Series[] series = new Series[10];

This line create an array. The new is just for creating array of series.

This line puts the value at the 0th index

series[0].Name = "Result Chart";

The problem is that you have not instantiated the object at 0th index. So you need to instantiated every index which you want to use.
Like if you want to use the 0th index then you will have to use

series[0] = new Series();

or just create a loop to instantiated every index as follows

for(int i=0;i<series.Count;i++)
{
   series[i] = new Series();
}
