1. 精通T4脚本要从读懂脚本的关键代码片段开始

 1.1. 给类添加注释-->看懂类对应的代码：<#=codeStringGenerator.EntityClassOpening(entity)#>

替换前
WriteHeader(codeStringGenerator, fileManager);
XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
<#=codeStringGenerator.EntityClassOpening(entity)#>
替换后

WriteHeader(codeStringGenerator, fileManager);

string summary=string.Empty;
foreach (var entity in typeMapper.GetItemsToGenerate<EntityType>(itemCollection))
{
fileManager.StartNewFile(entity.Name + ".cs");
BeginNamespace(code);
if(entity.Documentation !=null && entity.Documentation.Summary!=null)
summary=entity.Documentation.Summary;
else
summary=entity.Name;
#>
<#=codeStringGenerator.UsingDirectives(inHeader: false)#>
/// <summary>
/// <#=summary#>
/// </summary>
<#=codeStringGenerator.EntityClassOpening(entity)#>

  1.2. 给命名空间添加注释-->看懂引用的命名空间对应的代码：<#=codeStringGenerator.UsingDirectives(inHeader: false)#>

该方法实现与于odeStringGenerator类下边。代码如下：

  public string UsingDirectives(bool inHeader, bool includeCollections = true){return inHeader == string.IsNullOrEmpty(_code.VsNamespaceSuggestion())? string.Format(CultureInfo.InvariantCulture,"{0}using System;{1}" +"{2}"+"{3}",inHeader ? Environment.NewLine : "",includeCollections ? (Environment.NewLine + "using System.Collections.Generic;") : "",includeCollections ? (Environment.NewLine + "using System.Data;") : "",inHeader ? "" : Environment.NewLine): "";}

 1.3. 给属性添加注释-->看懂属性的代码对应的代码：<#=codeStringGenerator.Property(edmProperty)#>

替换前：

        foreach (var edmProperty in simpleProperties){
#><#=codeStringGenerator.Property(edmProperty)#>

替换后：

foreach (var edmProperty in simpleProperties){
if (edmProperty.Documentation != null && edmProperty.Documentation.Summary != null){summary=edmProperty.Documentation.Summary;}else{summary="";}
#>
/// <summary>/// <#=summary#>/// </summary><#=codeStringGenerator.Property(edmProperty)#>

 1.4. 看懂命名空间namespace对应的代码：namespace <#=code.EscapeNamespace(codeNamespace)#>
