DataTable.Select Method (String, String)

Gets an array of all DataRow objects that match the filter criteria, in the specified sort order.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

public DataRow[] Select (
	string filterExpression,
	string sort
)
public DataRow[] Select (
	String filterExpression, 
	String sort
)
public function Select (
	filterExpression : String, 
	sort : String
) : DataRow[]

Parameters

filterExpression

The criteria to use to filter the rows.

sort

A string specifying the column and sort direction.

Return Value

An array of DataRow objects matching the filter expression.

To form the filterExpression argument, use the same rules for creating the DataColumn class's Expression property value. The Sort argument also uses the same rules for creating class's Expression strings.

The following example uses a filter expression to return an array of DataRow objects.

private void GetRowsByFilter()
{
    DataTable table = DataSet1.Tables["Orders"];

    // Presuming the DataTable has a column named Date.
    string expression = "Date > '1/1/00'";

    // Sort descending by column named CompanyName.
    string sortOrder = "CompanyName DESC";
    DataRow[] foundRows;

    // Use the Select method to find all rows matching the filter.
    foundRows = table.Select(expression, sortOrder);

    // Print column 0 of each returned row.
    for(int i = 0; i < foundRows.Length; i ++)
    {
        Console.WriteLine(foundRows[i][0]);
