function CheckAccess(

) : boolean
参数
- userName
类型：System.String
The name of the user requesting access to the report server.
- userToken
类型：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
类型：array<System.Byte[]
The security descriptor for the item.
- requiredOperations
类型：array<Microsoft.ReportingServices.Interfaces.ResourceOperation[]
The operations being requested by the report server for a given user.
返回值
类型：System.Boolean
Returns true if the currently authenticated user is granted access to the item based on the supplied operation and security descriptor.
示例
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;
}
