IPrincipal Interface

Summary

Represents the security principal for which the calling code is executing. A principal is an entity that can be authenticated, such as a user or a process.

Interface Members

The IPrincipal interface defines the following members:

• Identity property
• IsInRole method

Identity Property

Gets the IIdentity object associated with the current principal.

Syntax:

IIdentity Identity { get; }

Property Value:
An IIdentity object that represents the authenticated identity of the caller.

IsInRole Method

Determines whether the current principal is a member of the specified role.

Syntax:

bool IsInRole(string role);

Parameters:

• role: A string representing the name of the role to check.

Return Value:
true if the principal is a member of the specified role; otherwise, false.

This method is used to enforce role-based security. For example, you can check if a user belongs to an "Administrator" role before allowing them to perform an action.
