AddEnvironmentVariables(IConfigurationBuilder, String)

來源:

EnvironmentVariablesExtensions.cs

新增 IConfigurationProvider 一個能讀取環境變數設定值的指定前綴。

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

參數

configurationBuilder

IConfigurationBuilder

IConfigurationBuilder要補充的。

prefix

String

環境變數名稱必須以前綴開頭。 前綴會從環境變數名稱中移除。 前綴會被轉換DefaultTransformation後，再與轉換後的環境變數名稱匹配，因此應在預轉換形式中指定（例如Logging__）。Logging:

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

來源:

EnvironmentVariablesExtensions.cs

新增一個 IConfigurationProvider 能讀取環境變數設定值，並以指定的前綴和變數名稱轉換。

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

參數

configurationBuilder

IConfigurationBuilder

IConfigurationBuilder要補充的。

prefix

String

環境變數名稱必須以前綴開頭。 前綴會從環境變數名稱中移除。 前綴會被 variableNameTransformation 轉換後，再與轉換後的環境變數名稱匹配，因此應在預轉換表單中指定。

variableNameTransformation

Func<String,String>

一個可以轉換環境變數名稱的函式。 設定後，這會完全取代預設行為。 當 null使用 時 DefaultTransformation 。
