[RESOLVED] [NOOB] Simple ado.net question

How do I add data that is in memory to a dataset so that I can execute sql queries on it in order to return something that I can manage in a while or foreach loop?

Basically I have a file with data, that I'd like to be able to execute sql on to sort it. Something along these lines

while(not EOF)
{
Read data from file
add data to dataset
}

execute query on dataset

foreach row in dataset
{
create a treeview node for row.field
}

This should be simple.

Nevermind. I figured it out.




Create a dataset

DataSet dataset = newDataSet("My Dataset");



Create a table

DataTable datatable = dataKeyLog.Tables.Add("My Data Table");



Add columns to table

datatable.Columns.Add("Column 1");

datatable.Columns.Add("Column 2");

datatable.Columns.Add("Column 3");



Create a new row

DataRow row = datatable.NewRow();



Populate the new row with data

row["Column 1"] = "whatever data is appropriate"

row["Column 2"] = "whatever data is appropriate"

row["Column 3"] = "whatever data is appropriate"



Add the row to the table

datatable.Rows.Add(row);



Create a data view

DataView dataview = newDataView();

dataview.Table = datatable;
