推荐答案

您非常需要拿起一本有关Visual Studio和数据库连接的书并仔细阅读.
这是最好的学习方法.

You seriously need to pick up a book on Visual Studio and database connectivity and go through it.
That is the best way to learn.

我认为您可能会从编写这样的教程中受益.

I think you would probably benefit from doing a tutorial like this one.

您需要在配置文件中添加代码

you need to add a code at config file

<connectionStrings>
        <add name="ConnectionString" connectionString="Data Source=localhost;Initial Catalog=Databasename;Persist Security Info=True;User ID=sa;Password=sa"/>
	</connectionStrings>

该代码在VB中

昏暗的ConnectionString作为String = System.Configuration.ConfigurationManager.ConnectionStrings("ConnectionString").ToString()

现在，您可以在数据源中插入/更新/删除所需的任何内容

This Code is in VB

Dim ConnectionString As String = System.Configuration.ConfigurationManager.ConnectionStrings("ConnectionString").ToString()

Now You can insert/update/delete whatever you want at datasource

Dim SqlAdapter As New SqlDataAdapter("Select * From Test ", ConnectionString)
               Dim SqlDataset As New DataSet
               SqlAdapter.Fill(SqlDataset)
