```
var col = readBatch.Column(0);
```
Here `col` is an `IArrowArray`. In order to read the values from an array,
you need to know which type of data is contained in the array. You can do `as`
or `is` type checks for each type, or if you know the type, you can just cast.
In your example above, it is an `Int32Array`, so casting to that you can now
get the `.Values` property, which is a `ReadOnlySpan<int>` that you can loop
through:
```C#
IArrowArray col = readBatch.Column(0);
Int32Array intArray = (Int32Array)col;
ReadOnlySpan<int> values = intArray.Values;
for (int i = 0; i < values.Length; i++)
{
Console.WriteLine(values[i]);
}
```
