如何使用ASP.NET表单（文本框）传递karthik@domain.com和kars@domain.com？

string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=new_db;" + "UID=root;" + "PASSWORD=password;" + "OPTION=3";

OdbcConnection MyConnection = new OdbcConnection(MyConString);

OdbcCommand cmd = new OdbcCommand("UPDATE awm_create SET referral_email='karthik@domain.com' WHERE email='kars@domain.com'" , MyConnection);

MyConnection.Open();

cmd.ExecuteNonQuery();

Answer 1

您必须在Web表单中添加两个asp.net文本框控件，并在回发时（使用IsPostBack标志），您可以从PageLoad事件中的文本框中提取电子邮件地址...即：

private void Page_Load()
{
    if(Page.IsPostBack)
    {
      // add validation here for the text boxes if you need...
      string refEmail= txtReferralEmail.Text.Trim();
      string email = txtEmail.Text.Trim();

      //then you can do something like this:

      var sql = string.Format("UPDATE awm_create SET referral_email='{0}' WHERE email='{1}'", refEmail, email);

      OdbcCommand cmd = new OdbcCommand(sql , MyConnection);
      try{
           MyConnection.Open();
           cmd.ExecuteNonQuery();
      }Catch(Exception e){
           // log your exception or whatever you need to do
      }
    }
}

不要忘记你需要在你的aspx表单中添加两个文本框，名称为txtReferralEmail和txtEmail。

抱歉，我得到了答案......

string MyConString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=new_db;" + "UID=root;" + "PASSWORD=password;" + "OPTION=3";

OdbcConnection MyConnection = new OdbcConnection(MyConString);
           OdbcConnection MyConnection = new OdbcConnection(MyConString);
            OdbcCommand cmd = new OdbcCommand("UPDATE awm_create SET referral_email=? WHERE email=?" , MyConnection);

            cmd.Parameters.Add("@tb_refemail", OdbcType.VarChar, 255).Value = tb_refemail.Text.Trim();
            cmd.Parameters.Add("@tb_email", OdbcType.VarChar, 255).Value = lblemail.Text;

            MyConnection.Open();
            cmd.ExecuteNonQuery();
