问题描述

我是 Visual Studio 的新手.我目前正在创建一个登录表单.

I'm new to Visual Studio. I'm currently creating a Login form.

我有这个代码.

string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
try
{
    using (OdbcConnection connect = new OdbcConnection(connectionString))
    {
        connect.Open();
        OdbcCommand cmd = new OdbcCommand("SELECT username, password FROM receptionist", connect);
        OdbcDataReader reader = cmd.ExecuteReader();

        if (username_login.Text == username && password_login.Text == password)
        {
            this.Hide();
            MessageBox.Show("Invalid User", "Login Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            this.Close();
        }
        else 
            MessageBox.Show("Invalid User", "Login Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        connect.Close();
    }
}
catch (OdbcException ex)
{
    MessageBox.Show(ex.Message, "error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}

但是每当我尝试输入用户名和密码时,都会出现一个名为配置系统初始化失败的错误.我只是想知道这是什么问题,我该如何解决?

But whenever I try to type in the username and password there is an error called Configuration system failed to initialize. I'm just wondering what kind of problem is this and how could I solve this?

请帮忙.

推荐答案

确保你的项目中的配置文件(web.config 如果是 web,或者 app.config 如果是 windows)启动为:

Make sure that your config file (web.config if web, or app.config if windows) in your project starts as:

<?xml version="1.0"?>
<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" 
                      type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >

            <section name="YourProjectName.Properties.Settings" 
                     type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" 
                     requirePermission="false" />

        </sectionGroup>
    </configSections>
</configuration>

请注意,在 configuration 元素中,第一个子元素必须是 configSections 元素.

Note that inside the configuration element, the first child must be the configSections element.

section 元素的 name 属性中,确保替换了 YourProjectName 使用您的实际项目名称.

In the name property on section element, make sure you replace YourProjectName with your actual project's name.

碰巧我在类库项目中创建了一个 webservice,然后我将配置文件(为了带来端点配置)复制(覆盖)到我的 Windows 应用程序,我开始遇到同样的问题.我无意中删除了 configSections.

It happened to me that I created a webservice in a class library project, then I copied (overwriting) the config file (in order to bring the endpoints configuration) to my windows app and I started to have the same problem. I had inadvertently removed configSections.

对我有用,希望能帮到你

it worked for me, hope it helps
