What are the uses of "using" in C#?
(29 answers)
Closed 4 years ago.
In C# one can type the using verb in line width the code sometimes, like
using (textwriter){ ..... }
I like that writing style and am wondered what is required to allow that for my own Api's.
As long as your objects are IDisposable then you can use it with the using statement.

In Java I can check if a method named "addNumbers" exists in a class "Calculate" by doing this:
Class<?> c = Class.forName("com.example.package.Calculate");
Method m = c.getMethod("addNumbers", int.class, int.class);
m.invoke(5,7)
What is the C# equivalent for this example?

Sorry for the silly question, but I came across the following C# code and I'm wondering what the [Flags] portion is and what it does.
[Flags]
public enum UserFlags
{
//...
}
Thank you in advance.
It's a class attribute. There are also method attributes for example.
You can even write your own
They are usually used to define meta information or behaviour about a class or method and can be read using reflection.

I saw this answer, The problem is - so I also need to know what type of encoder to use for getting the correct string - it may be in UTF\UTF8\ANSI.
Here is a example from the immediate window.
Encoding.Unicode.GetString(combinedBuf)
"믯ힿ힜힕�"
Encoding.UTF8.GetString(combinedBuf)
"שלום"
