EnvDTE is a assembly-wrapped COM library containing the objects and members for Visual Studio core automation.

It ' s widely used in Visual Studio Plugins to provide ability manipulate Visual studio functionalities.

By using the EnvDTE inside texttemplate, we can create a easy solution for massive file creation.

Usage

First you need include EnvDTE to Texttemplate

<#@ Assembly Name= "EnvDTE" #><#@ import namespace= "EnvDTE" #>

Also, need to set the hostspecific to «true».

<#@ template debug= "false" hostspecific= "true" language= "C #" #>

This would allow your to use itexttemplateenginehost instance (Host), which allows your to access current Texttemplat e instance.

Then using following code to obtain an instance of EnvDTE.DTE

var host = this. Host; Itexttemplateenginehostvar serviceprovider = (IServiceProvider) host; Convert Host to Iserviceprovidervar DTE = (envdte.dte) serviceprovider.getservice (typeof (EnvDTE.DTE)); Using IServiceProvider to get instance for EnvDTE

Get Current Solution

<summary>///Get Current Solution instance///Http://msdn.microsoft.com/en-us/library/envdte.solution_ Members (v=vs.90). Aspx///</summary>envdte.solution getcurrentsolution (DTE DTE) {return DTE. Solution;}

Get project item of the text template file

<summary>///Get Project Item of this text template file///http://msdn.microsoft.com/en-us/library/ Envdte.projectitem_members (v=vs.90). Aspx///</summary>envdte.projectitem Getprojectitemofthistexttemplate ( DTE DTE) {return DTE. Solution.findprojectitem (this. Host.templatefile);}

Get Current Project

EnvDTE.Project Getcurrentproject (DTE DTE) {return getprojectitemofthistexttemplate (DTE). ContainingProject;}

ADD subitem under Project text template

void Addsubitem (DTE DTE, string path) {var item = getprojectitemofthistexttemplate (DTE);//item. Collection//http://msdn.microsoft.com/fr-fr/library/envdte.projectitems_members (v=vs.90). aspx//Using Add from Template to add Sub item into Text Templateitem.ProjectItems.AddFromTemplate (this. Host.templatefile, path);}

Clear all subitems under the current text template file

void Cleartexttemplategenerateditems (DTE DTE, BOOL Deletediskfile = False) {var item = getprojectitemofthistexttemplate ( DTE);//item. Collection only provides insertion Functions.foreach (ProjectItem subitem in item. ProjectItems) {file.delete (subitem.filenames[1]); Subitem.delete ();}}

Example

Create class file and SQL file from XML file:Models.xml

<?xml version= "1.0" encoding= "Utf-8"? ><models><model name= "MyUser" ><property name= "FirstName" Type= "string" ></property><property name= "LastName" type= "string" ></Property></Model> <model name= "MyGroup" ><property name= "name" type= "string" ></property></model></models >

Create models for this XML structure:

Class Model {public string name {get; private set;} Public Ireadonlylist Properties {get; private set;} Public Model (XmlNode node) {if (node. attributes["name"]!=null) name = node. attributes["Name"]. Value;var properties = new List (); foreach (XmlNode subnode in node. SelectNodes ("property")) {properties. ADD (new Property (subnode));} This.properties = properties;}} Class Property{public string name {get; private set;} public string type {get; private set;} Public Property (XmlNode node) {if (node. attributes["name"]!=null) name = node. attributes["Name"]. Value;if (node. attributes["type"]!=null) type = node. attributes["type"]. Value;} public string Getsqltype () {if (type== "string") return "nvarchar"; return "ERROR:" +type+ "";}}

Using XmlDocument class load XML file:

XmlDocument doc = new XmlDocument ();d OC. Load (this. Host.resolvepath ("Models.xml")); This.cleartexttemplategenerateditems (DTE, TRUE); List models = new list (); foreach (XmlNode node in Doc. SelectNodes ("/models/model")) Models. ADD (New Model (node));

Then generate class file from Models

<summary>///Generate CSharp class files///</summary>void Generateclassfile (DTE DTE, IEnumerable models {foreach (Model m in models) {#>public class <#= m.name #> {<#+ foreach (var p in m.properties) {  #>publ IC <#= p.type #> <#= p.name #> {get; set;} <#+} #>}<#+var FilePath = Host.resolvepath ("") + "\ \" + M.name + ". cs"; Attention, file path must use "\" not "/" using (StreamWriter w = file.createtext (FilePath)) {//write The code generated T o Filew. WriteLine (this. Generationenvironment.tostring ());//empty the code generatedthis. Generationenvironment.remove (0, this. Generationenvironment.length);} ADD Item to Solutionthis.addprojectitem (Dte,filepath);}}

and generate SQL files from Models

<summary>///Generate SQL files///</summary>void generatesqlfile (DTE DTE, IEnumerable models) {foreach ( Model m in models) {#>create TABLE <#= m.name #> (<#+ foreach (var p in m.properties) {  #><#= p.name # > <#= p.getsqltype () #><#+} #>) <#+var FilePath = Host.resolvepath ("") + "\ \" + M.name + ". sql"; Attention, file path must use "\" not "/" using (StreamWriter w = file.createtext (FilePath)) {//write The code generated T o Filew. WriteLine (this. Generationenvironment.tostring ());//empty the code generatedthis. Generationenvironment.remove (0, this. Generationenvironment.length);} ADD Item to Solutionthis.addprojectitem (Dte,filepath);}}
