function CheckAccess (
    userName : String,

    secDesc : byte[], 
    requiredOperations : ResourceOperation[]
) : boolean

Parameters

userName
The name of the user requesting access to the report server.

userToken
A user account token. This token is primarily used by the report server as a handle to a Microsoft Windows account in support of credential management for Windows authentication.

secDesc
The security descriptor for the item.

requiredOperations
The operations being requested by the report server for a given user.

Return Value

Returns true if the currently authenticated user is granted access to the item based on the supplied operation and security descriptor.

Example

The following example code uses the CheckAccess method to evaluate a user's authorization credentials against a security descriptor for an item in the report server database. The example makes use of the overloaded CheckAccess method that takes a single operation as an argument.

' Overload for array of resource operations
Public Function CheckAccess(userName As String, userToken As IntPtr, secDesc() As Byte, requiredOperations() As ResourceOperation) As Boolean
   Dim operation As ResourceOperation
   For Each operation In  requiredOperations
      If Not CheckAccess(userName, userToken, secDesc, operation) Then
         Return False
      End If
   Next operation
   Return True
End Function 'CheckAccess
// Overload for array of resource operations
public bool CheckAccess(string userName, IntPtr userToken, byte[] secDesc, ResourceOperation[] requiredOperations)
{
   foreach(ResourceOperation operation in requiredOperations)
   {
      if (!CheckAccess(userName, userToken, secDesc, operation))
         return false;
   }
   return true; 
}
