Question

我正在构建ASP.NET webforms中的库管理应用程序，我有一个表单应该将新用户添加到数据库中。但是当我尝试提交它时，页面只会闪烁，并且没有任何内容添加到数据库中。

这是aspx代码：

<div style="margin-top: 20px;">
    <form class="form-horizontal">
        <fieldset>
            <legend>Create new User</legend>
            <div class="form-group">
                <label for="inputFirstName" class="col-lg-2 control-label">First Name</label>
                <div class="col-lg-10">
                    <asp:TextBox class="form-control" ID="inputFirstName" placeholder="First Name" Style="margin-bottom: 10px;" runat="server"></asp:TextBox>
                </div>
            </div>

            <div class="form-group">
                <label for="inputLastName" class="col-lg-2 control-label">Last Name</label>
                <div class="col-lg-10">
                    <asp:TextBox class="form-control" ID="inputLastName" placeholder="Last Name" Style="margin-bottom: 10px;" runat="server"></asp:TextBox>

                </div>
            </div>


            <div class="form-group">
                <label for="inputPassword" class="col-lg-2 control-label">Adress</label>
                <div class="col-lg-10">
                    <asp:TextBox class="form-control" ID="inputStreet" placeholder="Street" Style="margin-bottom: 10px;" runat="server"></asp:TextBox>
                </div>
                <div class="col-lg-10 col-lg-offset-2">
                    <asp:TextBox class="form-control" ID="inputCity" placeholder="City" Style="margin-bottom: 10px;" runat="server"></asp:TextBox>
                </div>
                <div class="col-lg-10 col-lg-offset-2">
                    <asp:TextBox class="form-control" ID="inputCountry" placeholder="Country" Style="margin-bottom: 10px;" runat="server"></asp:TextBox>
                </div>

            </div>

            <div class="form-group">
                <label for="inputLastName" class="col-lg-2 control-label">Phone Number</label>
                <div class="col-lg-10">
                    <asp:TextBox class="form-control" ID="inputPhoneNumber" placeholder="Phone Number" Style="margin-bottom: 10px;" runat="server"></asp:TextBox>

                </div>
            </div>

            <div class="form-group">
                <div class="col-lg-10 col-lg-offset-2">

                    <asp:LinkButton runat="server" Text="Cancel" class="btn btn-default" />
                    <asp:LinkButton runat="server" Text="Submit" class="btn btn-primary" OnClik="Submit" />

                </div>
            </div>
        </fieldset>
    </form>
</div>

这是背后的代码：

private void Submit(object sender, EventArgs e)
    {
        string FirstName = inputFirstName.Text;
        string LastName = inputLastName.Text;

        string Street = inputStreet.Text;
        string City = inputCity.Text;
        string Country = inputCountry.Text;
        string PhoneNumber = inputPhoneNumber.Text;

        using (SqlConnection c = new SqlConnection("{LibraryContext}"))
        {
            c.Open();
            using (SqlCommand cmd = new SqlCommand("INSERT INTO LibUsers(UserFirstName,UserLastName,Adress,PhoneNumber) VALUES (@Fname, @Lname,@Adress,@PhoneNumber)"))
            {

                cmd.Parameters.AddWithValue("@Fname", FirstName);
                cmd.Parameters.AddWithValue("@Lname", LastName);

                //i know concatenation like this is bad
                cmd.Parameters.AddWithValue("@Adress", Street + " " + City + " " + Country);
                cmd.Parameters.AddWithValue("@PhoneNumber", PhoneNumber);

                cmd.ExecuteNonQuery();
            }
        }
    }

任何人都可以帮我解决这个问题吗？
提前致谢。

Answer 1

将OnClik="Submit"更改为OnClick="Submit"。

Answer 2

给出web.config文件中的连接字符串：

<connectionStrings>
    <add name="PubsConnectionString" connectionString="Server=(local);Database=pubs;trusted_connection=yes"/>
</connectionStrings>

获取值，然后将其传递给SqlConnection构造函数。

string connectionString = ConfigurationManager.ConnectionStrings["PubsConnectionString"].ConnectionString;
using (SqlConnection sqlConnection = new SqlConnection(connectionString))
{ ...

插入不会插入任何东西
