OData

安装OData环境：

Install-Package Microsoft.AspNet.Odata

安装EF环境：

Install-Package EntityFramework

Code First连接字符串：web.config中

 <connectionStrings>
    <add name="ProductsContext" connectionString="Data Source=.;Initial Catalog=OData2;Persist Security Info=True;User ID=sa;Password=123" providerName="System.Data.SqlClient" />
  </connectionStrings>

配置路由：WebApiConfig

config.Count().OrderBy().Select().Filter().Expand().MaxTop(null);
            ODataModelBuilder builder = new ODataConventionModelBuilder();
            builder.EntitySet<student>("student");
            builder.EntitySet<score>("score");
            builder.EntitySet<course>("course");
            builder.EntitySet<teacher>("teacher");
            config.MapODataServiceRoute(
                routeName: "odata",
                routePrefix: "odata",
                model: builder.GetEdmModel());
