appconfig配置和连接问题？
我的appconfig这么些的:
<?xml version= "1.0 " encoding= "utf-8 " ?>
<configuration>
<appSettings>
<add key= "DBHost " value= "JF023\\SQLEXPRESS " />
<add key= "DBName " value= "wage " />
<add key= "DBUser " value= "sa " />
<add key= "DBPass " value= "jfis " />
</appSettings>
<connectionStrings>
</connectionStrings>
</configuration>
在程序中调用：
public string Constr()
{
string dbhost = System.Configuration.ConfigurationManager.AppSettings[ "DBHost "];
string dbname = System.Configuration.ConfigurationManager.AppSettings[ "DBName "];
string dbuser = System.Configuration.ConfigurationManager.AppSettings[ "DBUser "];
string dbpass = System.Configuration.ConfigurationManager.AppSettings[ "DBPass "];
string connStr= "server= "+dbhost+ ";database= "+ dbname+ ";uid= "+dbuser+ ";pwd= "+dbpass+ " ";
return connStr;
}
为什么不行啊！
[解决办法]
string dbhost = System.Configuration.ConfigurationManager.AppSettings[ "DBHost "];
ConfigurationManager改成ConfigurationSettings
