Looping

C# provides same for, do… while(), while statements as those of C++. Adding to that it supports foreach looping.

int[] a = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };

foreach (int i in a)
{
    Console.WriteLine("{0}", i.ToString());
}
  • TODO: Try to write examples in various cases and find out the underlying behavior.

Array

Think of an array as a sequence of elements, all of which are the same type.

  • Sample code
int[] a = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };

foreach (int i in a)
{
    Console.WriteLine("{0}", i.ToString());
}

for (int i = 0; i < a.Length; i++ )
{
    Console.WriteLine("{0}", a[i].ToString());
}

Anonymous Object

Interestingly, the following expression is possible in C# like the similar expression is so in Javascript. I am geussing that the type of the object is randomly named by compiler.

var car = new { CodeName = "gorgeous lynda", Location = 4 };
Console.WriteLine("{0}, {1}", car.CodeName, car.Location);

var train = new { CodeName = "kerr", Location = 3 };
train = car;

If every name and type of the member variable matches, assigning to other object is also possible.

Daily open source

I found [this][https://github.com/khellang/scriptcs-editor] helpful to see how to use objects associated with collections. But I don’t know how to deal with NuGet package manager, so I couldn’t complie this.
