示例

下面的代码示例演示如何检索LogonUserIdentity当前用户的属性并写出文本文件中每一项的值。The following code example shows how to retrieve the LogonUserIdentity property for the current user and write out the values of each item in a text file. 将此代码放在窗体的ACTION属性所引用的 ASP.NET 页上。Place this code on the ASP.NET page referenced by the form's ACTION attribute.

    *  to the folder.*/

注解

属性LogonUserIdentity将当前连接的用户的WindowsIdentity对象的属性和方法公开给 Microsoft Internet Information Services (IIS)。The LogonUserIdentity property exposes the properties and methods of the WindowsIdentity object for the currently connected user to Microsoft Internet Information Services (IIS). WindowsIdentity 通过LogonUserIdentity跟踪 IIS 请求标记公开的类的实例,并为当前在 ASP.NET 中处理的当前 HTTP 请求提供轻松访问此标记的权限。The instance of the WindowsIdentity class that is exposed by LogonUserIdentity tracks the IIS request token and provides easy access to this token for the current HTTP request being processed inside of ASP.NET. 自动创建WindowsIdentity类的一个实例,因此无需对其进行构造以获取对其方法和属性的访问权限。An instance of the WindowsIdentity class is automatically created so it does not need to be constructed to in order to gain access to its methods and properties.
