OleDbParameterCollection Class

Represents a collection of parameters relevant to an OleDbCommand as well as their respective mappings to columns in a DataSet.

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

public sealed class OleDbParameterCollection : DbParameterCollection
public final class OleDbParameterCollection extends DbParameterCollection
public final class OleDbParameterCollection extends DbParameterCollection

The number of parameters in the collection must equal the number of parameter placeholders within the command text, otherwise the .NET Framework Data Provider for OLE DB might raise an error.

The following example creates multiple instances of OleDbParameter through the OleDbParameterCollection collection within the OleDbDataAdapter. These parameters are used to select data within the data source and place the data in the DataSet. This example assumes that a DataSet and an OleDbDataAdapter have already been created with the appropriate schema, commands, and connection.

public DataSet GetDataSetFromAdapter(
    DataSet dataSet, string connectionString, string queryString)
{
    using (OleDbConnection connection =
               new OleDbConnection(connectionString))
    {
        OleDbDataAdapter adapter =
            new OleDbDataAdapter(queryString, connection);

        // Set the parameters.
        adapter.SelectCommand.Parameters.Add(
            "@CategoryName", OleDbType.VarChar, 80).Value = "toasters";
        adapter.SelectCommand.Parameters.Add(
            "@SerialNum", OleDbType.Integer).Value = 239;

        // Open the connection and fill the DataSet.
        try
        {
            connection.Open();
            adapter.Fill(dataSet);
        
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        
        // The connection is automatically closed when the
        // code exits the using block.
    
    return dataSet;

using System.Data;
using System.Data.OleDb;

class Class1
{
    static void Main()
    {
        //        string x = "Provider=SQLOLEDB;Data Source=(local);Integrated Security=SSPI;Initial Catalog=Northwind";
    

    public DataSet GetDataSetFromAdapter(
        DataSet dataSet, string connectionString, string queryString)
    {
        using (OleDbConnection connection =
                   new OleDbConnection(connectionString))
        {
            OleDbDataAdapter adapter =
                new OleDbDataAdapter(queryString, connection);

            // Set the parameters.
            adapter.SelectCommand.Parameters.Add(
                "@CategoryName", OleDbType.VarChar, 80).Value = "toasters";
            adapter.SelectCommand.Parameters.Add(
                "@SerialNum", OleDbType.Integer).Value = 239;

            // Open the connection and fill the DataSet.
            try
            {
                connection.Open();
                adapter.Fill(dataSet);
            
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            
            // The connection is automatically closed when the
            // code exits the using block.
        
        return dataSet;
