使用excellibrary C＃隐藏excel列

问题描述

我已下载并在编码中使用了excellibrary。我需要帮助从数据库调用我的函数到excel。我无法隐藏某些列，例如id号。希望你能帮助我。我还需要帮助如何让多个数据库进入同一个excel。

以下是我的编码

  public   void  load_table_exec（） //  这用于自动加载表//使用女性 
 {
  string  constring =   datasource = localhost; port = 3306; username = root; password =; 
 MySqlConnection conDataBase =  new  MySqlConnection（constring）; 
 MySqlCommand cmdDataBase =  new  MySqlCommand（  select *来自database1.example;，conDataBase）;  //    
 
  try  
 {
 MySqlDataAdapter sda =  new  MySqlDataAdapter（）; 
 sda.SelectCommand = cmdDataBase; 
 DataTable dbdataset =  new  DataTable（）; 
 sda.Fill（dbdataset）; 
 BindingSource bSource =  new  BindingSource（）; 
 
 bSource.DataSource = dbdataset; 
 dataGridView1.DataSource = bSource; 
 sda.Update（dbdataset）; 
 
 DataSet ds =  new  DataSet（  New_DataSet）; 
 ds.Locale = System.Threading.Thread.CurrentThread.CurrentCulture; 
 sda.Fill（dbdataset）; 
 ds.Tables.Add（dbdataset）; 
 
 ExcelLibrary.DataSetHelper.CreateWorkbook（  MyExcelFile.xls，ds） ; 
 
} 
  catch （例外情况）
 {
 MessageBox.Show（ex.Message）; 
}
