Question

I want to build my own class in C# that is initialized by multiple parameters with curly bracers, like string[]

string[] x = new string[] {
"string1",
"string2",
"string3"
}

Is it possible?

Edit I am sorry for not making myself clear. I wanted a class that can be initialized in an elegant way, with variable amount of parameters.

To support collection initializer syntax, your class needs to implement IEnumerable and have a public Add method.

Example:

class MyClass : IEnumerable<int>
{
    public void Add(int value) { ... }

    public IEnumerator<int> GetEnumerator() { ... }

    IEnumerator IEnumerable.GetEnumerator() { ... }
}

Usage:

var myClass = new MyClass { 1, 2, 3, 4, 5 };

Alternatively, you can define a constructor that takes a variable number of arguments. You can do this using the params keyword.

Example:

class MyClass
{
    public MyClass(params int[] args) { ... }
}

Usage:

var myClass = new MyClass(1, 2, 3, 4, 5);
