Question

public partial class _Default : System.Web.UI.Page
{

SqlConnection con = new SqlConnection("Data Source=JIMMY-PC;initial Catalog=jimmy;
                                   Integrated Security=true");

protected void Page_Load(object sender, EventArgs e)
{

}

protected void Button1_Click(object sender, EventArgs e)
{
    SqlCommand cmd = new SqlCommand("Insert into Employee ('First Name','Middle Name',
                     'Last Name','D O B','Sex','Address')values (@FName,@MName,@LName,
                      @DOB,@Sex,@Address)", con);
    {
        cmd.Parameters.AddWithValue("@Fname",TextBox1.Text);
        cmd.Parameters.AddWithValue("@Mname",TextBox2.Text);
        cmd.Parameters.AddWithValue("@Lname",TextBox3.Text);
        cmd.Parameters.AddWithValue("@DOB",TextBox4.Text);
        cmd.Parameters.AddWithValue("@Sex", RadioButton1.SelectedItem);
        cmd.Parameters.AddWithValue("@Address",TextBox5.Text);
        con.Open();
        //Response.Write("<script>alert('Registered successfully......!')</script>");
    }
    con.Close();
}

我是asp.net的新手，请帮帮我。我尝试使用cmd.executenonquery，但有一些错误......我的连接字符串有什么问题吗？

Answer 1

我们必须传递ListItem的selectedItem Text / Value。如果以下代码不适合您，请提供错误详细信息，并提及您调用此执行方法的位置。

cmd.Parameters.AddWithValue("@Sex", RadioButton1.SelectedItem.Text)
//OR
cmd.Parameters.AddWithValue("@Sex", RadioButton1.SelectedItem.Value)

Answer 2

最好像这样更改你的SqlCommand：

SqlCommand cmd = new SqlCommand("Insert into Employee ([First Name],[Middle Name],[Last Name],[D O B],[Sex],[Address])
values (@FName,@MName,@LName,@DOB,@Sex,@Address)", con);

Answer 3

 con.Open();
            string Title = ddl_title.SelectedValue.ToString();
            string FirstName = txtname.Text;
            string MiddleName = txtmiddlename.Text;
            string LastName = txtlastname.Text;
            string Gender = ddl_gender.SelectedValue.ToString();
            string DateOfBirth = txtdateofbirth.Text;
            string Age = txtage.Text;
            string Cast = txtcast.Text;
            string Address = txtaddress.Text;
            string City = txtcity.Text;
            string Area = txtarea.Text;
            string PinCode = txtpincode.Text;
            SqlCommand cmd = new SqlCommand("Insert Into AddNewMemberWomenExecutiveCommittee Values('"+Title+"','"+FirstName+"','"+MiddleName+"','"+LastName+"','"+Gender+"','"+DateOfBirth+"','"+Age+"','"+Cast+"','"+Address+"','"+City+"','"+Area+"','"+PinCode+"')", con);


            int i = cmd.ExecuteNonQuery();
            if (i == 1)

                Response.Write("Insert Successfully");
            con.Close();
            GetData();

(1)con.open();//----->open the connection (2)SqlCommand cmd= new SqlCommand("Query,con");//--->command object (3)cmd.ExecuteNonQuery();----->function for insert, update, delete (4)con.close();-------->close the connnection, where con is connection object

将值插入表中
