如何两个数据源组合成一个？ [英] how to combine two data source into one?

问题描述

我有两个表，和1对象记录， 我想要从两个表中的数据为1的GridView，（两个表具有相同的字段），我不能加入，因为我需要显示所有的行

这是我的code：

  VAR的查询=从所有DB.Movies
            其中，all.IsActive
            选择新MoviesObject
            {
                PHOTOID = all.PhotoId，
                标题= all.Title，
                说明= all.ShortDescription
            };
VAR querytwo =所有在DB.movi​​eslisttwo
               其中，all.IsActive
               选择新MoviesObject
               {
                   PHOTOID = all.PhotoId，
                   标题= all.Title，
                   说明= all.ShortDescription
               ;
返回query.ToList（）;
 

解决方案

 返回query.Concat（query2）.ToList（）;
 

另外，您也可以致电 .Union（）跳过重复。

i have records in two tables, and 1 object, i want to retrieve data from both tables into 1 gridview, (both tables have same fields) i can not have joins because i need to show all rows

here is my code:

var query = from all in DB.Movies
            where all.IsActive
            select new MoviesObject
            {
                PhotoId = all.PhotoId,
                Title = all.Title,
                Description = all.ShortDescription
            };
var querytwo = from all in DB.movieslisttwo
               where all.IsActive
               select new MoviesObject
               {
                   PhotoId = all.PhotoId,
                   Title = all.Title,
                   Description = all.ShortDescription
               ;
return query.ToList();

解决方案

return query.Concat(query2).ToList();

Alternatively, you can call .Union() to skip duplicates.
