I'm working on a C# project, I want to use an anonymous Method Or Function that returns a value to a variable.
I tried this :
byte[] V;
V= new byte[]()
{
//Some code here
return new byte[]{0,1,2,3};
}
But I got errors
How can I use anonymous Method Or Function to returns a value to V variable ?
I want just to knw how can I use anonymous method tat returns a value to a variable.
There are a couple of opportunities, all having their own advantages and disadvantages.
a delegate
byte[] V;
V= new Func<byte[]>(() => ()
{
//Some code here
return new byte[]{0,1,2,3};
}();
a local function
void DoSomething()
{
byte[] V;
byte[]MyLocalFunction()
{
//Some code here
return new byte[]{0,1,2,3};
}
V = MyLocalFunction();
}
a normal private method with a name
Personally I prefer 3 the most, as you have a name that clearly describes what the method should do. 2 also has a name and in fact compiles to a private static method within your class, so it may seem appropriate as well. 1 just makes your code har to understand and read. There are use-caes for that, but in most cases I won´t suggest to use it.
So if you think there is some logic within a member that should be extracted in some way, you give it a name. This way you can easily extract that to another class later on, if you need to.
