Have you set a project reference to the System.Data assembly? Show the context of the errorline.

You need to create a connection[^] object

public void InsertRow(string myConnectionString) 
{
   // If the connection string is null, use a default.
   if(myConnectionString == "") 
   {
      myConnectionString = "Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=Northwind;" + 
      "Integrated Security=SSPI;quot;;
   }
   OleDbConnection myConnection = new OleDbConnection(myConnectionString);
   string myInsertQuery = "INSERT INTO Customers (CustomerID, CompanyName) Values('NWIND', 'Northwind Traders')";
   OleDbCommand myCommand = new OleDbCommand(myInsertQuery);
   myCommand.Connection = myConnection;
   myConnection.Open();
   myCommand.ExecuteNonQuery();
   myCommand.Connection.Close();
}

Solution 2

Have you included a reference to System.Data.dll under your project References, rather than just adding the relevant using line?
If not, right click on References, and select "Add reference..."
Follow the instructions from there.
