Modify .csproj files programmatically

问题

I have source code of Entlib 5.0 and I need sign all assemblies using my own key (snk file).

The easiest way would be to open the EnterpriseLibrary.2010 solution file in Visual Studio 2010 and for each project, select Properties->Signing then select Sign the Assembly and finally select your key file.

But I don't want to manually do that then I could write a script to manually edit the project files and insert the following at the end of the current list of PropertyGroups:

<PropertyGroup>
    <SignAssembly>true</SignAssembly>
</PropertyGroup>
<PropertyGroup>
    <AssemblyOriginatorKeyFile>keyFile.snk</AssemblyOriginatorKeyFile>
</PropertyGroup>

Any helper class in C# or scripting if were better for do it easy and quick way?

回答1:

You can take a look at the Microsoft.Build.BuildEngine namespace MSDN Link

Sample code:

Engine eng = new Engine()
Project proj = new Project(eng);
proj.Load(FullProjectPath);
proj.SetProperty("SignAssembly", "true");
proj.Save(FullProjectPath);

I recently used something similar to make a series of changes across all of my company's .csproj files (over 200) instead of manually opening each project and making changes.

Hope this helps.
