C# – How to prompt the user to reboot in a .NET installation

cinstallationnetwindows-installer

I'm using Visual Studio 2008 to write an installation, and I'm a completely new to installations. I've created an installation and successfully written some custom actions using a C# assembly. One action sets a RunOnce registry value, and now I need to prompt the user to reboot when the installation finishes, but I have no idea how. I've read the Installer class documentation, but I can't find any mention of rebooting.

I'm assuming I need to somehow get down to being able to call MsiSetProperty and set a REBOOT property, but I don't know how to do that from my .NET installer project.

Thanks. I ended up using a post-build event to run a batch file with the following command. The hard part was tracking down WiRunSQL.vbs, which was in the "Windows SDK Components for Windows Installer Developers" download.

cscript "C:\Program Files\Microsoft SDKs\Windows\v6.0\Samples\SysMgmt\MSI\scripts\WiRunSQl.vbs" my.msi "INSERT INTO `Property`(`Property`, `Value`) VALUES ('REBOOT', 'F')"

C# – How to cast int to enum

From an int:

YourEnum foo = (YourEnum)yourInt;

From a string:

YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString);

// The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute
if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(","))
{
    throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.")
}

Update:

From number you can also

YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt);

C# – How to escape braces (curly brackets) in a format string in .NET

For you to output foo {1, 2, 3} you have to do something like:

string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);

To output a { you use {{ and to output a } you use }}.

Or now, you can also use C# string interpolation like this (a feature available in C# 6.0)

Escaping brackets: String interpolation $(""). It is new feature in C# 6.0.

var inVal = "1, 2, 3";
var outVal = $" foo {{{inVal}}}";
// The output will be:  foo {1, 2, 3}
