C＃ 解析 sln 文件

我的项目，编码工具需要检测打开一个工程，获取所有项目。但是发现原来的方法，如果存在文件夹，把项目放在文件夹中，那么是无法获得项目，于是我就找了一个方法去获得sln文件的所有项目。

原先使用的方法dte.Solution.Projects但是放在文件夹的项目获取不到，所以使用堆栈提供的方法。

首先添加引用 Microsoft.Build 注意版本

这里写图片描述

然后把我三个类放到项目，其实放两个就好了，具体参见我的github

注意要引用

     using System;
     using System.Collections.Generic;
     using System.Diagnostics;
     using System.IO;
     using System.Linq;
     using System.Reflection;

稍微说下上面代码，主要用的是反射。

用反射获得解析 sln 的 s_SolutionParser_parseSolution 他可以获得所有项目。

但是获得的项目路径是相对的，于是使用C＃相对路径转绝对路径，可以转换项目路径。

使用

输入工程文件名就好，输入工程名，会自动获得所有项目。

  Solution solution = new Solution(工程文件路径);

获得工程文件的所有项目

  foreach (var temp in solution.Projects)
  {


  }
