Example

The following example creates a new PgSqlParameter and displays the ParameterName.

csharp

public void CreatePgSqlParameter()
{
        PgSqlParameter myParameter = new PgSqlParameter("DName", PgSqlType.VarChar, 15, ParameterDirection.Output, true, 0, 0, "DName", DataRowVersion.Current, "DEVELOPMENT");
  MessageBox.Show(myParameter.ToString());
}

Visual Basic

Public Sub CreatePgSqlParameter()
  Dim myParameter As New PgSqlParameter("DName", PgSqlType.VarChar, 15, ParameterDirection.Output, True, 0, 0, "DName", DataRowVersion.Current, "DEVELOPMENT")
  MessageBox.Show(myParameter.ToString())
End Sub
