Updating a row in datatable

I think this is enough code to make sense of what I'm doing, but if more is needed just let me know and I can post it up as well.

in the inner loop after a match is found - but reverting the order of the 2 loops) - but leaving the complexity order to O(n^2).

If INSERT, UPDATE, or DELETE statements have not been specified, the Update method generates an exception.

However, you can create a Sql Command Builder or Ole Db Command Builder object to automatically generate SQL statements for single-table updates if you set the Select Command property of a . Then, any additional SQL statements that you do not set are generated by the Command Builder.

For instance you could write the following code to update the column "Foo" to be the value str Verse Code above instantiates a Data Row.
