SmtpPermission.IsSubsetOf Method

Returns a value indicating whether the current permission is a subset of the specified permission.

Namespace:  System.Net.Mail
Assembly:  System (in System.dll)
public override bool IsSubsetOf(
	IPermission target
)

Parameters

target
Type: System.Security.IPermission

An IPermission that is to be tested for the subset relationship. This permission must be of the same type as the current permission.

Return Value

Type: System.Boolean
true if the current permission is a subset of the specified permission; otherwise, false.

Implements

IPermission.IsSubsetOf(IPermission)
ExceptionCondition
ArgumentException

target is not an SmtpPermission.

The current permission is a subset of the specified permission if the current permission specifies a state that is wholly contained by the specified permission. If this method returns true, the current permission represents no more access to the protected resource than does the specified permission.

The following code example displays the subset relationship between two permissions.

public static bool CheckSubSet(SmtpPermission permission)
{
    SmtpPermission allAccess = new 
        SmtpPermission(System.Security.Permissions.PermissionState.Unrestricted);
    return permission.IsSubsetOf(allAccess);
}
