检查Code中的CustomErrors已打开

Question

是否可以在Web应用程序运行时的代码中检查天气自定义错误是打开还是关闭。

Answer 1

I've figured out how to do it it's in...

HttpContext.Current.IsCustomErrorEnabled

Answer 2

You can use WebConfigurationManager.OpenWebConfiguration to obtain the configuration for the website, then use that to get the custom errors block:

Configuration configuration =
    WebConfigurationManager.OpenWebConfiguration(null);

CustomErrorsSection customErrorsSection =
    configuration.GetSection("system.web/customErrors") as CustomErrorsSection;

Response.Write(customErrorsSection.Mode.ToString());

Answer 3

OpenWebConfiguration(null) or HttpContext.Current.IsCustomErrorEnabled(true) gave me false information, this however worked great Copy paste:

public static CustomErrorsMode GetRedirectMode()
{
    Configuration config = WebConfigurationManager.OpenWebConfiguration("/");

    return ((CustomErrorsSection)config.GetSection("system.web/customErrors")).Mode;
}
