您需要添加一個(gè)引用System.Configuration，然后使用：
System.Configuration.ConfigurationManager.
ConnectionStrings["connectionStringName"].ConnectionString;

C＃
// Add a using directive at the top of your code file
using System.Configuration;
// Within the code body set your variable
string cs = ConfigurationManager.ConnectionStrings["connectionStringName"].ConnectionString;
VB
' Add an Imports statement at the top of your code file
Imports System.Configuration
' Within the code body set your variable
Dim cs as String = ConfigurationManager.ConnectionStrings("connectionStringName").ConnectionString
