本篇文章中小編要介紹如何使用C#程式碼來與資料庫進行連結，並使用 C#資料庫語法新增與刪除 來將新增資料或刪除資料庫中的檔案，以下就跟著小編來看看這次程式碼的講解範例吧。
該如何與資料庫進行連結呢?
C#資料庫程式範例教學
新增欄位使用 INSERT 語法
刪除欄位使用 DELETE 語法
using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
/* 資料庫刪除 編號99 的資料 */
public void RTM_Info_Delete()
{
string constr = "Data source = 172.20.0.1; initial catalog = SIP_RTM; user id = Webb; password = Gt820000;";
string sqlStr = "DELETE FROM Temp_5111_Status WHERE [No.]=99";
try
{
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand(sqlStr))
{
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
}
}
catch (Exception)
{ }
}
