Find Max value from datatable

[mangogul (Christoph)]

Convert.ToInt32(dt.AsEnumerable().Max(Function(row) row("column1"))) works.

Any idea how can I compute the average?

vAvg = dt.AsEnumerable().Average(Function(row) row("column1")) gives an error.

Which kind of conversion must I perform to assign a decimal value to vAvg?
