Follow the guidelines in How to Embed SQL Server Express in an Application. It covers everything you need, including pickiing up the right distribution, choosing an appropriate installation method (wpi vs. setup.exe) and how to configure the installation. the wiki even has a C# code on how to detect a previous Express instalation, how to invoke the WPI (Web Platform Installer) for SQL Express from C#:

System.Diagnostics.Process.Start(
  @"C:\Program Files\Microsoft\Web Platform Installer\webplatforminstaller.exe",
  " /id SQLExpress");

or using the "wpi://" URL handler:

System.Diagnostics.Process.Start("wpi://SQLExpress/");

or using the Web App Galery:

System.Diagnostics.Process.Start(
  "http://www.microsoft.com/web/gallery/install.aspx?appsxml=&appid=SQLExpress");

and, finally, using the SQL Express setup (recommended for advanced configuration):

System.Diagnostics.Process processObj = 
  System.Diagnostics.Process.Start(@"c:\temp\sqlsetup\setup.exe",

@"/q /Action=Install /Hideconsole /IAcceptSQLServerLicenseTerms=True 
 /Features=SQL,Tools /InstanceName=SQLExpress
 /SQLSYSADMINACCOUNTS=""Builtin\Administrators"" 
 /SQLSVCACCOUNT=""DomainName\UserName"" /SQLSVCPASSWORD=""StrongPassword""");

and it has the full list of setup parameters.

You can use msiexec.exe. You can simply install an MSI by passing the MSI path. Using command you can set whether to show UI during the installation or make it a silent installation,

string installCommandString = "/i {0} /qn";

• /qn: Set user interface level: None
• /qb: Set user interface level: Basic UI
• /qr: Set user interface level: Reduced UI
• /qf: Set user interface level: Full UI (default)

C# code

string installCommandString = "/i {0} /qn";

Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
process.StartInfo = startInfo;

startInfo.UseShellExecute = false;
startInfo.RedirectStandardError = true;

startInfo.FileName = "msiexec.exe";
startInfo.Arguments = string.Format(installCommandString, "SQL Server MSI Path");

process.Start();
