VB.Net App.config访问 [英] VB.Net App.config access

问题描述

你好！

我看到了关于如何从app.config访问连接字符串的代码片段

hello!
I saw this code snippet on how to access the connection string from the app.config

Db.ConnectionString = ConfigurationManager.ConnectionStrings["con"].ToString();

我的问题是它对VB.Net无效...任何人都可以帮助我吗？

my problem is it does not work for VB.Net... can anyone help me?

推荐答案

嗨


也许你没有使用System.Configuration命名空间：

Hi
Maybe you did not using System.Configuration namespace :

 <configuration>
  <connectionstrings>
    <add name="DBConnectionString">
      connectionString="Data Source=Manoj;Initial Catalog=Test;Persist Security Info=True;User ID=sa;Password=admin123"
      providerName="System.Data.SqlClient" />
  </add></connectionstrings>
</configuration>

using System.Configuration;

string nwConn = System.Configuration.ConfigurationManager.ConnectionStrings[1].ToString();

但是你有很多不同的解决方案可以从app.config读取连接字符串，例如关注这些链接：

连接字符串App.Config

连接字符串和配置文件

连接字符串和应用程序配置



最好的问候。

However you have many different solutions for reading connection string from app.config for example follow of these links:
Connection string App.Config
Connection Strings and Configuration Files
connection string and app config

Best Regards.

Dim dbconn As New SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("con"))

<configuration>
  <appsettings>
    <add key="con" value="put your connection string here" />
  </appsettings></configuration>
