Question

如何取得app.config中connectionStrings的值

Answer 1

1.先在程序中导入包using System.Configuration;
2.或是在右边项目名中添加外键引用 System.Configuraton;
xml文件配置如下：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configruations>
</configurations>
<connectionStrings>
<add name="DataBaseOwner" (数据库拥有者) connectionString="dbo"(类似sql)>
<add name="MySchoolConnectionString" connectionString=" Data Source=。;Initial Catalog=MySchool; User ID=sa; Password=12345 "
providerName=" System.Data.SqlClient "
</connectionStrings>
</configuration>
