you have loop table anyway, can utilize linq-to-datatable short , readable code. assuming have strings only:

var columns = table.columns.cast<datacolumn>().tolist(); int totalcharactercount = table.asenumerable() .sum(r => columns.sum(c => r.field<string>(c).length));

the inner columns.sum calculates , sums length of strings in each column of 1 datarow, outer sum calculates total-sum, adds row's sum together.
