User.IsInRole Method

  • Reference

Definition

Namespace:
Microsoft.VisualBasic.ApplicationServices
Assembly:
Microsoft.VisualBasic.dll
Assembly:
Microsoft.VisualBasic.Forms.dll

Determines whether the current user belongs to the specified role.

Overloads

IsInRole(BuiltInRole)

Determines whether the current user belongs to the specified role.
IsInRole(String)

Determines whether the current user belongs to the specified role.

IsInRole(BuiltInRole)

Determines whether the current user belongs to the specified role.

public:
 bool IsInRole(Microsoft::VisualBasic::ApplicationServices::BuiltInRole role);
public bool IsInRole (Microsoft.VisualBasic.ApplicationServices.BuiltInRole role);
member this.IsInRole : Microsoft.VisualBasic.ApplicationServices.BuiltInRole -> bool
Public Function IsInRole (role As BuiltInRole) As Boolean

Parameters

role
BuiltInRole

The built-in Windows role for which to check membership.

Returns

Boolean

True if the current user is a member of the specified role; otherwise, False.

Examples

This example checks if the user is an administrator before accessing a resource.

If My.User.IsInRole( 
        ApplicationServices.BuiltInRole.Administrator) Then
    ' Insert code to access a resource here.
End If

Remarks

The My.User.IsInRole method allows your code to determine if the current user is a member of the specified role.

The overload of the My.User.IsInRole method that takes a string provides easy access to the IsInRole method of the current principal.

The overload of the My.User.IsInRole method that takes a BuiltInRole enumeration behaves differently, depending on the current principal. If it is a Windows user principal (WindowsPrincipal), this function converts role to the equivalent WindowsBuiltInRole enumeration and returns the result of calling IsInRole. If the current principal is any other principal, this function passes the name of the enumeration value in role to the principal's IsInRole method.

Note

The exact behavior of the My.User object depends on the type of the application and on the operating system on which the application runs. For more information, see the User class overview.
