使用passwordbox内容验证SQL数据库数据| WPF | C＃|产品密钥 [英] Verifying SQL database data with passwordbox content | WPF | C# | product key

问题描述

大家好，如果用户输入正确的产品密钥，我试图让我的登录窗口只继续输入一串代码。



输入正确的产品密钥时需要执行的代码：

Hi all, I'm trying to get my login window to only continue a string of code if the user enters 1 of the correct product keys.

The code that I need to execute when 1 of the correct product keys are entered:

MainWindow win2 = new MainWindow();
win2.Show();
this.Close();

如果有办法向我展示如何在我的服务器上设置我的数据表，那就太棒了。

----------------------------------

这是当ANYTHING在密码框中时当前激活的代码：

If there's a way of showing me how I should set out my data table on my server as well, that would be great.
----------------------------------
Here's the code that currently activates when ANYTHING is in the password box:

private void TextBox_TextChanged(object sender, TextChangedEventArgs e)
        {
            MainWindow win2 = new MainWindow();
            win2.Show();
            this.Close();
        }

------------------------------ ----



我的尝试：



我'看着谷歌，但我似乎无法找到适用于密码箱的东西。 （我是WPF的新手＃）

----------------------------------

What I have tried:

I've looked all over Google, but I can't seem to find something that works with password boxes. (I'm quite new to WPF c#)

推荐答案

在这里试试：密码存储：如何做到这一点。 [ ^ ]

在不知道SQL Server表的情况下，SQL问题很难帮到你结构，显然。包括具体细节。



PasswordBox类型控件支持属性密码服务器端，但出于安全原因不能绑定它。详情请见： [ ^ ]



哪个我想知道你为什么要对文本框的文本更改事件采取行动？

显然你不想对每一个改变采取行动，但是直到按下一些按钮才会动作。

You SQL question is hard to help you with without knowing your SQL server table structure, obviously. Do include for specifics.

A PasswordBox type control supports a property Password server side, however it cannot be bound to for security reasons. See details: [^]

Which me wonder why you're acting on the text changed event of a textbox?
Clearly you don't want to act on every change but not until for instance some button is pressed.

<StackPanel Margin="10">
       <Label>Text:</Label>
       <TextBox />
       <Label>Password:</Label>
       <PasswordBox id="MyPasswordBox" />
   </StackPanel>

然后在代码隐藏中你可以简单地访问它

and then on the codebehind you can simply access it with

string password = MyPasswordBox.Password;

其中包含在像对象这样的事件中，请记得首先将其拆箱。

Of it is boxed in an event like object, remember to unbox it first.

var pwBox = (PasswordBox)sender;

但如果发件人不要试试是你的按钮事件;）

But don't try it if you sender is on your button event ;)
