命名空间：  System.Data.Services
程序集：  Microsoft.Data.Services（在 Microsoft.Data.Services.dll 中）

语法

声明
Public Sub SetEntitySetAccessRule ( _
    name As String, _
    rights As EntitySetRights _
)
用法
Dim instance As DataServiceConfiguration
Dim name As String
Dim rights As EntitySetRights

instance.SetEntitySetAccessRule(name, _
    rights)

public void SetEntitySetAccessRule(
    string name,
    EntitySetRights rights
)

public:
virtual void SetEntitySetAccessRule(
    String^ name, 
    EntitySetRights rights
) sealed

abstract SetEntitySetAccessRule : 
        name:string * 
        rights:EntitySetRights -> unit 
override SetEntitySetAccessRule : 
        name:string * 
        rights:EntitySetRights -> unit 

public final function SetEntitySetAccessRule(
    name : String, 
    rights : EntitySetRights
)

参数

• name
  类型：System.String
  要设置权限的实体集的名称。

• rights
  类型：System.Data.Services.EntitySetRights
  将要授予此资源的访问权限作为 EntitySetRights 值进行传递。

实现

IDataServiceConfiguration.SetEntitySetAccessRule(String, EntitySetRights)

注释

当您为 name 参数指定星号值 (*) 时，将为未显式设置权限的所有实体集设置权限。

示例

此示例显示了基于 Northwind 的数据服务的代码隐藏页面，并将访问权限授予所选实体集。

Imports System.Data.Services
Imports System.Linq
Imports System.ServiceModel.Web

Public Class Northwind
    Inherits DataService(Of NorthwindEntities)

    ' This method is called only once to initialize service-wide policies.
    Public Shared Sub InitializeService(ByVal config As DataServiceConfiguration)
        ' Grant only the rights needed to support the client application.
        config.SetEntitySetAccessRule("Orders", EntitySetRights.AllRead _
             Or EntitySetRights.WriteMerge _
             Or EntitySetRights.WriteReplace)
        config.SetEntitySetAccessRule("Order_Details", EntitySetRights.AllRead _
            Or EntitySetRights.AllWrite)
        config.SetEntitySetAccessRule("Customers", EntitySetRights.AllRead)
    End Sub
End Class

using System.Data.Services;
using System.Linq;
using System.ServiceModel.Web;

namespace NorthwindService
{
    [ServiceBehavior(IncludeExceptionDetailInFaults = true)]
    public class Northwind : DataService<NorthwindEntities>
    {
        // This method is called only once to initialize service-wide policies.
        public static void InitializeService(DataServiceConfiguration config)
        {
            // Grant only the rights needed to support the client application.
            config.SetEntitySetAccessRule("Orders", EntitySetRights.AllRead
                 | EntitySetRights.WriteMerge
                 | EntitySetRights.WriteReplace);
            config.SetEntitySetAccessRule("Order_Details", EntitySetRights.AllRead
                | EntitySetRights.AllWrite);
            config.SetEntitySetAccessRule("Customers", EntitySetRights.AllRead);
            config.DataServiceBehavior.MaxProtocolVersion =
                System.Data.Services.Common.DataServiceProtocolVersion.V3;
        }
    }
}
