C# – SocketAsyncEventArgs and ReadAsync

c++networkingsockets

When using the "SocketAsyncEventArgs" class and ReadAsync, where do i put the read buffer and where do i put the send buffer? or can i only read or send at one time not both? I'm a bit confused.

Best Solution

I think you're looking for the Buffer property of SocketAsyncEventArgs. This tutorial explains how to use the SocketAsyncEventArgs class properly.

The MSDN article for the class contains some useful remarks and provides example code too (they're almost always a good start).

C# – the difference between String and string in C#

string is an alias in C# for System.String.
So technically, there is no difference. It's like int vs. System.Int32.

As far as guidelines, it's generally recommended to use string any time you're referring to an object.

e.g.

string place = "world";

Likewise, I think it's generally recommended to use String if you need to refer specifically to the class.

e.g.

string greet = String.Format("Hello {0}!", place);

This is the style that Microsoft tends to use in their examples.

It appears that the guidance in this area may have changed, as StyleCop now enforces the use of the C# specific aliases.

C# – Create Generic method constraining T to an Enum

Since Enum Type implements IConvertible interface, a better implementation should be something like this:

public T GetEnumFromString<T>(string value) where T : struct, IConvertible
{
   if (!typeof(T).IsEnum) 
   {
      throw new ArgumentException("T must be an enumerated type");
   }

   //...
}

This will still permit passing of value types implementing IConvertible. The chances are rare though.
