login with windows explorer failes sometimes - so use:

net use driveletter uncpath /USER:sambauser

net use z: \\192.168.1.4\varbak /USER:sambauser

Add Logfile To NLOG Config

        public static void AddLogFileToParent(string subLogDir)
        {
            var logDir = Path.Combine(subLogDir, "..");
            Trace.WriteLine("Adding logfile.txt to" + logDir);
            var config = LogManager.Configuration;

            var logFile = new FileTarget();
            config.AddTarget("file", logFile);

            logFile.FileName = logDir + "\\logfile.txt";
            logFile.Layout = "${date} | ${message}";

            var rule = new LoggingRule("*", LogLevel.Info, logFile);
            config.LoggingRules.Add(rule);

            LogManager.Configuration = config;
        }

init NLOG by Code

        private static  void InitLogger()

            // Step 1. Create configuration object
            var config = new LoggingConfiguration();
            // Step 2. Create targets and add them to the configuration
            var consoleTarget = new ColoredConsoleTarget();
            config.AddTarget("console", consoleTarget);
            var fileTarget = new FileTarget();
            config.AddTarget("file", fileTarget);

            consoleTarget.Layout = @"${date:format=HH\:mm\:ss} ${logger} ${message}";
            fileTarget.FileName = "${basedir}/file.txt";
            fileTarget.Layout = "${message}";
            // Step 4. Define rules
            var rule1 = new LoggingRule("*", LogLevel.Debug, consoleTarget);

            var rule2 = new LoggingRule("*", LogLevel.Debug, fileTarget);

MS Unit Test: use TestContext to get current TestName

1) insert Property TestContext into your TestClass - its filled by MSTest:

public TestContext TestContext { get; set; }

2) then use it in TestInitialize

        [TestInitialize]
        public void TestInitialize()
        {
            LOGGER.Info("Initialize Test {0} TestDir={1}", TestContext?.TestName, TestContext?.TestDir);
}

c# Lamda Ausdrücke, Action, Func, Anonyme Methoden (noname, keinName)

(x,y) => x*y;  kurz für (x,y) => { return x*y; } kurz für keinName(x,y){return x*y;}

x => x*x; //nur ein Parameter - kann Klammern weglassen

() => 2*3; //kein Parameter - brauche Klammern

(int x, int y) => x*y; //typisierte parameter

// Deklariere ein Delegate
delegate int RechenOperation(int a, int b);

// verwende Lambda um dem delegate eine Anonyme Methode zuzuweisen.
RechenOperation multipliziere = (x, y) => x * y;

// rufe das delegate auf, um es auszuprobieren
int resultat = multipliziere(4, 5);

Action

            var a1 = new Action(p1 => p1++);
            var a2 = new Action((p1) => { p1++; });

a1=a2

            var a3 = new Action(() =>;

                               {

                                   var x = 1;

                                   x++;

                               }

            );

Func

            var f1 = new Func(() => { return 1; });

            var f2 = new Func(() => 2);

Android 6 SD Karte partitionieren

adb shell

sm list-disks adoptable

sm partition disk:179,128 mixed 75

wird dann zu 75% als externe, 25% interner Speicher formatiert
