One columned datatable to List<string>
提问by Sin5k4
I have a datatable
which contains only one column and all items are strings. How can I convert this to a List<string>
using LINQ for example?
我有一个datatable
只包含一列,所有项目都是字符串。例如,如何将其转换为List<string>
使用 LINQ?
I Tried:
我试过:
DataRow[] rows = dtusers.Select();
var qq = from RowCollection in rows
select new { UserCode = LibStatic.ToStr(RowCollection["UserCode"]) };
List<string> users = new List<string>();
users = qq.Cast<string>().ToList();
There is the easyway which always works:
有一种总是有效的简单方法:
foreach (DataRow dr in dtusers.Rows)
{
users.Add(dr[0].ToString());
}

You can use LINQ queryto do that.
您可以使用LINQ 查询来做到这一点。
List<string> list = dtusers.AsEnumerable()
.Select(r=> r.Field<string>("UserCode"))
.ToList();
