asp.net表单下载到oracle数据库

Question

我是asp.net的初学者。我创建了一个表单。当我提交该表单时，我需要将表单字段值插入到oracle数据库模式的表中。我正在使用Visual Studio 2012 Express。我已经将数据库模式添加到数据库资源管理器中。现在我需要一个代码来从表单中获取数据并插入到表中。

Default.aspx代码：

    <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true"

请帮我完成表单操作。

Answer 1

这是插入数据的简单方法，您可以根据需要进行修改

 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表单中无需使用Request.Form

而不是

tkt_category = Request.Form["TicketCategoryTextBox"];

使用

tkt_category = TicketCategoryTextBox.Text;

而不是

Activity_type = Request.Form["ActivityTypeDropDown"];

使用

Activity_type = ActivityTypeDropDown.SelectedValue;

所有标有runat = server的项目都可以用作对象变量
