在exe模式下获取长度不能小于零参数名称长度
更新：这是代码
string path = Application.StartupPath.Substring(0, Application.StartupPath.LastIndexOf("bin")); 例外文字：

仅当从exe文件运行应用程序时，才会发生以下错误。 当它在调试模式下运行时，它不会抛出exception。 如何摆脱这个错误？ 仅当用户单击表示上载图像选项的菜单项时才会发生此错误。
如果bin存在，你必须检查exe的路径
string path; if(Application.StartupPath.LastIndexOf("bin") >0) string path = Application.StartupPath.Substring(0, Application.StartupPath.LastIndexOf("bin")); else { string path = string.Empty MessageBox("Check your path : " + Application.StartupPath); }
如果你在iis服务器配置中遇到这个问题，那么简单的事情是改变web.config文件中的连接字符串，就像你的sql server名称和服务器名称一样，然后重新启动iis然后尝试加载它工作的页面
