C# 从Odata服务读取Json输出

我试图以json格式读取odata服务的输出。但我得到的错误消息如下所示

响应有效负载不是有效的响应有效负载。请确保顶级元素是有效的Atom或JSON元素，或者属于命名空间

您输入的JSON字符串无效，因为它的属性名中带有“.”。 无法解析odata.metadata

如果您将其更改为odata_元数据，或者可能使用此处提供的解决方案：

感谢您的回复。我已将odata格式设置为Nometadata，但仍会收到相同的错误。当前的输出是{value:[{ProductID:33，ProductName:Geitost，SupplierID:15，CategoryID:4，QuantityPerUnit:500g，单价：2.5000，UnitsInStock:112，UnitsOnOrder:0，ReorderLevel:20，Discontracted:false}]@travisco\u nabisco

NorthwindEntities dc = new NorthwindEntities(new Uri("http://services.odata.org/V3/Northwind/Northwind.svc/"),DataServiceProtocolVersion.V3);
        dc.Format.UseJson(new EdmModel());
        DataServiceQuery<Product> query = (DataServiceQuery<Product>)from o in dc.Products
            where o.UnitPrice > 0
            select o; query.execute();


{"odata.metadata":"http://services.odata.org/V3/Northwind/Northwind.svc/$metadata#Products","value":[{"ProductID":24,"ProductName":"Guaran\u00e1 Fant\u00e1stica","SupplierID":10,"CategoryID":1,"QuantityPerUnit":"12 - 355 ml cans","UnitPrice":"4.5000","UnitsInStock":20,"UnitsOnOrder":0,"ReorderLevel":0,"Discontinued":true},{"ProductID":33,"ProductName":"Geitost","SupplierID":15,"CategoryID":4,"QuantityPerUnit":"500 g","UnitPrice":"2.5000","UnitsInStock":112,"UnitsOnOrder":0,"ReorderLevel":20,"Discontinued":false}]}
