把路径设置为全局变量

Posted 2020-08-21 ping的故事

配置文件web.config

<appSettings>
<add key="webpages:Version" value="3.0.0.0" />
<add key="webpages:Enabled" value="false" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusivejavascriptEnabled" value="true" />
<add key="PictureURL" value="C:/SavePicture"/>
</appSettings>

定义全局变量的类

public class Helper
{
public static string ConstURL ;

static Helper()
{
ConstURL =ConfigurationManager.AppSettings["PictureURL"];
}
}
