Tsql 使用参数获取存储过程结果时出现EF6语法错误

我不明白为什么在执行这行代码时会出现语法错误：

return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Kitti_getProductGroupDetail_Result>("Kitti_getProductGroupDetail @ProductGroupId", @params);

ProductGroupId肯定正在被填充。EF不喜欢我的代码的什么地方？我有一个类似的方法，它不需要参数来执行存储过程——它工作得很好

 // this works just fine
    public virtual ObjectResult<Kitti_getProductDetailsAndCategory_Result> Kitti_getProductDetailsAndCategory()
    {
        return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Kitti_getProductDetailsAndCategory_Result>("Kitti_getProductDetailsAndCategory");

        //ExecuteFunction changed to ExecuteStoreQuery
    }

//这很好用
公共虚拟对象结果Kitti_GetProductDetails和Category（）
{
返回（（IObjectContextAdapter）this.ObjectContext.ExecuteStoreQuery（“Kitti_GetProductDetails和Category”）；
//ExecuteFunction更改为ExecuteStoreQuery
}
