示例
The example shows how to use the Revoke method with server permissions. The method is the same for database permissions.
'Connect to the local, default instance of SQL Server.
Dim svr As Server
svr = New Server()
'Define a ServerPermissionSet that contains permission to Create Endpoint and Alter Any Endpoint.
Dim sps As ServerPermissionSet
sps = New ServerPermissionSet(ServerPermission.CreateEndpoint)
sps.Add(ServerPermission.AlterAnyEndpoint)
'This sample assumes that the grantee already has permission to Create Endpoints.
'Enumerate and display the server permissions in the set for the grantee specified in the vGrantee string variable.
Dim spis As ServerPermissionInfo()
spis = svr.EnumServerPermissions(vGrantee, sps)
Dim spi As ServerPermissionInfo
Console.WriteLine("=================Before revoke===========================")
For Each spi In spis
Console.WriteLine(spi.Grantee & " has " & spi.PermissionType.ToString & " permission.")
Next
Console.WriteLine(" ")
'Remove a permission from the set.
sps.Remove(ServerPermission.CreateEndpoint)
'Revoke the create endpoint permission from the grantee.
svr.Revoke(sps, vGrantee)
'Enumerate and display the server permissions in the set for the grantee specified in the vGrantee string variable.
spis = svr.EnumServerPermissions(vGrantee, sps)
Console.WriteLine("=================After revoke============================")
For Each spi In spis
Console.WriteLine(spi.Grantee & " has " & spi.PermissionType.ToString & " permission.")
Next
Console.WriteLine(" ")
'Grant the Create Endpoint permission to the grantee.
svr.Grant(sps, vGrantee)
'Enumerate and display the server permissions in the set for the grantee specified in the vGrantee string variable.
spis = svr.EnumServerPermissions(vGrantee, sps)
Console.WriteLine("=================After grant=============================")
For Each spi In spis
Console.WriteLine(spi.Grantee & " has " & spi.PermissionType.ToString & " permission.")
Next
Console.WriteLine("")
