EF架構~為EF DbContext產生的實體添加註釋

void WriteProperty(CodeGenerationTools code, EdmProperty edmProperty){    if (edmProperty.Documentation != null && edmProperty.Documentation.Summary != null)    {         WriteProperty(Accessibility.ForProperty(edmProperty),                      code.Escape(edmProperty.Documentation.Summary),                      code.Escape(edmProperty.TypeUsage),                      code.Escape(edmProperty),                      code.SpaceAfter(Accessibility.ForGetter(edmProperty)),                      code.SpaceAfter(Accessibility.ForSetter(edmProperty)));    }    else    {        WriteProperty(Accessibility.ForProperty(edmProperty),                      code.Escape(edmProperty.Name),                      code.Escape(edmProperty.TypeUsage),                      code.Escape(edmProperty),                      code.SpaceAfter(Accessibility.ForGetter(edmProperty)),                      code.SpaceAfter(Accessibility.ForSetter(edmProperty)));    }}void WriteNavigationProperty(CodeGenerationTools code, NavigationProperty navigationProperty){    var endType = code.Escape(navigationProperty.ToEndMember.GetEntityType()); if (navigationProperty.Documentation != null && navigationProperty.Documentation.Summary != null)    {     WriteProperty(PropertyVirtualModifier(Accessibility.ForProperty(navigationProperty)),                  code.Escape(navigationProperty.Documentation.Summary),                  navigationProperty.ToEndMember.RelationshipMultiplicity == RelationshipMultiplicity.Many ? ("ICollection<" + endType + ">") : endType,                  code.Escape(navigationProperty),                  code.SpaceAfter(Accessibility.ForGetter(navigationProperty)),                  code.SpaceAfter(Accessibility.ForSetter(navigationProperty)));    }    else    {      WriteProperty(PropertyVirtualModifier(Accessibility.ForProperty(navigationProperty)),                  code.Escape(navigationProperty.Name),                  navigationProperty.ToEndMember.RelationshipMultiplicity == RelationshipMultiplicity.Many ? ("ICollection<" + endType + ">") : endType,                  code.Escape(navigationProperty),                  code.SpaceAfter(Accessibility.ForGetter(navigationProperty)),                  code.SpaceAfter(Accessibility.ForSetter(navigationProperty)));    }}void WriteProperty(string accessibility, string summary, string type, string name, string getterAccessibility, string setterAccessibility){#>    /// <summary>    /// <#=summary#>    /// </summary>    <#=accessibility#> <#=type#> <#=name#> { <#=getterAccessibility#>get; <#=setterAccessibility#>set; }<#+}

　儲存後，它會將結果輸出到與TT檔案同時的cs檔案中，如果模板出現錯誤，也會將錯誤資訊輸出到CS檔案中，如果成功，就會有如何內容：

//------------------------------------------------------------------------------ // <auto-generated> //    This code was generated from a template. // //    Manual changes to this file may cause unexpected behavior in your application. //    Manual changes to this file will be overwritten if the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------  using System; using System.Collections.Generic;

　　

　

使用EF架構時，你的實體產生方案有多種，entity object,poco,dbcontext等等，對於entity object方案產生的實體，我們感覺很臃腫，當然它的功能很強在，但有時在查看類實體時，有些麻煩，因為所有實體都在一個類檔案中，有點像linq to sql，而它的類格局也與dbml有些雷同，當然這不是今天的重點，今天主要說的是當EDMX檔案添加註釋後，如何把注釋同時添加到dbcontext實體上。

方案：修改dbcontext的T4模版

實現：找到以下代碼塊

先為類加註釋

string summary=string.Empty;foreach (var entity in ItemCollection.GetItems<EntityType>().OrderBy(e => e.Name)){    fileManager.StartNewFile(entity.Name + ".cs");    BeginNamespace(namespaceName, code);    if(entity.Documentation !=null && entity.Documentation.Summary!=null)       summary=entity.Documentation.Summary;     else        summary=entity.Name; #>/// <summary>/// <#=summary#>/// </summary>

　　

再為類中的屬性加註釋

void WriteProperty(CodeGenerationTools code, EdmProperty edmProperty) {}

將原來的代碼刪除，替換成如下代碼
