实现自定义的VsSingleFileGenerator
         用过VS.NET的朋友应该会发现,在编辑一些文件时VS会在文件下面自动创建它的附属文件.而这些附属文件往往是根据设计文件生成的代码文件来的.对于我们想实现这样的功能怎办呢?其实MS早就为我们想好了,只要简单地实现IVsSingleFileGenerator;说是简单不过还是要做些功夫的,就是把编写后VsSingleFileGenerator注册到共公程序集中,然后在注册表里添加一些东西才行.下面介绍自己实现NClay实体设计的SingleFileGenerator,有需要的朋友可以参考代码实现自己的SingleFileGenerator:)

实现目的编写XML模型描述后自动生成附属C#代码文件.

XML设计文件:

<?xml version="1.0" encoding="utf-8" ?>

<nclay_models xmlns="http://nclay.cn/model.xsd" namespace="Blogs.Entities">

  <class name="User" table="TUser" comment="">

    <id name="UserID" type="System.String"/>

    <property name="UserName" type="System.String"/>

    <property name="UserPWD" type="System.String"/>

    <property name="EMail" type="System.String"/>

    <property name="Enabled" type="System.String"/>

    <property name ="Remark" type="System.String"/>

  </class>

</nclay_models>

生成代码模型文件内容:

using System;
    using System.Data;
    using NClay.Data;
    using NClay.Data.Mappings;
    
    
    [TableMapper(Name="User")]
    public partial class User {
        
        private void mUserID;
        
        [PrimaryKey(Name="UserID")]
        public virtual void UserID {
            get {
                return this.mUserID;
            }
            set {
                this.mUserID = value;
            }
        }
        
        public partial class Mapper : Table {
            
            private ObjectField mAll;
            
            private ObjectField mUserID;
            
            public Mapper() : 
                    base("User") {
                this.mAll = new ObjectField("*", this);
                this.mUserID = new ObjectField("UserID", this);
            }
            
            public virtual ObjectField All {
                get {
                    return this.mAll;
                }
            }
            
            public virtual ObjectField UserID {
                get {
                    return this.mUserID;
                }
            }
        }
    }
    
    public partial class ModelContext {
        
        static User.Mapper mUser = new User.Mapper();
        
        public static User.Mapper User {
            get {
                return mUser;
            }
        }
    }

对于SingleFileGenerator的编写我直接就贴代码,其实也没什么好讲就一个类.

using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using Microsoft.VisualStudio.Shell.Interop;
using System.ComponentModel;
using System.CodeDom.Compiler;
using Microsoft.VisualStudio.Shell;
using VSOLE = Microsoft.VisualStudio.OLE.Interop;
using System.CodeDom;
using System.IO;
using System.Xml;

namespace NClay.Generators
{
  

    [Guid("2F6150C6-BC48-4733-96FE-91F2A90AADCF")]
    public class ModelGenerator : IVsSingleFileGenerator, VSOLE::IObjectWithSite
    {
        private CodeDomProvider codeProvider;

        private string codeFileNameSpace;
        private string codeFilePath;

        private object site;

        private IVsGeneratorProgress codeGeneratorProgress;

        public CodeDomProvider CodeProvider
        {
            get
            {
                if (this.codeProvider == null)
                {
                    codeProvider = CodeDomProvider.CreateProvider("C#");
                }

                return this.codeProvider;
            }

            set
            {
                if (value == null)
                {
                    throw new ArgumentNullException();
                }

                this.codeProvider = value;
            }
        }
