * string * Func<string, string> -> Microsoft.Extensions.Configuration.IConfigurationBuilder

<Extension()>
Public Function AddEnvironmentVariables (configurationBuilder As IConfigurationBuilder, prefix As String, variableNameTransformation As Func(Of String, String)) As IConfigurationBuilder

参数

configurationBuilder

IConfigurationBuilder

要添加到的 IConfigurationBuilder 。

prefix

String

环境变量名称必须以其开头的前缀。 前缀将从环境变量名称中删除。 前缀由转换后 variableNameTransformation 根据转换后的环境变量名称进行匹配，因此应在预转换形式中指定该前缀。

variableNameTransformation

Func<String,String>

转换环境变量名称的函数。 设置后，这将完全替换默认行为。 null使用时DefaultTransformation。

返回

IConfigurationBuilder

。IConfigurationBuilder
