.net開發體系里，大部分本地化的實現都是用資源文件實現(.resx)，asp.net core中的多語Culture是指區域性的對象，而UICulture?該對象表示資源管理器在運行時查找區域性特定資源時所用的當前用戶接口區域性。

asp.net core實現也是通過添注入本地化服務，和添加中間件來實現的，例如下：

using Microsoft.Extensions.Localization;var builder = WebApplication.CreateBuilder(args); //添加本地化中間件，Resources builder.Services.AddLocalization(options => options.ResourcesPath = "Resources");var app = builder.Build(); //應用三種本地化資源 var supportedCultures = new[] { "zh-CN", "ja-JP", "en-US" }; var localizationOptions = new RequestLocalizationOptions().SetDefaultCulture(supportedCultures[0]).AddSupportedCultures(supportedCultures).AddSupportedUICultures(supportedCultures); localizationOptions.ApplyCurrentCultureToResponseHeaders = true; app.UseRequestLocalization(localizationOptions); //通過向服務容器中獲取StringLocalizer來獲取具體本地化數據 app.MapGet("/demo",?(IStringLocalizer<SharedResource>?sharedLocalizer)?=> {return sharedLocalizer["ok"].Value; });app.Run(); //ShareResource類型，不需要實現 public class SharedResource { }

.resx文件xml數據，分描述部分和數據部分

<?xml version="1.0" encoding="utf-8"?> <root><!-- Microsoft ResX Schema Version 2.0The primary goals of this format is to allow a simple XML format that is mostly human readable. The generation and parsing of the various data types are done through the TypeConverter classes associated with the data types.Example:... ado.net/XML headers & schema ...<resheader name="resmimetype">text/microsoft-resx</resheader><resheader name="version">2.0</resheader><resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader><resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader><data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data><data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data><data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64"><value>[base64 mime encoded serialized .NET Framework object]</value></data><data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64"><value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value><comment>This is a comment</comment></data>There are any number of "resheader" rows that contain simple name/value pairs.Each data row contains a name, and value. The row also contains a type or mimetype. Type corresponds to a .NET class that support text/value conversion through the TypeConverter architecture. Classes that don't support this are serialized and stored with the mimetype set.The mimetype is used for serialized objects, and tells the ResXResourceReader how to depersist the object. This is currently not extensible. For a given mimetype the value must be set accordingly:Note - application/x-microsoft.net.object.binary.base64 is the format that the ResXResourceWriter will generate, however the reader can read any of the formats listed below.mimetype: application/x-microsoft.net.object.binary.base64value : The object must be serialized with : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter: and then encoded with base64 encoding.mimetype: application/x-microsoft.net.object.soap.base64value : The object must be serialized with : System.Runtime.Serialization.Formatters.Soap.SoapFormatter: and then encoded with base64 encoding.mimetype: application/x-microsoft.net.object.bytearray.base64value : The object must be serialized into a byte array : using a System.ComponentModel.TypeConverter: and then encoded with base64 encoding.--><xsd:schema id="root" xmlns="" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"><xsd:import namespace="http://www.w3.org/XML/1998/namespace" /><xsd:element name="root" msdata:IsDataSet="true"><xsd:complexType><xsd:choice maxOccurs="unbounded"><xsd:element name="metadata"><xsd:complexType><xsd:sequence><xsd:element name="value" type="xsd:string" minOccurs="0" /></xsd:sequence><xsd:attribute name="name" use="required" type="xsd:string" /><xsd:attribute name="type" type="xsd:string" /><xsd:attribute name="mimetype" type="xsd:string" /><xsd:attribute ref="xml:space" /></xsd:complexType></xsd:element><xsd:element name="assembly"><xsd:complexType><xsd:attribute name="alias" type="xsd:string" /><xsd:attribute name="name" type="xsd:string" /></xsd:complexType></xsd:element><xsd:element name="data"><xsd:complexType><xsd:sequence><xsd:element name="value" type="xsd:string" minOccurs="0" msdata:Ordinal="1" /><xsd:element name="comment" type="xsd:string" minOccurs="0" msdata:Ordinal="2" /></xsd:sequence><xsd:attribute name="name" type="xsd:string" use="required" msdata:Ordinal="1" /><xsd:attribute name="type" type="xsd:string" msdata:Ordinal="3" /><xsd:attribute name="mimetype" type="xsd:string" msdata:Ordinal="4" /><xsd:attribute ref="xml:space" /></xsd:complexType></xsd:element><xsd:element name="resheader"><xsd:complexType><xsd:sequence><xsd:element name="value" type="xsd:string" minOccurs="0" msdata:Ordinal="1" /></xsd:sequence><xsd:attribute name="name" type="xsd:string" use="required" /></xsd:complexType></xsd:element></xsd:choice></xsd:complexType></xsd:element></xsd:schema><resheader name="resmimetype"><value>text/microsoft-resx</value></resheader><resheader name="version"><value>2.0</value></resheader><resheader name="reader"><value>System.Resources.ResXResourceReader, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value></resheader><resheader name="writer"><value>System.Resources.ResXResourceWriter, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value></resheader><data name="cancel" xml:space="preserve"><value>Cancel</value></data><data name="no" xml:space="preserve"><value>No</value></data><data name="ok" xml:space="preserve"><value>Yes</value></data> </root>
