问题描述：

I''m developping a windows form application with ADO .Net entity data model , how can i fill a DataTable

DataTable dt = new DataTable()

来自数据库使用dataBaseEntities？

这里是我的查询：

from the data base using dataBaseEntities?
here is my query:

from data in db.Sources
where data.IdTheme==idtheme
select data.Url;

答

您是否有任何特定原因需要转换IEnumerable< string>进入DataTable？

无论如何你可以做这样的事情（未经测试）：

Is there any specific reason why you would want to transform your IEnumerable<string> into a DataTable?

Anyway you can probably do something like this (untested):

var queryResult = from data in db.Sources
where data.IdTheme==idtheme
select data.Url;


var dt = new DataTable();
dt.Columns.Add("Url");
foreach (var url in queryResult)
{
    var newRow = dt.NewRow();
    newRow["Url"] = url;
    dt.Rows.Add(newRow);
}
