我目前在一个需要你帮助的特定问题上感到困惑。我的 asp.net 网站遇到了这个特殊问题。
无论出于何种原因，当用户试图将信息从文本框中保存到我的 .mdb 文件时，它都不会接受它。一切都编译得很好，我已经四次检查了所有的 ID 和字符串名称，一切似乎都与 .mdb、.c 文件和 aspx.cs 页面中的表上的内容相匹配。
这是输入信息的 .aspx 页面
<asp:Label ID="lblFirstName1" runat="server" align="left" Text="First Name: " Width="125px"></asp:Label>
<asp:TextBox ID="txtfirstName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="txtfirstName" ErrorMessage="First Name cannot be empty"></asp:RequiredFieldValidator>
<br />
<asp:Label ID="lblLastName1" runat="server" Text="Last Name: " Width="125px"></asp:Label>
<asp:TextBox ID="txtlastName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ControlToValidate="txtlastName" ErrorMessage="Last Name cannot be empty"></asp:RequiredFieldValidator>
<br />
<asp:Label ID="lblUserAddress1" runat="server" Text="Street Addres: " Width="125px"></asp:Label>
<asp:TextBox ID="txtstreetAddress" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server" ControlToValidate="txtstreetAddress"
ErrorMessage="Address cannot be empty"></asp:RequiredFieldValidator>
<br />
<asp:Label ID="lblcity1" runat="server" Text="City: " Width="125px"></asp:Label>
<asp:TextBox ID="txtcity" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator6" runat="server" ControlToValidate="txtcity"
ErrorMessage="City cannot be empty"></asp:RequiredFieldValidator>
<br />
<asp:Label ID="lblstate1" runat="server" Text="State: " Width="125px"></asp:Label>
<asp:TextBox ID="txtstate" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator7" runat="server" ControlToValidate="txtstate"
ErrorMessage="State cannot be empty"></asp:RequiredFieldValidator>
<br />
<asp:Label ID="lblzipCode1" runat="server" Text="Zip Code: " Width="125px"></asp:Label>
<asp:TextBox ID="txtzipCode" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator8" runat="server" ControlToValidate="txtzipCode"
ErrorMessage="Zip Code cannot be empty"></asp:RequiredFieldValidator>
这是 .cs 页面中用于保存到 .mdb 的信息
public static bool Saveneworder(string Database, string firstName, string lastName, string streetAddress, string city, string state, string zipCode )
{
bool recordSaved;
// Create a new Oledb Transaction object
OleDbTransaction myTransaction = null;
try
{
// Create a New Connection Object to the Access Database
OleDbConnection conn = new OleDbConnection("PROVIDER=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + Database);
conn.Open();
OleDbCommand command = conn.CreateCommand();
string strSQL;
// set the transaction object and start the transaction
myTransaction = conn.BeginTransaction();
command.Transaction = myTransaction;
strSQL = "Insert into tblOrder " +
"(firstName, lastName, streetAddress, city, state, zipCode) values ('" +
firstName + "', '" + lastName + "', '" + streetAddress + "', '" + city + "', '" + state +
"', '" + zipCode + "')";
// set the command text of the command object
command.CommandType = CommandType.Text;
command.CommandText = strSQL;
// Execute the insert statement
command.ExecuteNonQuery();
myTransaction.Commit();
// Close the Database connection
conn.Close();
recordSaved = true;
}
catch (Exception ex)
{
//Rollback the transaction if some failure occurs
myTransaction.Rollback();
recordSaved = false;
}
return recordSaved;
}
这是第一个将数据从文本框传输到 orderverified 页面的 aspx.cs 文件，该页面列出了信息未发布的 else 语句
protected void btnSubmit_Click(object sender, EventArgs e)
{
if (ValidateFields()) //if Validate fields method has returned true
{
Session.Add("txtfirstName", txtfirstName.Text);
Session.Add("txtlastName", txtlastName.Text);
Session.Add("txtstreetAddress", txtstreetAddress.Text);
Session.Add("txtcity", txtcity.Text);
Session.Add("txtstate", txtstate.Text);
Session.Add("txtzipCode", txtzipCode.Text);
Server.Transfer("orderverified.aspx");
}
并将信息转发到这个 aspx.cs 文件
protected void Page_Load(object sender, EventArgs e)
{
//So here we are initializing text property of the textbox "txtVerifiedInfo" after fetching the
//values from the session object
txtVerifiedInfo.Text = Session["txtfirstName"].ToString() +
"\n" + Session["txtlastName"].ToString() +
"\n" + Session["txtstreetAddress"].ToString() +
"\n" + Session["txtcity"].ToString() +
"\n" + Session["txtstate"].ToString() +
"\n" + Session["txtzipCode"].ToString()
;
// Check if the record is successfully saved in the tblOrder Table and prints the appropriate message in the text box txtVerifiedInfo
if (clsDataLayer.Saveneworder(Server.MapPath("App_Data\\WSC_DB.mdb" ),
Session["txtfirstName"].ToString(),
Session["txtlastName"].ToString(),
Session["txtstreetAddress"].ToString(),
Session["txtcity"].ToString(),
Session["txtstate"].ToString(),
Session["txtzipCode"].ToString() ))
{
txtVerifiedInfo.Text = txtVerifiedInfo.Text +
"\nThe Order successfully submitted!";
}
else
{
txtVerifiedInfo.Text = txtVerifiedInfo.Text +
"\n The order did not save, please return to the previous screen and verify all of your data is correct, thank you.";
}
在最后一页 - Orderverified.aspx 我有一个多行文本框，清楚地显示所有数据，但它返回我的 else 语句，它无法保存到 tblOrder
很抱歉发布了这么多代码，但我真的很困惑为什么这不能保存。
感谢您的阅读和您的时间
在进一步排除故障后，我尝试排除除了名字之外的所有内容，但它仍然不会发布。我觉得问题很可能出在 .cs 文件代码上，即插入到 tblOrder 中的 sql 语句
