Access cell value of datatable

Can anyone help me how to access for example value of first cell in 4th column?

a b c d
1 2 3 5
g n m l


for example, how to access to value d, if that would be datatable?

Thanks.

Answer

If you need a weak reference to the cell value:

object field = d.Rows[0][3]

or

object field = d.Rows[0].ItemArray[3]

Should do it

If you need a strongly typed reference (string in your case) you can use the DataRowExtensions.Field extension method:

string field = d.Rows[0].Field<string>(3);

(make sure System.Data is in listed in the namespaces in this case)

Indexes are 0 based so we first access the first row (0) and then the 4th column in this row (3)
