Many tasks require some setup in .NET Solutions: facade-type static utility class Example: Kwork.Helpers.Email.Send(to,from,subject,message); extension methods to commonly needed classes Example:”my string”.RightFromLast(”/”);

2. C# features I wish I knew…
”C# Features I wish I knew when I started my career after
graduation”
This is a case study on building a utility class
and the features needed. These are functions I wish our new
developers knew but often are missed in education
(I would have loved to know these, too, but I was educated on
C++, Java and Python…)

10. static void Method(out int i, out string s1, out string s2)
{
i = 44;
s1 = "I've been returned";
s2 = null;
}
static void Main()
{
int value;
string str1, str2;
Method(out value, out str1, out str2);
// value is now 44
// str1 is now "I've been returned"
// str2 is (still) null;
}

11. static bool Method(int divider)
{
return 1/ divider;
}
static bool TryMethod(int divider, out int i)
{
if(divider == 0) {
i = 0;
return false; }
i = 1/divider;
return true;
}
static void Main(int userValue)
{
int value;
if(TryMethod(userValue, out value))
Console.WriteLine(value);
}
