Nuget-Wie erstellt man ein Paket
1. Downloaden
2. Datei "nuget.exe" in Solutionordner kopieren
3. nuget.exe spec (bzw. ./nuget.exe spec) in Shell ausführen. (In GitGui sowie Powershell ist das 2. notwendig).
4. Paketdatei wie

C# Embedded resources for "installer" like behaviour-Example
http://stackoverflow.com/questions/859699/how-to-add-resources-in-separate-folders
Einfach die Ordner (Und Dateien --> Bilder, SQL-Skripte, ...) in Ordner einfügen, zum Projekt hinzufügen.
Dann bei allen auf "Embedded resource" stellen:
Für SQL:
public MainWindow()
{
InitializeComponent();
string commandText;
Assembly thisAssembly = Assembly.GetExecutingAssembly();
using (Stream s = thisAssembly.GetManifestResourceStream("TestAppInstaller.Resource.Test.Test.sql"))
{
using (StreamReader sr = new StreamReader(s))
{
commandText = sr.ReadToEnd();
}
}
Debug.Print($"SQL commando: {commandText}");
}
Für Bilder:
using(Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("<root namespace for the assembly>.<folder name>.<image file name>"))
{
pictureBox1.Image = Image.FromStream(stream);
}
Für Bilder:
private
void SetRedImage()
{
this.UiThreadInvoke(() => { PictureBox_Online.Image
= GetImage("SchichtbuchPlaner2.Images.Red.ico");
});
}
private
Image GetImage(string
path)
{
using (Stream
stream = GetStream(path))
{
return
new
Icon(stream).ToBitmap();
}
}
private
Stream GetStream(string
path)
{
return
Assembly.GetExecutingAssembly().GetManifestResourceStream(path);
