web|字符串|字符串
web.config中的文件如下:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="constring" value="integrated security=SSPI;data source=localhost;initial catalog=教务管理系统" />
</appSettings>
<system.web>
。。。。。。。。。
</system.web>
</configuration>
访问如下:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'在此处放置初始化页的用户代码
If Not IsPostBack Then
Dim str As String = ConfigurationSettings.AppSettings("constring")
Dim con As New SqlClient.SqlConnection(str)
da.SelectCommand.Connection = con
da.Fill(daset, "课程信息")
dagrid.DataSource = daset.Tables("课程信息")
dagrid.DataBind()
End If
End Sub
