Arrays aliasing a portion.

Question

Hello,   I am new to C# but I have been researching a lot before posting.  Here is my issue which I have not found an open source answer to and I am hoping to resolve.   I have an array that is 20 rows by 5 columns.  It is static in size.   In the rows there is bar data from a stock market chart.   Layed out as follows.   Column 0 = Time 1 = Open 2 = High 3 = Low 4 = Close    This will be update through out the day.     I want to create and alias (not sure if this is the right word) for the following data block in order to analyse further elswhere.   I want to reference the "Close" column the last 10 rows only.  I do not need the other columns nor do I need anything below the 10 entry at this time.  I would like to create a constant or some other way of idenfying easily this block which will get passed to other sections of coding that I am working on.      Thank you

public enum EColumn
{
ETime = 0,
EOpen = 1,
EHigh = 2,
ELow = 3,
EClose = 4
}
public void DoSomething ( EColumn eType)
{
if (eType==EColumn.ETime)
...
}
