WindowsIdentity.IsAnonymous Property

Definition

Gets a value that indicates whether the user account is identified as an anonymous account by the system.

public virtual bool IsAnonymous { get; }

Property Value

true if the user account is an anonymous account; otherwise, false.

Examples

The following code shows the use of the IsAnonymous property to detect whether the user account is identified as an anonymous account by the system. This code example is part of a larger example provided for the WindowsIdentity class.

if (!windowsIdentity.IsAnonymous)
{
    propertyDescription += " is not an Anonymous account";
}

Remarks

The IsAnonymous property detects both the Windows anonymous identity and the anonymous identity that is returned by the GetAnonymous method.

Anonymous accounts are typically only encountered only from within ASP.NET-based applications when anonymous access is allowed by Internet Information Services (IIS).
