问题描述

我在Oracle中拥有表格

I have table in Oracle

Create Table (
USERNAME                                 VARCHAR2(70),
PASSWORD                                 VARCHAR2(50),
EMAIL                                    VARCHAR2(30))

namespace abc
{
    public partial class Test1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {  
            //OracleConnection ora = new OracleConnection(conn);
            //ora.ConnectionString = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1521)))(CONNECT_DATA=(SID=glmjoy)));User Id=glmjoy;Password=glmjoy;";
            //string qry = "insert into test1  (username) values (@txtusername)";
            //OracleCommand cmd=new OracleCommand(qry,ora);
            //cmd.Parameters.Add("username", txtusername.Text);
            //ora.Open();
            //cmd.ExecuteScalar();
            //ora.Close();
            //-----------------

            if  (!IsPostBack == true)
            { inert();
            } ----------- I  am getting error here   
         protected void inert()
         {      //If a PostBack occured, then handle your Oracle Database call

                string conn = "";

                //Create an OracleDatabase object
                OracleConnection ora = new OracleConnection(conn);
                {
                    //Open your connection
                    conn.Open();
                    
                    //Build your actual statement (example demonstrating parameters)
                    string sql = "INSERT INTO test1  (username) VALUES (@username)";

                    //Builds your command that will be executed
                    OracleCommand cmd = new OracleCommand(sql, conn);

                    //Populates your Parameters (examples)
                    cmd.Parameters.AddWithValue("@Username", txtusername.Text);


                    //Execute your command
                    cmd.ExecuteNonQuery();
                }
        }
    }
}

推荐答案

那是因为你没有结束了页面加载事件...

That is because you have not ended the Page Load Event...

namespace abc
{
    public partial class Test1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if  (!IsPostBack)
            { 
                inert();
            }
        } // This is missing.
     
        protected void inert()
        {
            // All the function codes
        }
    }
}
