Dynamic Array Java program converted to C#

The folowing program was orignally in java. But i still get 1 error with the program in C#.

(the eror is listed in comment in the 2nd block of code).

namespace DynArray
{
public class DynArrayTester
{
    static void Main(string[] args)
    {
        DynArray da = new DynArray(5);

        for (int i = 1; i <= 7; i++)
        {
            da.setData(i, i);
            //da.put(0, 0);
            //da.put(6, 6);
        }
        Console.WriteLine(da);
    }

Change .length to .Length

Also, change the "data" parameter it's confusing having that being both the member array and a parameter in the same method.

this.data.length

ONE look into the documentation and you will see that the error is right. data is an array. An array does not have a property "length". Not ehte spelling. "length" is not "Length".

Check the documentation of .NET to find the proper spelling or property name.
