我有一个非常简单的页面，希望了解如何将文本框中的数据传递到我的过程中。我是一个新人，将参数从代码传递到数据库中，我有一页代码是
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="LastName" runat="server"></asp:TextBox>
<asp:TextBox ID="FirstName" runat="server"></asp:TextBox>
<asp:TextBox ID="Phone1" runat="server"></asp:TextBox>
<asp:TextBox ID="Phone2" runat="server"></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
<br />
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:TicketsConnectionString %>" SelectCommand="SELECT * FROM [Employee]"></asp:SqlDataSource>
</div>
</form>
</body>
</html>
和aspx代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
string connectionString = ConfigurationManager.ConnectionStrings["TicketsConnectionString"].ConnectionString;
protected void Button1_Click(object sender, EventArgs e)
{
DataSet ds = new DataSet();
SqlConnection con = new SqlConnection(connectionString);
SqlCommand cmd = new SqlCommand("InsertIntoEmployee", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@LastName", SqlDbType.VarChar).Value = LastName.Text;
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar);
cmd.Parameters.Add("@Phone1", SqlDbType.VarChar);
cmd.Parameters.Add("@Phone2", SqlDbType.VarChar);
cmd.Parameters["@LastName"].Value = LastName.Text;
cmd.Parameters["@FirstName"].Value = FirstName.Text;
cmd.Parameters["@Phone1"].Value = Phone1.Text;
cmd.Parameters["@Phone2"].Value = Phone2.Text;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
}
web.config看起来像这样
<?xml version="1.0"?>
<!--

<configuration>
<connectionStrings>
<add name="TicketsConnectionString" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename="C:\Users\Asya\Documents\Visual Studio 2012\WebSites\WebSite6\App_Code\Tickets.mdf";Integrated Security=True;Connect Timeout=30"
providerName="System.Data.SqlClient" />
</connectionStrings>
<system.web>
<compilation debug="true" targetFramework="4.5"/>
<httpRuntime targetFramework="4.5"/>
</system.web>
</configuration>
当我将简单数据传递到我的程序时，它将引发错误
An SqlParameter with ParameterName '@LastName' is not contained by this SqlParameterCollection.
如何解决这个问题？因为在DB端过程完美运行
正如我之前所说，我真的很陌生。我解决了以前的问题，但这里又解决了一个
The string was not recognized as a valid DateTime. There is an unknown word starting at index 0.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.FormatException: The string was not recognized as a valid DateTime. There is an unknown word starting at index 0.
Source Error:
Line 34: cmd.Parameters["@Phone2"].Value = Phone2.Text;
Line 35: con.Open();
Line 36: cmd.ExecuteNonQuery();
Line 37: con.Close();
Line 38:
我使用的程序
procedure InsertIntoEmployee
@LastName Nvarchar (25) ,
@FirstName Nvarchar (25) ,
@Phone1 Nvarchar (25) ,
@Phone2 Nvarchar (25)
as
insert into Employee (LastName , FirstName,Phone1,Phone2)values (@LastName,@FirstName,@Phone1,@Phone2);
当我在Db一侧运行程序时
EXEC InsertIntoEmployee N'петров', N'петр', 99999999,null它工作完美，但从asp.net方面来看，它会抛出错误
最佳答案
尝试这个
protected void Button1_Click(object sender, EventArgs e)
{
DataSet ds = new DataSet();
SqlConnection con = new SqlConnection(connectionString);
SqlCommand cmd = new SqlCommand("InsertIntoEmployee", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@LastName", SqlDbType.NVarChar(MAX)).Value = LastName.Text;
cmd.Parameters.Add("@FirstName", SqlDbType.NVarChar(MAX)).Value = FirstName.Text;
cmd.Parameters.Add("@Phone1", SqlDbType.NVarChar(MAX)).Value = Phone1.Text;
cmd.Parameters.Add("@Phone2", SqlDbType.NVarChar(MAX)).Value = Phone2.Text;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
// gvQuarterlyReport.DataBind();
}
