参数

userName

String

userToken

IntPtr

nativeint

示例

以下示例代码使用 [CheckAccess 方法 (String、 IntPtr、 Byte<xref：Microsoft.ReportingServices.Interfaces.IAuthorizationExtension.CheckAccess%2A> 方法根据报表服务器数据库中项的安全描述符评估用户的授权凭据。 此示例使用重载的 [CheckAccess 方法 (String、 IntPtr、 Byte<xref：Microsoft.ReportingServices.Interfaces.IAuthorizationExtension.CheckAccess%2A> 方法，该方法采用单个操作作为参数。

' 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;  
   }
