) : boolean
Parâmetros
- userName
Tipo: System.String
The name of the user requesting access to the report server.
- userToken
Tipo: System.IntPtr
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
Tipo: array<System.Byte[]
The security descriptor for the item.
- requiredOperation
Tipo: Microsoft.ReportingServices.Interfaces.ReportOperation
The operation being requested by the report server for a given user.
Valor de retorno
Tipo: System.Boolean
Returns true if the currently authenticated user is granted access to the item based on the supplied operation and security descriptor.
Exemplos
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.
Public Function CheckAccess(userName As String, userToken As IntPtr, secDesc() As Byte, requiredOperation As ReportOperation) As Boolean
Dim acl As AceCollection = DeserializeAcl(secDesc)
Dim ace As AceStruct
For Each ace In acl
' First check to see if the user or group has an access control entry for the item
If userName = ace.PrincipalName Then
' If an entry is found, return true if the given required operation
' is contained in the ACE structure.
Dim aclOperation As ReportOperation
For Each aclOperation In ace.ReportOperations
If aclOperation = requiredOperation Then
Return True
End If
Next aclOperation
End If
Next ace
Return False
End Function 'CheckAccess
Private Function DeserializeAcl(secDesc() As Byte) As AceCollection
Dim bf As New BinaryFormatter()
Dim sdStream As New MemoryStream(secDesc)
Dim acl As AceCollection = CType(bf.Deserialize(sdStream), AceCollection)
Return acl
End Function 'DeserializeAcl
public bool CheckAccess(string userName, IntPtr userToken, byte[] secDesc, ReportOperation requiredOperation)
{
AceCollection acl = DeserializeAcl(secDesc);
foreach(AceStruct ace in acl)
{
// First check to see if the user or group has an access control entry for the item
if (userName == ace.PrincipalName)
{
// If an entry is found, return true if the given required operation
// is contained in the ACE structure.
foreach(ReportOperation aclOperation in ace.ReportOperations)
{
if (aclOperation == requiredOperation)
return true;
}
}
}
return false;
}
private AceCollection DeserializeAcl(byte[] secDesc)
{
BinaryFormatter bf = new BinaryFormatter();
MemoryStream sdStream = new MemoryStream(secDesc);
AceCollection acl = (AceCollection)bf.Deserialize(sdStream);
return acl;
}
