在使用Entity Framework過程中，有時需要借助工具生成Code First的代碼，而Entity Framework Reverse POCO Code First Generator是一款不錯的工具

在Visual Studio中，通過“工具”→“擴展和更新...”來安裝Entity Framework Reverse POCO Code First Generator

這裏添加一個控制臺項目，並在項目中添加POCO Code First Generator 生成模板

默認的生成模板如下：

    // Please make changes to the settings below.
    // All you have to do is save this file, and the output file(s) is/are generated. Compiling does not regenerate the file(s).

    // Elements to generate ***************************************************************************************************************

    // Use these namespaces to specify where the different elements now live. These may even be in different assemblies.
    // Please note this does not create the files in these locations, it only adds a using statement to say where they are.
    // The way to do this is to add the "EntityFramework Reverse POCO Code First Generator" into each of these folders.
    // Then set the .tt to only generate the relevant section you need by setting
    //      ElementsToGenerate = Elements.Poco; in your Entity folder,
    //      ElementsToGenerate = Elements.Context | Elements.UnitOfWork; in your Context folder,

    PrependSchemaName = true;   // Control if the schema name is prepended to the table name

    // Table Suffix ***********************************************************************************************************************

    //     If TableSuffix is "Entity" then Order will be OrderEntity

    // Filtering **************************************************************************************************************************
    // Use the following table/view name regex filters to include or exclude tables/views
    // Exclude filters are checked first and tables matching filters are removed.
    //  * If left null, none are excluded.
    //  * If not null, any tables matching the regex are excluded.
    // Include filters are checked second.
    //  * If left null, all are included.
    //  * If not null, only the tables matching the regex are included.
    // For clarity: if you want to include all the customer tables, but not the customer billing tables.
    //      TableFilterInclude = new Regex("^[Cc]ustomer.*"); // This includes all the customer and customer billing tables
    //      TableFilterExclude = new Regex(".*[Bb]illing.*"); // This excludes all the billing tables
    //
    // Example:     TableFilterExclude = new Regex(".*auto.*");

    // Regex are used first to filter the list down, then this function is run last.
    // Return true to include the table, return false to exclude it.
    TableFilter = (Table t) =>
    {
        // Example: Exclude any table in dbo schema with "order" in its name.
        //if(t.Schema.Equals("dbo", StringComparison.InvariantCultureIgnoreCase) && t.NameHumanCase.ToLowerInvariant().Contains("order"))
        //    return false;

    // Table renaming *********************************************************************************************************************
    // Use the following function to rename tables such as tblOrders to Orders, Shipments_AB to Shipments, etc.
    // Example:
    TableRename = (string name, string schema, bool isView) =>
    {
        // Example
        //if (name.StartsWith("tbl"))
        //    name = name.Remove(0, 3);
        //name = name.Replace("_AB", "");

        //if(isView)
        //    name = name + "View";

        // If you turn pascal casing off (UsePascalCase = false), and use the pluralisation service, and some of your
        // tables names are all UPPERCASE, some words ending in IES such as CATEGORIES get singularised as CATEGORy.
        // Therefore you can make them lowercase by using the following
        // return Inflector.MakeLowerIfAllCaps(name);

        // If you are using the pluralisation service and you want to rename a table, make sure you rename the table to the plural form.
        // For example, if the table is called Treez (with a z), and your pluralisation entry is
        //     new CustomPluralizationEntry("Tree", "Trees")
        // Use this TableRename function to rename Treez to the plural (not singular) form, Trees:
        // if (name == "Treez") return "Trees";

        return name;

    // Column modification*****************************************************************************************************************

    //EnumsDefinitions.Add(new EnumDefinition { Schema = "dbo", Table = "OrderHeader", Column = "OrderStatus", EnumType = "OrderStatusType" }); // This will replace OrderHeader.OrderStatus type to be an OrderStatusType enum

    // Use the following function if you need to apply additional modifications to a column
    // eg. normalise names etc.
    UpdateColumn = (Column column, Table table) =>

在App.config中添加數據庫連接字符串，如果是Web項目，則是Web.config，這裏name與POCO 模板指定的Name一致（可以修改模板或配置文件，隨便一處，保持一致就行）

在模板中Ctrl + S，這時提示運行模板，點擊“確定”

這是生成的代碼：
