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。

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);
    }
}

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

注解

如果为name参数指定星号值 (*) ，则会为未显式设置权限的所有实体集设置权限。
