这是我的代码：
http://i43.tinypic.com/acpgdd.jpg
entities = new SamaEntities();
var institute_ContractInstitute = entities.ContractInstitutes;
我在观看页面中收到此错误
institute_ContractInstitute名称'institute_ContractInstitute' 在当前上下文中不存在
这是什么意思？
这是ContractInstitute Class：

答案 0 :(得分：0)
我在观看页面中收到此错误
当前上下文中不存在名称“institute_ContractInstitute”
这正是它所说的内容：当前上下文中没有名称为institute_ContractInstitute的变量，即您的程序当前所在的位置。
在var institute_ContractInstitute = ...之后放置断点，然后您可以在Watch窗口中检查其内容。
答案 1 :(得分：0)
可能这个问题是由于延迟加载造成的。 entity.ContractInstitutes中的任何数据都没有被加载。尝试使用List＆lt;＆gt;输入变量并使用.ToList（）将ContractInstitutes放入列表中。
