Use the adapter's Update method to update the data. This overloaded method can take a DataTable as a parameter and will commit all the changes made to the data source. The name of the data table can be passed as an argument and can also be used to update the entire dataset in a more traditional manner. When using a data table as an argument to the Update method, the adapter evaluates the changes that have been made to the data table and executes the appropriate command for each row (INSERT, UPDATE, or DELETE).

The example below updates the Email of one of the Customers entries.

C#

using (StripeConnection connection = new StripeConnection(connectionString)) {
  StripeDataAdapter dataAdapter = new StripeDataAdapter(
    "SELECT Discount, Email FROM Customers", connection);

  dataAdapter.UpdateCommand = new StripeCommand(
    "UPDATE Customers SET Email = @Email " +
    "WHERE Id = @Id", connection);
 
  dataAdapter.UpdateCommand.Parameters.Add(new StripeParameter("@Email", DbType.String, "Email"));
  dataAdapter.UpdateCommand.Parameters.Add(new StripeParameter("@Id", DbType.String, "Id"));
  dataAdapter.UpdateCommand.Parameters[1].SourceVersion = DataRowVersion.Original;

  DataTable table = new DataTable();
  dataAdapter.Fill(table);

  DataRow firstrow = table.Rows[0];
  firstrow["Email"] = "[email protected]";

  dataAdapter.Update(table);

  Console.WriteLine("Rows after update.");
  
  foreach (DataRow row in table.Rows) {
    Console.WriteLine("{0}: {1}", row["Discount"], row["Email"]);
  }
}

VB.NET

Using connection As New StripeConnection(connectionString)
  Dim dataAdapter As New StripeDataAdapter(
    "SELECT Discount, Email FROM Customers", connection)
  
  dataAdapter.UpdateCommand = New StripeCommand(
    "UPDATE Customers SET Email = @Email " +
    "WHERE Id = @Id", connection)
  
  dataAdapter.UpdateCommand.Parameters.Add(new StripeParameter("@Email", DbType.String, "Email"))
  dataAdapter.UpdateCommand.Parameters.Add(new StripeParameter("@Id", DbType.String, "Id"))
  dataAdapter.UpdateCommand.Parameters(1).SourceVersion = DataRowVersion.Original
  
  Dim table As New DataTable()
  dataAdapter.Fill(table)
  
  Dim firstrow As DataRow = table.Rows(0)
  firstrow("Email") = "[email protected]"
  
  dataAdapter.Update(table)
  
  Console.WriteLine("Rows after update.")
  
  For Each row As DataRow In table.Rows
    Console.WriteLine("{0}: {1}", row("Discount"), row("Email"))
  Next
End Using
