So I've been trying to figure out how to populate an array with an object I have created in C#. I found this cod开发者_JAVA技巧e sample which explains a bit about what I need to do.
for (int i = 0;i<empArray.Length;i++)
{
empArray[i] = new Employee(i+5);
}
But what happens if I pass more than one parameter into my constructor? Will this look any different? Like empArray[i] = new Employee(i, j, k); and so on. And if so how will read these objects out of the array, to say the Console. Would
Console.WriteLine(empArray[i])
do the trick if the object has more than one variable passed into it, or will I need a multi dimensional array? I apologize for all the questions, just a little new to C#.
The parameters passed in to the constructor are simply information for the object to initialize itself. No matter how many parameters you pass in, only a single Employee
object will come out, and that object will be put in empArray[i]
.
You will always access the Employee
objects using empArray[<index>]
where index is an integer where 0 <= index < empArray.Length.
Console.WriteLine
takes a string or any object with a ToString()
method on it. So if the Employee
object implements ToString()
, then Console.WriteLine(empArray[i])
will work. You might implement ToString()
like this:
public string ToString()
{
return String.Format("{0} {1}", this.FirstName, this.LastName);
}
Yes, this would work. In the statement array[i] the i is used as a reference to a position in a array, and has nothing to do with the actual contents of the object.
