generate EF model by System.Diagnostics.Process

Question

after read this article i tried generate EF model by System.Diagnostics.Process:

Process myProcess = new Process();
    var cs = "Data Source=.\\SQLEXPRESS; Initial Catalog=uqs; Integrated Security=SSPI";
    myProcess.StartInfo.FileName = @"C:\Windows\Microsoft.NET\Framework\v3.5\EdmGen.exe";
    myProcess.StartInfo.Arguments = "/mode:fullgeneration /c:"+cs+" project:School /entitycontainer:SchoolEntities /namespace:SchoolModel /language:CSharp ";
    myProcess.Start();

but i haven't get a result, because i can't do well formed arguments string. As I tried, there have many quotes. how to organize argument string?

Why do you want to call EdmGen from an application at runtime? — Daniel Brückner, Mar 16 '10 at 21:49
because, in one app user can create a database with arbitrary structure, and i want to use as data model entity framework. then create other classes, and web-interface by template. — loviji, Mar 16 '10 at 21:51
Is EF 4 an option? If so, you can use code-first, which is a better solution for this. — Craig Stuntz, Mar 17 '10 at 14:30
@Craig Stuntz: thanks. I'm using EF 4. please advise the link to information for familiarity. — loviji, Apr 26 '10 at 16:04

Point 1: I think you need at least some quotes around the connection string:

    myProcess.StartInfo.Arguments = "/mode:fullgeneration \"/c:"+cs+"\" project:School ...";

But do examine the resulting Arguments string in the debugger to see if everything is allright.

For point 2, see this SO question.

You just have to add double quotes around the connection string.

var cs = @"""Data Sour[...]rity=SSPI""";

Note the three double quotes at each end and the at.
