asp.net form submition into oracle數據庫

Question

我很開心在asp.net中。我創建了一個表單。當我提交表單時，我需要將表單字段值插入到Oracle數據庫模式的表中。我正在使用Visual Studio 2012 Express。我已經將我的數據庫模式添加到數據庫瀏覽器。現在我需要一個代碼來從表單獲取數據並插入到表中。

Default.aspx的代碼：

這裏是插入數據的簡單方法，你可以將它修改爲您的需求

public void InsertToOracle(string value) 
     { 
      string oradb = "Data Source=ORCL;User Id=user;Password=password;"; 

      using (OracleConnection conn = new OracleConnection(oradb)) 
      { 
       conn.Open(); 
       OracleCommand cmd = new OracleCommand(); 
       cmd.Connection = conn; 
       cmd.CommandText = "Insert into Table1(ColumnName) VALUES(@ParameterName)"; 
       cmd.Parameters.Add(new OracleParameter("@ParameterName", value)); 
       var rowsUpdated = cmd.ExecuteNonQuery(); 

      } 
     } 

另外在asp.net web表單沒有使用需求的Request.Form

，而不是

tkt_category = Request.Form["TicketCategoryTextBox"]; 

使用

tkt_category = TicketCategoryTextBox.Text; 

代替

Activity_type = Request.Form["ActivityTypeDropDown"]; 

使用

Activity_type = ActivityTypeDropDown.SelectedValue; 

所有項目標有RUNAT =服務器已經準備好使用作爲一個對象變量
