想问下: public static DataSet ConvertToDataSet <T> (IList <T> list)中的
ConvertToDataSet <T> 代表什么呀。!
我想引用这段代码我是这样写的:
Category category = new Category();
NHibernateHelper.ConvertToDataSet <T> (category.GetCategories);
总提示: CS0246: 找不到类型或命名空间名称“T”(是否缺少 using 指令或程序集引用?)


[解决办法]
T是具体类型的名字
如果class Category
NHibernateHelper.ConvertToDataSet <Category> (category.GetCategories);
