vs 2005添加web.config连接数据库字符串，获取的字符串为空

你为什么不用key value呢？直接在web.config里

<configuration>

<appSettings>

<add key="DataBaseConnection" value="uid=sapwd=Data Source=localhostdatabase=Data_Business" />

<!--<add key="DataBaseConnection" value="uid=sapwd=saData Source=EB9C771CA1504A6\CHENXIdatabase=Data_Business"/>-->

</appSettings>

<connectionStrings>

取的时候：ConfigurationManager.AppSettings["DataBaseConnection"]

你给出的这段代码是写在web.config里面的

<connectionStrings>

<add name="ConnectionString" connectionString="Data Source= xscjData Source=localhostUser Id=root Password=000000charset=utf8Integrated Security=TrueUser Instance=True" providerName="System.Data.SqlClient" />

</connectionStrings>

如果连接语句没问题的话

SqlConnection objconnection = new SqlConnection(strconnection)

SqlCommand cmd = new SqlCommand( c, objconnection )

cmd.ExecuteNonQuery()

一般这样就可以了
