Enumerate projects in a solution

[Pete Kane]

Anyone know how to enumerate all projects contained in a solution,
basically I want to loop through my solution(s) projects and add some
header info to all my "compileabl e" source files, I know how to retrieve
project items but need some help with the solution part

many thanks

Re: Enumerate projects in a solution

Hi Pete,

It seems that there isn`t a way of doing that by using the classes in
the MSBUILD API (Microsoft.Buil d.BuildEngine.D ll).

One of the open-ended issues that Microsoft left in MSBuild is the fact
that Solution files are *not* valid MSBuild files. So as far as I know
there is no way to use the MSBuild API to interpret a solution file
(although you can use it to build an entire solution - Project.Load()
works with a .sln file).

One suggestion would be to use a a logic that hacks the .sln internal
structure in order to discover what projects are part of the solution.
The following code shows a way to do that:


const string projectFileLoca tion = @"C:\MySolution .sln";
StreamReader sr = File.OpenText(p rojectFileLocat ion);

const string
matchProjectNam eRegex =
"^Project\\(\"( ?<PROJECTTYPEGU ID>.*)\"\\)\\s* =\\s*\"(?<PROJE CTNAME>.*)\"\\s *,\\s*\"(?<PROJ ECTRELATIVEPATH >.*)\"\\s*,\\s* \"(?<PROJECTGUI D>.*)\"$";

List<string> listOfProjects = new List<string>();

string lineText;
while ( (lineText = sr.ReadLine()) != null)
{
if (lineText.Start sWith("Project( "))
{
Match projectNameMatc h = Regex.Match(lin eText,
matchProjectNam eRegex);
if (projectNameMat ch.Success)
{

listOfProjects. Add(projectName Match.Groups["PROJECTRELATIV EPATH"].Value);
}
}
}

foreach (string project in listOfProjects)
{
ProcessProject( project);
}

sr.Close();

Notice that the code is trying to find the lines that begin with the
"Project(" string. Those lines describe a projet existing into the
solution. After that a regular expression is employed to extract the
path where the project file is located relative to the solution file.

Hello Fabio, that's what I do at the moment ( although not using regexes
), the method I use is IndexOf(".cspro j") parse parse etc..., however
your method is much more elegant, thanks very much
