C# ASP.Net-VB到.MDF的连接

我正在尝试在.net应用程序中使用VB更新我的数据库。我已经在我的应用程序代码文件夹中添加了一个数据集文件，并将我的数据库上载到其中。我似乎无法更新表并向其插入新行。（我不熟悉数据库）数据库文件是.mdf，我遵循了数据访问层（生成的sql语句）的说明

这是我的web.config文件：

<configuration>
  <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\CreatePatient.mdf;Integrated Security=True;User Instance=True"
      providerName="System.Data.SqlClient" />
    <add name="CreatePatientConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\CreatePatient.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
      providerName="System.Data.SqlClient" />
  </connectionStrings>

  <system.web>
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.0"/>
  </system.web>
</configuration>

其想法是填写帐户凭据并将其存储在数据库中。如果我遗漏了任何信息，请告诉我。我是stackoverflow、ASP.net和SQL的新手，需要帮助

您的代码缺少将数据插入数据库的调用

If IsValid Then
    Try
        Dim strSQL = "insert into CreatePatient  (Account, Password, FirstName, LastName, " & _
                 "Address, HomePhone, Mobile, City, State, Zip, Social, Age, Gender, " & _
                 "Height, Weight, Marital, Spouse) values (@Account, @Password, @FirstName, " & _
                 "@LastName, @Address, @HomePhone, @Mobile, @City, @State, @Zip, @Social, " & _
                 "@Age, @Gender, @Height, @Weight, @Marital, @Spouse)"
        Using CCSQL = new SqlConnection(ConfigurationManager.ConnectionStrings("CreatePatientConnectionString").ConnectionString)
        Using CCUser = new SqlCommand(strSQL, CCSQL)
            CCSQL.Open()
            CCUser.Parameters.Add("@Account", Data.SqlDbType.VarChar).Value = Account.Text
            ......
            CCUser.ExecuteNonQuery()
        End Using
        End Using
        Response.Redirect("ProcedureSelectionForm.aspx")
    Catch ex As Exception
        ErrorTXT.Text = ex.Message
    End Try
End If

我还附上了在a中创建

SqlConnection

和

SqlCommand

，以确保正确关闭和处理连接，并在出现异常时创建该命令

感谢您的帮助。你很高兴能帮上忙，作为这个网站的新用户，我建议你读一下这篇文章
