Checking CustomErrors turned on in Code

问题

Is it possible to check weather custom errors is turned on or off in the code on web application runtime.

回答1:

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

HttpContext.Current.IsCustomErrorEnabled

回答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());

回答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;
}
