Parameters

target: IPermission

An IPermission to combine with the current permission.

A new SmtpPermission permission that represents the union of the current permission and the specified permission.

Examples

The following example creates a permission object that is the union of two permission objects.

static SmtpPermission^ UnionWithFull(
    SmtpPermission^ permission)
{
    SmtpPermission^ allAccess = 
        gcnew SmtpPermission(PermissionState::Unrestricted);
    return (SmtpPermission^) permission->Union(allAccess);
}

public static SmtpPermission UnionWithFull(SmtpPermission permission)
{
    SmtpPermission allAccess = new
        SmtpPermission(System.Security.Permissions.PermissionState.Unrestricted);
    return  (SmtpPermission)  permission.Union(allAccess);
}

The Union method returns a permission that represents all the states represented by both the current permission and the specified permission. Any demand that passes either permission passes their union.
