Question

我有这段代码片段

public Version BuildVersion =Version.Parse(System.Web.Configuration.WebConfigurationManager.AppSettings["BuildVersion"].ToString());

读取以下appSetting条目

 <appSettings>
        <add key="BuildVersion" value="4.7.2.2" />
</appSettings>

这会引发异常

一旦部署到服务器，但它在VS2010 Web主机（ASP NET Development Server）上运行良好。

很可能没有将正确的配置文件部署到您的主机。

在ASP版本4中解析属性会导致FormatException
