OleDbParameterCollection Class
.NET Framework 2.0
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)
Assembly: System.Data (in system.data.dll)
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 Function GetDataSetFromAdapter( _ ByVal dataSet As DataSet, ByVal connectionString As String, _ ByVal queryString As String) As DataSet Using connection As New OleDbConnection(connectionString) Dim adapter As 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 ex As Exception Console.WriteLine(ex.Message) End Try ' The connection is automatically closed when the ' code exits the Using block. End Using Return dataSet End Function
using System; 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;
