The following members return DirectoryAccessRule objects:

• DirectoryAccessRule.Allow(String[])
• DirectoryAccessRule.Deny(String[])

Remarks

Define a directory access rule to allow or deny resource load from all/specific file directories in your application. You can use the static Allow(String[]) or Deny(String[]) method to create directory access rules. Use the SetRules(IAccessRule[]) method to register these rules.

Examples:

C#

// Image load from file directories is allowed
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Allow());

VB.NET

' Image load from file directories is allowed
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Allow())

C#

// Image load from file directories is denied
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Deny());

VB.NET

' Image load from file directories is denied
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Deny())

C#

// Image load is allowed only from the specified file directory
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Allow("C:\StaticResources\"));

VB.NET

' Image load is allowed only from the specified file directory
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Allow("C:\StaticResources\"))

C#

// Image load from the specified file directories is denied
// images from other file directories are accessible
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Deny("C:\StaticResources\")); 

VB.NET

' Image load from the specified file directory is denied
' Images from other directories are accessible
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(DirectoryAccessRule.Deny("C:\StaticResources\"))
