在VS2008扩展开发中，最重要的就是DTE对象。DTE对象提供了对扩展性模型中其他对象的访问。DTE是VS自动化模型中的顶级对象。
在按照http://www.cnblogs.com/yjf512/archive/2010/06/05/1752401.html中描述的创建VS AddIn插件后，能在Connect类中找到private DTE2 _applicationObject这个属性，对文件的各项操作就是从这个DTE2属性中开始：
以下方法可以在Exec方法中引用：
如何使用DTE2打开一个解决方案：
private
void
OpenSolution(
string
solutionFullName, DTE2 _applicationObject)
{
try
{
((DTE2)_applicationObject).Solution.Open(solutionFullName);
}
catch (Exception ex)
{
throw ;
}
}
{
try
{
((DTE2)_applicationObject).Solution.Open(solutionFullName);
}
catch (Exception ex)
{
throw ;
}
}
取得当前解决方案中的所有方法：
(其中包含了对Project的操作、对FileCodeModel的操作，对codeElement的操作)
private
CodeFunction2[] GetAllFunctionInCurrentCode(DTE2 _applicationObject)
{
List < CodeFunction2 > codeFuncs = new List < CodeFunction2 > ();
int projectCount = _applicationObject.Solution.Projects.Count;
try
{
for ( int i = 0 ; i < projectCount; i ++ )
{
Project project = _applicationObject.Solution.Projects.Item(i + 1 );
foreach (ProjectItem vsproject in project.ProjectItems)
{
if (vsproject.Name.Contains( " .cs " ))
{
FileCodeModel2 CM = (FileCodeModel2)vsproject.FileCodeModel;
foreach (CodeElement2 codeElement in CM.CodeElements)
{
if (codeElement.Kind == vsCMElement.vsCMElementNamespace)
{
CodeElement2 eleTemp = codeElement;
Queue < CodeElement2 > childElements = new Queue < CodeElement2 > ();
childElements.Enqueue(eleTemp);
while (childElements.Count != 0 )
{
CodeElement2 topEle = childElements.Dequeue();
if (topEle.Kind == vsCMElement.vsCMElementFunction)
codeFuncs.Add((CodeFunction2)topEle);
if (topEle.Children != null )
{
foreach (CodeElement2 childrenItem in topEle.Children)
{
childElements.Enqueue(childrenItem);
}
}
}
}
}
}
}
}
}
catch (Exception ex)
{
throw ;
}
return codeFuncs.ToArray();
}
{
List < CodeFunction2 > codeFuncs = new List < CodeFunction2 > ();
int projectCount = _applicationObject.Solution.Projects.Count;
try
{
for ( int i = 0 ; i < projectCount; i ++ )
{
Project project = _applicationObject.Solution.Projects.Item(i + 1 );
foreach (ProjectItem vsproject in project.ProjectItems)
{
if (vsproject.Name.Contains( " .cs " ))
{
FileCodeModel2 CM = (FileCodeModel2)vsproject.FileCodeModel;
foreach (CodeElement2 codeElement in CM.CodeElements)
{
if (codeElement.Kind == vsCMElement.vsCMElementNamespace)
{
CodeElement2 eleTemp = codeElement;
Queue < CodeElement2 > childElements = new Queue < CodeElement2 > ();
childElements.Enqueue(eleTemp);
while (childElements.Count != 0 )
{
CodeElement2 topEle = childElements.Dequeue();
if (topEle.Kind == vsCMElement.vsCMElementFunction)
codeFuncs.Add((CodeFunction2)topEle);
if (topEle.Children != null )
{
foreach (CodeElement2 childrenItem in topEle.Children)
{
childElements.Enqueue(childrenItem);
}
}
}
}
}
}
}
}
}
catch (Exception ex)
{
throw ;
}
return codeFuncs.ToArray();
}
